I have not been able to open it yet...PC issuesDid you look in the service manual I sent you? The AIM might show the ghosted view of the assembly in the section that has the dash control hook up or in the AC section..??
Not doubt those GM are better, but for what I fo, I've had decent luck with the Haynes, and my antique Motors Manual....👍If you are going to work on your car you should buy the set of GM manuals for it. They lots of details and actual pictures that all apply to your car.
Haynes books not so much.
