REPLACING/A/C CLUTCH/COMPRESSOR

1995 Buick Lesabre

Air Conditioning problem
1995 Buick Lesabre 6 cyl Front Wheel Drive Automatic 130K miles

Re 3.8 L Engine. Getting noise from A/C compressor area and am assuming that either the clutch is bad or the compressor is bad. Since I am getting cool air from the vents, my best guess is the clutch or a bearing problem. In any event, I have to remove the compressor/clutch assembly. My question is, since I don't have a book, what is the recommended procedure for removing the compressor?

Too as I have said before, this is a two wire connector and one wire is light green and the other is kinda dark blue. There is electrical tape around the wires too, and I was wondering if this is some sort of test plug, since it is so short. I took the compressor out because the clutch was noisy and probably was going to fail altogether soon enough. I decided to replace the whole thing and I did notice that the one I took out was oiless and there was a nut missing from the middle stud which led me to believe that this was taken off before.

The wire colors are; looks like the same light green that is on the connector in question and the other wire looks white. The car iis a Limited edition and has climate control, which is automatic.

That leftover wire goes to a diode both manual and auto system has the same wire color attached to a diode

So, am I looking for a mating connector or someplace to connect that too or is that a connection they would use if I had a different system.

Both Manual or Auto should have that diode and its wired parallel to the clutch could be attached to the compressor housing with that length-Remanuactured who knows they didn't put one on to connect to. Or it just hangs there as pigtail wrapped with elect tape-I'm using Mit1 and Alldata auto references and still coming up with the same information.

Your are absolutely right! And so was I, to some extent. First of all, I'm missing a switch which goes on the back of the compressor and the reman doesn't supply it with the part and I should have taken the old one off of the one I turned it. Now how the hell am I supposed to know that? I thought when they reman something they would do the whole thing. You were correct in your analysis and I was correct that they just plug up areas and black paint over everything, but instead of using a plastic caplug, they use a metal plug and hold it in with a snap ring. The switch doesn't cost a lot (about $17.00), but it's the principal of the thing and it's something that the guy at the auto store should tell people. Anyhow, thanks for your help and I think installing the switch should solve the problem I'm passing all of this on to you with the thought in mind that it might help you in other case like this. Have a good day. Bob
