I tried to do a search on this subject but not having any luck. I just purchased a 93 SC300 with a non functioning 134a ac unit. The AC compressor pulley seems to spin freely, but the clutch does not engage. The pressure in the system is good. Also replaced the AC Compressor relay, and checked the cigarette fuse. Any sugestions? Do I need a new compressor? Thanks

 

maybe should have searched in the engine forum, where this is going to

Just search AC** and in the engine forum. Might be some help in here.

Moved.
