A\C Recharge

Hello,
I need help!

I had my very old car that runs great recharged yesterday(Saturday). It was cool at the end of last summer. The air was nice and COLD when I left the shop. Later on that day it was warm\cool. My neighbor looked at it and said the wheel like device on the compressor wasn't turning. Please forgive me for not knowing what the wheel device is called. I am a female so I have the right to not know.

I took my car back to the shop yesterday and when I left the wheel was turning and the air cold again. I was told that with the car being so old it takes a while for the air to kick in. I drove for about 20 minutes with the windows up and it should have "kicked" in by then I told them. I was told no leaks and compressor works fine. Well, this moring air is warm again and my neighbor said that the wheel isn't turning again. It's was over 90 degrees yesterday and today.

Any suggestions as to what is going on before I take it back to the shop again Saturday(work monday-friday)? Why did compressor wheel turn then stop? How did they get it to restart in the shop? Is the car just too old and need a funeral?

You may have a bit of an intermittent electrical fault that may need a spot of attention... Some of the US guys may know a little more about your car/ common faults

If the car runs fine and there are no leaks, then there is no need to take it out and shoot it..

Could be as simple as a "clutch gap adjustment" If you have a friend that is somewhat knowledgeable with cars, have him tap the front hub inwards (wheel) when the ac is on, and see if it pulls in and begins to work. If it does, the shop needs to adjust the clutch gap...Hope this helps..

PS: Be sure he/she uses caution around the spinning belts!! And please, don't use your hands, a screw driver will do just fine...

Find out what they did to make it start again. It probably has a big leak and they just put more refrigerant in to get it working for a short time. The delay thing is nonsense. If it is still charged, but works only intermittently, that is a different kind of problem but it can be cured.

Find out what they charged it with. Has someone converted it to use R-134a previously?

Also stop-leak may have been used. Stop-leak will ruin everything and often lead to having to replace the entire system. Don't let anyone put stop-leak into your A/C. It doesn't work.

Thanks so much for the reply. My neighbor hit the "wheel" with a screwdriver and it started to work!. It ran for about 5 minutes then stopped for a few seconds then started again, then stopped again, etc.., I will still take my car back because I don't know if this will continue tomorrow or what.

You really know the mind of a woman who just gas and go in her car? When you said don't use your hand I LOL. I thought about doing that while I was reading your post until you said that.

Thanks again.

The clutch gap needs to be adjusted to be smaller. It's a simple fix when you know how (exactly how depends on what type of compressor it is). Since it's not their money, many shops want to just replace the whole compressor rather than tinker with such things though.

I took my car back to the shop. I was told the clutch gap can't be adjusted and I would need a new compressor.

My car is old so I guess I will drive around with the windows down instead of spending the nearly $450 I was told it would cost to fix it.

Not sure about that exact model, but most non-GM compressors can be adjusted by removing shim washers under the clutch plate. Unscrew the nut or bolt in the center shaft and see if the plate comes off readily (some need to be forced off with special tools). Once the plate is off, look for thin shim washers on the shaft. Remove some of them and leave them out. Put the rest back together and you should have a smaller gap.
