I did the r12 to r134a conversion and the ac blew cold for about a day and went out again. I don’t hear anything engaging when I press the ac button not sure if that’s relevant or not but other than that I can’t see or hear any other issues. Also worth noting I haven’t attempted to diagnose or fix the ac so it could be anything lolThat empty socket has no wires going to it off of that harness. Likely something for a different market.
Does anything not work on the truck?
