Unhappy

Does anyone have any wiring info to the central panel which controls the AC. There are two pcb's that have various connectors, but someone has spliced every different color wire there is to them.

The problem is I can't find how the power gets back to the compressor/clutch.

Any help would greatly be appreciated!

do you have power to the clutch cycling switch on the accumulator that is under the hood.

I have a 1985 Firebird with a 1995 3.4 under there. Took out the 700R4 tranny, this 3.4 engine is so strong.

chev64,

Yes, I checked the switch and it does have power. I noticed that under the dash, actually behind the a/c,wiper,heater pod there is a relay. It has 5 contacts and goes to one of the pcb's in the pod. It doesn't have any power coming or going from it. Without a wiring diagram its hard to say where it is suppose to get power. The fan blower works and so does the wipers although sometimes they can't be shutoff, and the lights come on to the pod. The a/c switch light comes on but no power to the clutch.

Ked67,

I have checked this web site and you are right, it does have alot of info. What I gathered from all the various replies is these pods that make up the digital circuitry are not as reliable. The biggest problem is there seems to be no real wiring diagrams to the dash as a whole.

<HR></BLOCKQUOTE>Chev64, I lied, sorry about that the clutch cycling switch has no power. I went back and checked it. Does the power come from the ecm to the ac relay back to the switch, and then to the clutch? The wiring has been splice so much I don't know what color goes where?

Thanks,
rsisk

According to our Mitchell program, there is a relay on the drivers side cowl near the brake booster that is the relay for the compressor clutch. The one under the dash is for the blower.

Chev64 that is more info than I've seen in awhile. I never would have guessed that it was in the a/c circuit. The ecm on the passenger side, the right pod right side of steering wheel, and now the a/c relay drivers side. Chevrolet must have run out of room under the dash. Feels like I am working on a vette here with all this room. Ha! Do you know where the power originates from to the relay and where it goes? I would guess thru the right pod back to the ecm, and the other side back to the recycling switch to the compressor, but I am not sure.

Thanks again for the info....

I need to know wether your Camaro is a 6 cyl or an 8 cyl cause there is a difference in the schematic.

Thanks to all that helped in this problem. I did finally get the a/c working by replacining the right pod. The only thing left is turning off the wipers. Can't seem to stop them.

For all you newcomers to this board, there is alot of knowledge and help here!

Anyway thanks to all..
