Arthur Digby Sellers Posted March 18, 2019 Share Posted March 18, 2019 When I first turn on the AC, the compressor whines for about 5-10 seconds then stops. It will then run without issue for a while and whine again. Quote Link to comment Share on other sites More sharing options...
DaveT Posted March 18, 2019 Share Posted March 18, 2019 If it is still working otherwise, Start looking for a compressor. Need to know the year & model of your car. Quote Link to comment Share on other sites More sharing options...

DaveT Posted March 18, 2019 Share Posted March 18, 2019 When I got my 86 back in 88, it came with A/C compressor noise. Someone had hack wired it so the compressor was always engaged whenever the heater controls were in any position except off. I replaced it, and never had the problem again, on any of the several similar cars I have had since. Point of mentioning this, is it seems rare that they fail. There are 2 versions. One where the compressor is next to the power steering pump, and the other, where it is near the battery. The compressors and mounting are different, so you have to get the right one.

1 Lucky Texan Posted March 18, 2019 Share Posted March 18, 2019 could it be belt noise? Quote Link to comment Share on other sites More sharing options...
