I recently bought a 1988 Ford F150. The Air conditioner did not work.
The first thing I did was pull a vaccum down -29 pounds and see if it would hold. It did for 30 minutes. So I was hoping if the compressor was good maybe just charge the system?
It was R12 and had never been converted. I took the plug off accumulator crossed the wires and compressor engaged. I added 3 cans of R12, less than full according to the specs but plenty to start feeling cooler. I did plug the Accumulator back up and the compressor was kicking on and off as if it was low.
But the temp at the vent was blowing 96 degrees.
Any ideas on where to start with the problem? Looking for an order of processes or a starting educated guess.
Thanks.
