Question about 1996 Buick LeSabre
Ok, I bought this car from a friend and she said one day last summer the AC just quit one day. I checked the fuse inside the car, the maxi fuses under the hood and replaced the ac relay...all good. The compressor still will not kick on. I bought a R134A Kit at the auto store. Now I have not put any in yet. I did hook up the hose with the guage just to see if there was pressure in the line (making sure it will even hold pressure that there were no leaks so to speak). It is reading about 85 psi with the car turned off. I know that once the clutch engages, the pressure will drop, but as of now it is in the red and the clutch will not engage. Any Ideas? I would like to "jump" the compressor to engage it, to see if the compressor even engages, but I have no idea what wires to jump. There is a plug in the back with 3 wires, I am taking that it is the pressure sensor and a plug on top between the pulley and the compressor with 2 wires, a green and black.
No this is a high side cutt out for compressor,,,,low side pressure switch is what ur looking for look on dryer it should be ther jump them 2 wires,if it kicks on add freon 85 on low side not running is about out but if the ac does work and gets cold plug sensor back up and if it doesnt work,unscrew switch and go blow it out with a air hose (compressed air)and tap it around /put it back and try it /if it doesnt fix it buy a new switch

The first thing to check is if there is enough gas. The compressor will not work when the gas is low. There is a small inspection glass on the line. This needs to be clear. If you see streaks or bubbles means the gas is low. Never mind the pressure or wiring for now, Add one can of gas and this should get that first part done.
