Question about 2000 Pontiac Grand Am GT
Hi, if the Compressor is running and you can see and hear the clutch on the front of it engage, the 30 amp fuse is good and not blown. Have someone in the drivers seat, in park, brake set turn the a/c on after the engine is already running. You stand there and watch while they turn it to full cooling. You should see and it the part on front of the compressor click and come on and stay on. If it does not come on, this is an indication that there is no freon in the unit.The pulley will turn with the belt, but the plate in front has to come on for it to pump. If it goes on and off cycles like that, its low on charge and is cycling on the low pressure switch. Check these things I have said and keep me posted. If it does cycle on and off, you can pick up a can of R-134A with hose and gauge at auto store and charge through the low side. If its out, it will take about 2-12oz. cans. Let me know how it goes. Please be kind when rating if I have been of help to you. I wish you the best!
