Converting from r12 to r134a
#17
Fords4Me, sorry to hijack the thread, but I'm getting ready to place an order for a big box of 4 seasons parts. The wiring harness you have listed - does that tie in to the compressor? I have identified the matching end of the harness coming from my firewall, but trying to figure out the wiring. All AC components were torn out of my truck before I bought it.

I have been told they getting ready to phase out R134.

From what I understand, R12 synthetics are hydrocarbon based and are technically illegal for automotive use (I've never seen an auto HVAC guy use it).
What you CAN do, is get your EPA section 609 certification online for a few bucks, and buy R12 off ebay and DIY with R12.
More expensive, sure. But legal.

I don't know if they made it to the bricknose trucks, but 1980-86 dealer installed air conditioners used hose clamps and hoses similar to heater hose but much thicker. They are easy to identify, since they use that gigantic York type compressor that mounts above the water pump. I pulled this one out of an 82 F-150 a few months ago.

I recently bought a '90 F250 and the AC didn't work. I decided to replace the entire AC system with the parts for a '95 that was designed for R134. New compressor, lines, Evap core, accumulator and condenser. The only part that wasn't plug and play was the Evaporator core. I had to modify the Evaporator housing with a dremel to get it to fit. I've heard that I went overboard and I've heard that this is the best way to do it. It was worth a couple extra bucks in parts to have a system that was designed for R134 and I knew was going to work properly.
