Question
95 gmc suburban 350 engineclutch on compressor won't kick in, all fuses and relays are fine. replaced compressor with a guarenteed used one but clutch will still not engage. when trying to recharge systeem it only takes in a lil bit of r134a then stops. is it possible the orifice tube could be blocked not allowing fluid to run through system? If so where do I find the orifice tube on this vehiole?

Answer
Hi Richard

If your system has dual air then you need to follow the liquid line the one that goes from the condenser to the evaporator.  There you will find a connection the orifice is in there.  If you have a single unit system. then you will find it at the condenser outlet.
