Makes me suspect a loose obstruction hanging up or perhaps the controls are intermittent themselves? That was a biggie with one of the series of Chebby pickumups in '97 or thereabouts...the dampers are electric motors and combined with their tendency to lock up and then burnout the motor the actual control circuitry was subject to a service bulletin that wasn't a recall but if the customer complained they'd swap it out... -- |

Our '99 Toyota 4Runner has a heater problem that's driving me (more) nuts . The heater apparently isn't getting enough coolant flow , and isn't putting out enough heat . I've checked all the hoses from the motor thru the valve and heater core and back to the engine , hoses are OK and the core isn't plugged . I've also flushed the entire system , all hoses and the core and associated plumbing . After flushing it out it'll do OK for a short time then it's back to not enough heat . Pertinent info - the water control valve is cable operated from the dash along with the gating for airflow in the heater box . I don't think there's a t-stat type device in there for temp control , but if there is one and it's malfing that might explain it . The coolant level is up , and circulating when observed in the radiator . This has really got me stumped , and the wife is getting pretty hot herself about it - we're getting into the cold season here and she's the main driver . -- Snag Are you sure that the blend doors are opening and closing properly? I've had them fail on various model cars. Until recently I had a 2002 Mitsubishi that sometimes would not produce heat after the temp knob was moved from full cold to heat. Turned out that the blend door actuator would get intermittently get stuck in the fully closed position. I followed the cable down to where it entered the duct work and installed a small block of wood to prevent the cable from being moved to the fully cold position. The difference was maybe a 16th of an inch at the knob end. Car had heat for 3 winters until other issues signaled it's demise. Not the problem , I can observe the mechanism moving when I move the control knob . Unless there is a t-stat in there that controls them and the cable only signals it for heat . -- Snag What mechanism can you observe move? On the Mit, I could see the cable move a nylon connector over it's full range of motion as observed from outside the blend door housing. However, the blend door shut motor itself is inside the housing and that was what was intermittently failing in the fully closed position - by design. If you fast forward to 7:00 in the following video, you'll see what I mean. https://www.youtube.com/watch?v=HywkYSNRGug What I did was keep playing with the control knob until the shut motor activated and opened the doors. I then physically prevented the cable from ever moving to the fully closed position, thereby "eliminating" the shut motor from the system. My Dad has a mid-2000's Mercury Sable. He had poor heat also. He had a blend door issue, but it cost him $800 to fix. It was mostly labor because half the dash board had to be taken apart to get to the problem. Blend door issues are a common cause of no/low heat. Not sure about your year, but many earlier 4-runners had a problem with the water control valve. The control shaft pulled out of the "spool valve" that controls the water flow - moving the shaft opens a roughly 1/4 inch hole instead of the 5/8" hole it is supposed to open. I replaced a few dozen of those (and on some other Toyotas as well) Remove the valve and check it carefully. Valve has been removed and checked , I get full range of motion and it stays put on the shaft . On the blend door thing , I'm observing the levers and stuff on the top of the heater outlet , all seems to be working properly . I can actually hear the doors inside moving when I move the control lever . Whatever is happening is intermittent. I HAVE seen the heater valves appear to be good when looked at, when the heat is working. The trick is to remove the valve when the heat is NOT working and confirm. |

There are purge valves on vehicles where the heater core is above the level of the top of the rad or the top of the engine. Like the defroster core on an old R12 . |

its best to run water both directions thru the heater core, and pulse compressed air thru the heater core at the same time, replacing all the coolant with plain water, then drain, and replace all the coolant with a 50 /50 mixture of NEW coolant

Even changing the thermostat temperature can cause problems (put in 180 instead of 190 and it takes too long to reach the 190 minimum operating temperature - light comes on. The Honda Odyssey uses Variable Cylinder Management which shuts down 3 of the 6 cylinders when the ECU determines that they are not needed. Many Ody owners hate it for a variety of reasons. One guy determined that VCM will never engage below a engine coolant temp (ECT) of 167F. He determined that a ~100 ohm resistor placed between the ECT2 sensor and the ECU fools the ECU into thinking that the ECT is about 15 degrees cooler and essentially disables VCM. The 15 degrees Is not enough to impact the fuel air mixture at cooler ECTs so there does not appear to be any negative impact on vehicle operation or performance. Dozens of us have been using the resistor for about a year now and there have been no reports of issues. Vehicles have passed state inspections with the resistor installed. The device is plug and play, using Honda connectors, so it can be removed in about 20 seconds if someone wants to ensure that the resistor is not causing whatever problem the van is having. The VCM system causes more problems than it is worth. Running with 6 cylinders all the time makes the van so much more enjoyable to drive. (Honda had to use special (read: expensive) motors mounts and a Noise Cancellation system to compensate for the physical vibration and auditory issues that are present when the back 3 cylinders are shut down. The motor mounts are known to go bad because of the VCM so we are happy to know that we've eliminated the vibration issue that causes them to go bad. |

Life was simpler back then. ^_^ [8~{} Uncle Cool Monster In today's cars you are almost guaranteen you will, at the very least, throw a code and turn on the CEL. The computer knows from the outside air temperature, how long it should take to come to a specific operating temperature and if it takes too long, or not long enough, it reports an error. Even changing the thermostat temperature can cause problems (put in 180 instead of 190 and it takes too long to reach the 190 minimum operating temperature - light comes on. The Honda Odyssey uses Variable Cylinder Management which shuts down 3 of the 6 cylinders when the ECU determines that they are not needed. Many Ody owners hate it for a variety of reasons. One guy determined that VCM will never engage below a engine coolant temp (ECT) of 167F. He determined that a ~100 ohm resistor placed between the ECT2 sensor and the ECU fools the ECU into thinking that the ECT is about 15 degrees cooler and essentially disables VCM. The 15 degrees Is not enough to impact the fuel air mixture at cooler ECTs so there does not appear to be any negative impact on vehicle operation or performance. Dozens of us have been using the resistor for about a year now and there have been no reports of issues. Vehicles have passed state inspections with the resistor installed. The device is plug and play, using Honda connectors, so it can be removed in about 20 seconds if someone wants to ensure that the resistor is not causing whatever problem the van is having. The VCM system causes more problems than it is worth. Running with 6 cylinders all the time makes the van so much more enjoyable to drive. (Honda had to use special (read: expensive) motors mounts and a Noise Cancellation system to compensate for the physical vibration and auditory issues that are present when the back 3 cylinders are shut down. The motor mounts are known to go bad because of the VCM so we are happy to know that we've eliminated the vibration issue that causes them to go bad. no doubt this tampering breaks a bunch of fedreal laws. cadillac years ago had a 8 6 4 engine that didnt work |

On a lot of vehicles (don't know about the Odyssy) the torque converter also will not lock below the target temperature - and running without lock-up not only burns more fuel, but also burns out transmissions due to overheating caused by the slippage in the converter (which is not allowed for in the cooling design) Some also will never shift into the top (overdrive) gear untill proper operating temperature is acheived. |

If a customer is happy with their device/vehicle and feel that they are taking advantage of the features that matter to them, they are more likely to remain loyal. I know lots of people that are technologically challenged and could never figure out how to program/use many of the features in a high tech vehicle on their own. A class is a great idea. |

Just sayin' The solution to the problem would be interesting Removing the thermostat on some engines will cause serious overheating, while on other engines it could cause the engine to never get up to operating temperature. If running without a thermostat it is a real good idea to install a restrictor plate or baffle with a roughly 3/4" hole in place of the thermostat. What may work in a Florida swamp or what works in the Arctic Circle are not the same. I ran engines for years without a T-stat. You live in a rather warm area of the country as I recall. Around here, in the summer when it was hot, me and the guys would remove the thermostats from the engines in our vehicles in the days before cars and trucks were produced with all kinds of electronic engine controls. My old cars from the 1960's and 70's ran great in the summer without thermostats but I had to reinstall the thermostats when the weather got cool. Life was simpler back then. ^_^ [8~{} Uncle Cool Monster In today's cars you are almost guaranteen you will, at the very least, throw a code and turn on the CEL. The computer knows from the outside air temperature, how long it should take to come to a specific operating temperature and if it takes too long, or not long enough, it reports an error. Even changing the thermostat temperature can cause problems (put in 180 instead of 190 and it takes too long to reach the 190 minimum operating temperature - light comes on. The Honda Odyssey uses Variable Cylinder Management which shuts down 3 of the 6 cylinders when the ECU determines that they are not needed. Many Ody owners hate it for a variety of reasons. One guy determined that VCM will never engage below a engine coolant temp (ECT) of 167F. He determined that a ~100 ohm resistor placed between the ECT2 sensor and the ECU fools the ECU into thinking that the ECT is about 15 degrees cooler and essentially disables VCM. The 15 degrees Is not enough to impact the fuel air mixture at cooler ECTs so there does not appear to be any negative impact on vehicle operation or performance. Dozens of us have been using the resistor for about a year now and there have been no reports of issues. Vehicles have passed state inspections with the resistor installed. The device is plug and play, using Honda connectors, so it can be removed in about 20 seconds if someone wants to ensure that the resistor is not causing whatever problem the van is having. The VCM system causes more problems than it is worth. Running with 6 cylinders all the time makes the van so much more enjoyable to drive. (Honda had to use special (read: expensive) motors mounts and a Noise Cancellation system to compensate for the physical vibration and auditory issues that are present when the back 3 cylinders are shut down. The motor mounts are known to go bad because of the VCM so we are happy to know that we've eliminated the vibration issue that causes them to go bad. On a lot of vehicles (don't know about the Odyssy) the torque converter also will not lock below the target temperature - and running without lock-up not only burns more fuel, but also burns out transmissions due to overheating caused by the slippage in the converter (which is not allowed for in the cooling design) Some also will never shift into the top (overdrive) gear untill proper operating temperature is acheived. As far as we have been able to tell, the Ody (or Pilot) does not exhibit any TC lockup issues with the device installed. Hundreds of devices used for thousands of miles; highway, city, towing, etc. No high rev issues, no shuddering, no heat buildup. We're happy. |

The steering wheel heater does so that is warm when I get in. There may be a reason why the seat heaters do not come up with the remote start. The manual for my Odyssey states: "Use the HI setting only to heat the seats quickly because it draws large amounts of current from the battery. If the engine is left idling for an extended period, do not use the seat heaters, even on the LO setting. It can weaken the battery, causing hard starting." Granted, the manual does not define what they mean by "an extended period" but perhaps even the 20 minutes that many remote starts shut down after is "extended" enough to weaken the battery. That said, my seat heaters are controlled by a rocker switch which means that I can set them to HI or LO and have them come on with the remote start. The problem is that I don't always remember to do that after I park. ;-) Still, a warm cabin, even if the leather is cold, is better than nothing. |
