Thread: 05 GP Air Conditioner Not blowing cold anymore

Hey guys,

I have an 05 Grand Prix that has just recently stopped blowing cold air when I turn the AC on. I had the car in the shop for some repairs recently and I'm wondering if the mechanic could have done something to mess around with my AC. I've never had a problem with the AC until he got his hands on my car.....never going to happen again....This may all be a big coincidence and if so, is it possible to repair the AC myself ?

The fan works, just blows warm air instead of cool. I believe I can start with trying to recharge my AC.

Any suggestions on supplies or if I should start diagnosing another place ?

Thanks in advance!

ok first off dont be doing this stuff yourself if you have no experiance! mechanics need an a/c license for a reason. that **** is extremly poisonous!

so first open your hood and locate your ac compressor, start the engine and get someone to turn on and off the ac while you look to see if the clutch on the pullie engages. look at the pullie and you should see the middle start spinning when on and not spinning when a/c is off. if it spins then your a/c compressor is usually ok. also when it engages you should see your rpm flutter for just a second.

if it does spin you have a leak and need to have dye put into the system so they can find out where it is and what needs to be replaced.

also what work was done on your car at the garage? if you think it could have been them

Only poisonous if you try to kill yourself with it, essentially.

Ok I didn't understand about 85% of that lol but it the poison symbol on the ac recovery machine at work.

i searched and found this thread. so thats why its being revived lol

but freon is actually heavier than oxygen so it sits low on the floor. if you ever leaked a huge amount in a room then you would want to make sure you stand up and not get on the floor. outside with a small amount you wouldnt have to worry about it. just dont blast the stuff directly in your face. the biggest thing about it is if you ever got caught its like a 10k fine.
