*Just put your ammeter into the heater blower fuse connector and you
get the current of the blower motor.


That's an interesting idea.

The fuse for the blower motor is called the "infamous F76" for a reason.

It's a 40 amp fuse under the glovebox but it's in a really inaccessible
spot; however, it's right side up, so, the wires going INTO it are
visible from the tips of your feet under the glove box.


So that's a possibility; but you'd have to cut the wires.

* Why would you have to cut the wires????
Simply remove the fuse and connect the ammeter. *You guys make your

It's kind of amazing the fuse is 40 amps, no? I mean a 1 hp
motor draws ~1500W And this heater blower is 480W?
Seems like a lot to me.....
