How to remove heater / AC controls?

How can I remove the heater / AC controls? These are interchangeable between all thirdgens right?

Whenever I've been to the junkyard, I can remove everything except for this part of it.. (View image)..

But I don't know how to remove it or how I would put it back on. I would rather not cut and splice those wires.

Re: How to remove heater / AC controls?

Not all heater/ac controls are interchangeable. I believe the later models had high speed relay for the blower fan.

I used the Firebirds Parts CD not the Camaro one but I'm showing heater control for 83-89, 90-92. I'm too lazy to dig out the Camaro one also.

Looks like the #4 part you are questioning is the Air Valc Actr Vac Harness part 14101552 (from 91-92 F Body with C60 [Air Conditioning]). Looks like it has various vac connections and possibly ties back into the other harness for the controls.

Two small push nuts hold the harness in place on the long studs. On the outside of the studs underneath are two small screw/bolts. BTW, at some point the following link will be useful:
