Question about 1988 Buick Regal
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.

SOURCE: replace AC compressor clutch
you will need to have the small tool kit that comes with both tools for pulling and installing clutch assembly. Check with Autozone and see if they have it in their tool loan program.

Difficult to describe, but I will give it a try.
Inside the driver's side fender, close to the front of the car, there is a bracket that is held in place by one bolt, but which has a short horizontal bar as part of it which has two large clips encircling two cylinderical devices which have wires clipped into them at the bottoms. The one closest to the front (radiator) is the compressor clutch relay. The other one is the condenser fan relay.
Hope this helps you find it.

to prevent damage to the air conditioning system there is a "low pressure switch" located on the condenser near the low pressure hose (large one) .. if the refrigerrant (R134A) gets too low then the clutch will be blocked from activating by that switch .. you can have your system tested and recharged or you can do that yourself .. the R134A is available at auto parts stores .. some come with a gague that is required for proper charge .. if you dont already have a gage then yoiu will need that one ... recharge kits often come with instructions .. other less likely but possible problems could be a fuse or bad AC clutch relay. sometimes damaged wiring or bad clutch will be the problem but much more likely just low fluid ..

SOURCE: AC is not working, compressor
the ac to work the car has to has to be charged fully with freon. if it is low or is a malfunction on the system, it is not going to engage, another thing is also to check the fuse for the ac and relay,the best way is to see how much freon the system has and go from there
