92 Lesabre no heat

is this blowing fuses at all because my dad had same problem if fuses are blowing like to never found out but under passenger side and we unplugged every sensor or relay and the last one we pulled it never blew a fuse since and it had something to do with the dinger and still works fine. but if not blowing fuse thats probably not whats wrong.

OK FUSE 2 60A is good. The square box looking fuses were all jumbled and put in randomly so they don't line up with the diagram. I did however check the one with the purple and black wire and it was showed voltage from the terminal. I swaped the fuse with another like kind with no change.

Can you tell me where the power for FUSE 3 comes from? I can see the red wires running from behind the fuse panel but was wondering where they start from. From both sides they run into a bundle that appears to disappear behind the firewall.

I haven't found any blown fuses as of yet but I'm not 100% certain which fuses to check. I've checked FUSE 17 inside the car and the FUSE 3 under the hood. I swapped them with other working fuses and did visual and continuity checks on them and they appear good.

I checked the Orange wire from the harness that would go into the control unit and it read 11.6volts. The blue wire read 8.4v. There was another orange wire coming out of the control unit but it read zero when the connectors were plugged in. Not sure if both wires are related other than color. I'm going to follow the hot orange wire to the circuit board and see what that reads. I have to take it apart first.

ok..I bypassed power across the orange wires in the harness and the blower motor came on. Does this mean the problem is with the Climate Contol Module? I was a little surprised with the wire being hot at all times. I didn't have to have the car in RUN to bridge the two wires.

Anyone have any suggestions on how to find a used C67 manual control module? I've checked with all the local junkyards and even many I've found online. I guess I'm looking for a junkyard that specializes in GM.

I found several yards offering control parts for C67.

This may be the actual control on the dash itself.

Or are you looking for the programmer box for C67?
Either way these might be ones to call as long as you can be clear which part you're wanting. I've ordered a part from one of the yards and they charged about $20 shipping for a heavier part for 150 miles away.

It might be worth checking some of these close to Dayton.

Thanks for the tip. I have the part number 16145214. But the online searches only describe it as Lesabre Limited C67. I'll give the ones close by a call. I called a yard east of Columbus who said he should have one but I really to don't want to drive an hour and a half for a possibility. Someone at work who lives near Granville, OH said there was a junkyard there that only takes GM vehicles.

Thanks, imidazol97 for the lead on the control module. Took a road trip yesterday afternoon and picked it up for $35, put it in this morning, and we're back in business. In fact, there's no hesitation between switching from heat to a/c and the rr defogger comes on with the first push. I think the control module had been on the fritz ever since I bought the car 7 yrs ago.

Which junkyard were you able to get it from?

I was getting ready to suggest some that aren't showing parts in the website lists. There's one in Richmond on the far northwest side that is a possibility.

I'm glad for you that it was the control panel. And it works.

Thanks for coming back to let everyone know what you found. That may help another poster.

I went with National Auto and Truck in Wapakoneta. Mainly because they had listed an actual price in the search instead of $$/call for pricing and they were within 10 miles of the Richmond store.

Thanks, again.
