I have a 77 3/4 4x4 with A/C the PO appears to have replaced the evaporator core, I am going through the system to clean and get working properly. My truck has the thermostatic switch that attaches to the inlet line on the evap. I read the GM service manual and it says to mark EXACT location before removal I am sure the OP didn't do that. What I need is that EXACT location to reattach the capillary tube. If anybody has specific info it would be greatly appreciated.
