1994 sl500 A/C not working
My A/C is not working I turn it to low temp and hit blue button on center vents and clutch doesn't come on.Fan does work fine I checked at Schrader valve and freon does come out and I checked cluth on compressor it turns so I was told to check high low switches at dryer.is there a fuse just for the A/c clutch ?

Out Of Control!!
You need to put a set of gages on the system to learn the amount of pressure the compressor is making---bla bla bla--what's the pressure--if it's less that 196 you have a leak or the compressor is shot!

1994 sl500 charging system
None of the fuses under the hood are blown..I checked voltage at battery when car running its at 11 V so alternator not charging.I see you can. Replace regulator in alternator is it poss this could be problem? I guess I need to check voltage to alt if it is present the it must be regulator ???
