Disconnected AC compressor

jwoodin84 · 11-15-2009, 08:41 PM

So I was having this issue where the AC was coming on for all settings, not just the defroster. Not sure why this was happening, but I figured I would go ahead and just disconnect the electrical to the compressor for the winter. Could this damage it in any way? I thought maybe I would plug it in once in a while and run the AC a little.

I have ran across tons of vehicles like that and most are still running to this day... so as from what I know.., this shouldn't hurt anything to disconnect wires from compressor....

as for the issue..., u may wanna check into the ac compressor switch near the evap..OR the actual switch inside the vehicle... either one can cause the ac compressor to stay on.....

just unplug it at the clutch. it will not hurt anything. it just will not come on. in the winter the a/c will help with defrost because it pulls out the moisture.

what year?

My_nightmare - how would I diagnose if one of these switches was causing the problem or not? Sorry I've never worked on this kind of issue before.

a 99 runs through the bcm so it could be bad or a switch panel. you would have to hook up a tech2 to find out.

Not sure how to diagnosis the issue, however there is a plug that goes into the receiver / dryer, unplug that and you should be all good to go. The plug is the sensor for the pressure switch / low coolant switch in the dryer, if its not connected the system should not work... I will post a picture of it later when I get home from work...
