A/C compressor not working, 2000 Cadillac deville. Need to turn on to put Freon

You can rent a cooling system preasure tester at a parts store. These engines run so close to boiling that they must be able to hold presure or they overheat. Presurize the system and check for even the smallest leaks at all hose connections. I fought this problem for a long time before I figured it out.

First do you have a sterring wheel puller. Can't remove the steering wheel without one. Quite an involved job including snaking the electrical connector end through the steering column. I wouldn't recommend it to the novice

Sometimes, you have to start the vehicle, turn on the AC (Hi setting), and jump across (bypass) the low side pressure switch - to allow the compressor to start running and draw the freon in through the low side - make sure your fittings are correct and otherwise - Did you pull a vacuum on the system before you attempted to add refrigerant? I would highly recommend it - removes air and moisture....
