Engine Size: 4.2
Refrigerant Type: R134a
So the compressor is trying to lock up at 150K miles.
It has Auto Climate Control (which I hate) and dual left-right temp controls (which I also hate).
I'm planning on replacing the Compressor, Comdenser, Reciever/Drier, orifice tube at least.
Looking at the a kits site I see several compressors and compressor kits, but no real descriptions to tell them apart except the prices. I want a good NEW compressor, but don't care to spend big bucks. Recommendations?
Also, does the fancy climate control mean a fancy Reciever/drier and/or orifice tube? Looking at rock auto.com shows some ad delco parts that seem unique, but hard to tell from their descriptions.

If you have a receiver dryer- you have a TXV (expansion valve) - not an orifice tube- I'd replace with OEM supplier- A/C Delco.
The number one A/C diagnostic tool there is- is to know how much refrigerant is in the system- this can only be done by recovering and weighing the refrigerant!!
Just a thought.... 65% of A/C failures in my 3200 car diagnostic database (GM vehicles) are due to loss of refrigerant due to a leak......
