Just finished a ton of work on my boy's '89 Sundance 2.5NA. Along the way, noticed a visible leak (light oil plus dye) where the suction line meets the compressor. Anyway, re-sealed and vacuum tested the system, then evacuated, then added 30.5 ounces of R-134a, as I've done lots of times in the past. Pressures are good (45 and 200 low/high) on this cool-ish 70-degree day; dash outlet temps are steady at 45-46 degrees F. So here's the kicker... While I'm getting nice long cycle times on the compressor (roughly 45-50 seconds on, 10 seconds off) in normal mode, if I put the system on recirculate the compressor does not turn off. I watched it run for 10 minutes straight, which was enough time for a light coat of ice to form on all metal parts of the suction line, all the way to the expansion valve. If I pull the harness for the low-pressure cutoff, it naturally cuts off. Bottom line is this: "normal" A/C is great, "recirc" mode keeps the compressor on all the time to the point of ice forming on the suction line. Never seen this one before. Any ideas? Thanks!
