Question about 1997 Pontiac Grand Prix
Take it to a shop and have it professionaly replaced. You will not have the necessary machine/equipment to properly evacuate and recharge the a/c system after replacing the compressor.
If you do, please make sure they also replace the recevier/drier at the same time or you likely will have no warranty on the compressor and can very likely cause further problems later on.

i had the exact problem with my 2002 pontiac grand prix. i found a broken vacuum line that comes off the back of the engine. this vacuum line runs down the passenger side top wheel well in the engine compartment. it goes behind the battery mounts then traverses into the big wire harness just below the battery. the vacuum hose was broken there under the battery so i couldn't see it without physically tracing where it went. i took a little piece of rubber hose about the diameter of an aquarium hose and reconnected the hose. i now have cool air. you have to remember that this little vacuum hose keeps the climate control does open as well as close them depending on your hot-cold settings. this all occurs from the climate control knob inside the car. hope this helps. a real easy fix too...........phil

the egr value tubing also gets corroded with carbon. take tube off and use a wire brush to clean tubing. i talked with a mechanic and he said he has never seen an egr valve fail. most if not all egr problems are due to carbon build up in the egr tube. clean egr tube interior.

Yes, you can get a can of freon that has a blue hose with it, R134A freon. Look for the ac line in the engine compartment that has a blue cap on it, (the smaller line), not the red cap. Just push the connector on the hose on to the connection on the line. Have the car idling with all windows closed and the ac on at full blast. Do not turn can upside down or the liquid will flow into the system. While it is charging, shake the can every few minutes, or read the instructions on the can.
The best can to get is the one that has a small guage attached along with the blue hose.
