air compressor not working
I have a 1985 500 SEL. The AC has always worked fine, including yesterday. I went to a restraunt for lunch (I about froze from the air before lunch), and when I came out, the air was hot all the way home (about 10 miles).
The fan is cycling just fine, but the compressor is not kicking in. The fuse seems OK, but if there is a relay, I am not sure which one it is. I noticed a couple of the relays are hot after running the engine a couple a short while.
When the engine is off, I can turn the front part of the compressor clutch just fine freely. Not sure if that is good or bed. I would think it should turn if the clutch to the compressor is not on.
I had the R-12 checked, and there is plenty of pressure; it is full.
I have not driven the car in a while due to dying the carpets, and want to take the family in it for easter.
