AC Clutch Don't Engage With 12V Jumped To Pigtail

[Ron]

Well, so much for its miraculous recovery. On the way to work it blew cold for the first few miles, then crapped out. When I got there I tried tapping on it but nothing happened. Probably a flaky coil?

Sounds like it. Pull it off and see if the connection from the pigtail to the winding needs to be re-crimped/soldered.
Measure the resistance through the coil itself if you can...

If you can pull the coil, I’ll send you a working one, for the usual price of...free.

is that the correct coil for her replacement compressor? oh wait..never mind.

Arrgh, I spent $25 on the clutch holder tool from Autozone but I still can't get the damn thing loose. It uses a 19mm nut and I can't seem to get enough leverage. I don't want to use the breaker bar or lean on the fascia too much in case I slip and break something that'll cost more than a couple hundred bucks to fix. Guess it's time to go back to the shop.

I checked the air gap with a spark plug gapper and it was .035-.038ish at the widest part, pretty much stuck against the pulley at the narrowest. Would that be enough to be causing these issues?

meh.. sounds like it has some miles on it but that electro magnet is strong. that will note cause it from pulling up to the pulley.

I agree. It is closer overall than normal....

Yes. The gap should be closer to the lower spec, .016. Because it is difficult to get the gap consistent all around, it will vary but .038 is more than double what you want. Take it apart and reset the gap.

Typically, there is one shim washer installed in the OE unit that can be removed to bring it back too the bottom end of the spec. It is a one time fix for an otherwise wearing assembly. Once the gap wears above the max spec with no shim, it’s time for a new clutch assembly or whole new compressor assembly at that point in time.
