Question -
My daughter has a '95 Buick Century. The air
conditioner quit working.  When I checked I found
the clutch not pulling in.  I checked the fuse and it is o.k.  My question is, which relay goes to what?   If you could just identify what each relay goes to, I sure would appreciate it. Then I could check further.

Answer -
Your problem is more likely to be a LEAK in the A/C system of which has caused a LOW freon charge in the system. You need to have an A/C facility check for leaks FIRST.

Would this keep the clutch from even trying to pull in?  When you
turn the unit on, or off, there is no response from the compressor
clutch at all.

Answer
There is a PRESSURE sensor that monitors that amount of pressure in the A/C system and if the pressure gets to LOW the sensor will NOT let the compressor engage.
