Car: 1992 GMC Sonoma 2.8L Manual
Miles: ONLY 197,000 miles
Name: Goes by the name of lucky (see http://community.cartalk.com/discussion/2300343/1992-gmc-sonoma-2-8l-sometimes-wont-start-not-even-turn-over-when-engine-is-warm#latest and http://community.cartalk.com/discussion/2300344/1992-gmc-sonoma-2-8l-windshield-wipers-stop-in-middle-and-or-keep-going-a-few-cycles#latest)
Symptom: When ever I put the switch to OFF or VENT or HEAT the console starts to smoke (if the truck is on, of course). I noticed that I can hear the A/C running even when I put switch to one of the off positions.
Fixes: I have not had a mechanic take a look at this yet. They usually complain about other things when I bring it in. Little things like “your brakes are almost gone” (big deal, I don’t need breaks because it is a stick shift) or “your tires are showing their metal wire” (big deal, I’ve had a front tire blow out before at 70 mph… on this same truck come to think of it).
Current work arounds: I keep the A/C on all the time even if I don’t need it. I tried pulling the fuse and that did work, I can put the switch anywhere without the fear of smoke but it turns off the blower motor as well. If the blower is off then I’ll have a hard time getting heat in the winter (Florida winters are very cold, down to the low 40s sometimes)
Feeble attempt to diagnose: I think I’ve seen card board be used as insulation inside the console before, I think whatever insulation was in there started degrade. I’m thinking that I’d like to track down the wires for and put the A/C on a different switch so I can still turn off the A/C and keep the blower going for the cold cold winter. Are there simpler solutions?
