I have a 1996 K2500 Suburban 6.5 Vin F. I currently have the motor and drivetrain out for maintenance, and cant for the life of me figure out where the vaccum lines for the ACTUATOR. Heater. VALVE go. I have searched my service manual, google, and google images. It is a small solenoid mounted to the right of the ac accumulator. It has to hose barbs and a 2 pin electrical connector. I am not sure if it was connected when removed, but my A/c is currently not working(looks like compressor clutch is slipping). Would this have to do with it? The previous owner screwed up some of the vaccum lines/ ellectrical wiring. Very frustrating . I have searched for full info on it for hours to no avail. Best i have found is lower hose connects to heater hose.

I believe it is GM PN 15165891

This website diagram shows it going to egr but i don't have an egr http://parts.nalleygmc.com/images/pa...07TC08-031.JPG



So anyone know where I hook this up? Any help is greatly appreciated. Thanks

 

The only thing Vacuum operated is the waste gate for you're turbo if they haven't done a turbo master or such to the truck
