As an ASE, Chevrolet, and Cadillac master Technician for almost 15 yrs, the best way to search out this leak is to add R134A compatible tracer dye to the system when you charge it again. Sometimes you will be able to find the leak within 24 hrs or so of running the system, you need to circulate the dye throughout the system, it will find the leak area as the refridgerent is leaking out. You will need to use special high intensity UV light with a special pair of glasses in order to see the tracer dye. Most reputable shops are useing this method. If I had to guess as to which areas to look at most closely, it would be the front seal on the compressor and the evaporator. Most GM compressors are notorious for leaking at the case halves(if that style) and the front seals. Word of caution, only allow a professional to try to replace the front seal on the compressot as there are several special tools needed to perform this job. As for the evaporator, check your vents, both dash and floorboard and your drain tube coming out the firewall on the passenger side for traces of the dye. This will hint at a leaking evaporator. Grand Ams are bad for these. Good luck in your search.

That must be the curse of the Pontiac Grand Am. I had air conditioner problems with 1997 model that I owned. I experienced the identical problem that you did.The service advisor at the dealership told me that the only cure was to replace the compressor. I replaced the compressor, all the hoses and belts. I did not have any other trouble after that. I am so glad that it was still under warranty because those parts were expensive coming from the dealer.

Obviously you have a leak. The question now is where? Take it to a specialist, not your average mechanic, have him run a vaccuum test first. This will do 2 things - it will remove everything from the system (including bad gases that have leaked in) and will tell you if your system is tight. If it does not hold vaccuum then it is not tight. The intake hissing may help pinpoint where the leak is. If not the next step is a flourescent dye that glows under blacklight. Once the leak is found then the job gets easier.

By your description you obviously have a severe leak somewhere in the system. As a mechanic for a long time I can tell you the best way to find a leak is to have fluorescent dye added to your system the next time you have it charged and then within a few days have it checked again using an UV light which most good shops or dealerships should have. Within days if you have a leak it should be very easy to find by this method and then repaired.good luck.

You can have a bad blower motor. I know that the dealer tens to be expensive but your best bet is to take it to the dealer.
