the original radio (Delco) is stuck in station scan mode ?
yes, scan is off, there is a little SC in display that goes on and off
when you cycle the scan button but radio still scans

Will it pick up local stations as it scans, or is it totally "deaf"?
Have you checked the antenna connection? If you're in a metro area, try
running a 4 foot or so piece of solid wire right into the center
conductor of the antenna jack. If the tuner is working, this should be
enough for it to pick up a station.


Thanks for reply, radio is still not functioning.

Yes the radio will tune to a station and play it clearly (no static or
distortion) pausing for about 3-5 seconds and then start scanning again
just like it should when in scan mode.

So that is why i say it is stuck in scan mode, it may not be in scan mode
but radio behaves that way. Maybe it is really seek mode problem ?

when one toggles the scan button a little SC indicator toggles on and off so
i assume the button is not stuck and is sending the appropriate signal.

when i press seek mode the radio immediately starts seeking so i can
interrupt the pause of 3-5 seconds by using the seek button so i presume
seek function is working ?


Did you check all the fuses? This may not be the problem but it's
simple to check. I was surprised at the way the fuses affected the
stock Delco radio in an '89 Corsica. On most older aftermarket radios,
the "ignition" wire was the main power for the radio, and the "battery"
wire just maintained the station memory. If you didn't hook up the
"battery" wire, the radio would work, but would forget all the station
presets when you turned off the ignition key. The Delco in the Chevy
had "ignition" and "battery" power as well, but the "battery" power
seemed to actually run a lot of the digital part of the radio. I
managed to blow the fuse that supplied battery power to the radio, and
when I turned on the key, the tuner was unresponsive and I only got
static. I could make the static louder and softer with the volume
knob, but couldn't tune anything.


have not but will check


Is there a way to disable the scan feature by modifying the pcb board, a
jumper, patch, etc

Maybe the button is sticking, or another button is stuck down. Has the
radio gotten any coffee spilled inside of it? You might be able to
disassemble the radio and clean the button contacts. You might also
take a look at the interconnections between the various circuit boards
(solder joints, plug-in connectors) and resolder or reseat the
connectors.


that would be next option but i was hoping some one had this problem and
maybe it is a familiar problem with a known solution


any suggestions for radio replacement that kinda blends in (basic black
face, green display)

Another Delco from a junkyard. The last time I shopped for an entry-level
car stereo about two years ago, it was hard to find one that didn't have
several square inches of disco lights on the face.


same here i have pioneers in other cars with lots of blue flashing lcd stuff
and i really just want something mild, Alpine probably work ? Blaupunkt
used to have lots of basic black faces


Thanks agian
