Does anyone know where the vacuum originates for the control valve for the heater water shutoff valve? I found the line and it went to the drivers side of the engine but couldn’t locate where it was connecte.
I just replaced my compressor on my 99 Tahoe with a donor, but on the rear of the unit there is a sensor that is a different color than the one that was on the original unit. The donor had rear heat a/c, I don’t have. Will this affect the operation of the compressor?
This is a little late in the game but where did you get the tool? I have the same problem with my 99 Tahoe, I’m going to try the HECASA removal tool.
