Hey, Do any of you guys running Blazers and Jimmys in the Desert South West have working air conditioners in your rigs, and do you find they are adequate for cooling in full-on Summer?
Region would be Arizona, New Mexico, Texas, Nevada and non-coastal California.
My '71 GMC Jimmy once had Production Air but the PO let it lapse. I bought the truck in '95 but was not interested in A/C, so I took off most of the components, and stored them for later use. In the following decades, that stuff got lost. I would have to start from scratch. I still have the Controls, A/C heater core, and an A/C dash, but compressor, brackets etc. are long gone.
I'm in Tucson, and high summer temps here can run in the teens. With the voluminous 5 pax cabin of the K/5 type, can that space even be cooled enough?
Looking for opinions and experiences. Probably restoring an OEM 1971 Model Year A/C system might be impossible now, with the refrigerant changes. So what would be good options?
