Hello all,
The AC on my 1989 HJ61 suddenly stopped working after sitting for about 3 or so weeks. It has always worked well and fires right up in the spring. We added some R12 to it about 5 years ago and it has been great ever since...until today. Luckily my Dad has the necessary gear so after some fiddling around we extracted all the R12, vacuumed the system and recharged. We could find no evidence of leaks with the UV light (there was dye inside) and the vacuum held for 3 or so hours at 25(ish) in-hg so we thought it would be fine. Turns out it just does not work. Clutch kicks in from the dash switch but it does not seem to build enough pressure on the high side and the low side is too high (really almost equal during some checks. None of the lines or fittings really get cold. I read in another thread that there could be an internal leak causing things to bypass so I was just wondering if anyone had encountered this before I stepped up for a new compressor. The odd thing is that the compressor is quiet and gives no indications of failure.
