Compressor clutch was cycling on/off but AC working good - took to shop and they charged system and replaced the low pressure switch. Now AC runs for awhile then clutch disengages, and does not come back on unless AC turned off for abit - sometime have to shut car off and then back on. Won't happen ...

1997 960 - I can hear the the AC clutch cycle on/off every 2-3 seconds when I'm sitting in traffic (loud click) - when driving I can't tell if it is doing the same or not. I read this could be due to low freon - it was low and I had it recharged. The AC works great but the clicking still occurs. Any...
