Several ways to check for an a/c leak first visually inspect all components for traces of oil. to find stub burn leaks you can buy refrigerant cans with UV dye already in it charge and run the system until you see green on any components. if no leaks are found suspect the evaporator it is located behind the dash out of view. you can take it to a shop and they can check with a a/c sniffer to confirm. I would recommend after repair to have the system pulled into a vacuum to eliminate any moisture this can cause poor performance and parts failure happy hunting!

Intermittent cold air on a 2001 Grand Am GT (3400 engine)


When you say tinker with the A/C. what did he do??? Just want to make sure he did not hot wire anything to activate the compressor at the max position. If the system is low on compressor oil the compressor will not active to keep it from getting damage or low on R143A. Most place now will recharge the A/C system for $50.00 since they know that you can by a recharge kit for around the same price, but you need make sure you don't over charge the system or damage will occur. If you not familiar with the recharge procedure, have it recharged by a shop and if it's full then the problem may be a  pressure switch and that takes around 5 min to replace and i am sure the shop will let you know before they try to recharge the system by hooking up the gauges to read the pressure in the system. Good luck and keep me posted, be glad to help you get some cold air again.

Air conditioner turns on when car starts.


If only the AC indicator light is on but you are still getting warm air from the vents, this is not an issue.  Most newer cars run the AC compressor nearly all the time to prevent moisture accumulation inside the car.  Without the compressor running, your windows may steam up and hinder your visibility.

No A/C


open your hood and have somone in the car cycle the air and be looking at the compressor you should here an electric clutch kick in on the AC compressor you should also hear the engine RPM decrease and then increase if the clutch is engaging and still no cold air then you can go to any parts dealer or canadian tire depending on where your located and they have a kit with a hose to connect to your AC lines a leak sealer canisster and a refridgerant canisster provided your leak is not to big(like a rock peirsing your condensor) and you should be on your way to ice cold air this kit gives you all the stuff you will need aswell as directions hope this helps.
