A/C blows, but it is hot

It is getting way to hot down here in GA. It was bordering on 100 today. My A/C works but it blows hot, hot air. Argg it pisses me off. What is wrong? Do I just need more A/C Coolant or is the compressor ****ed or what?

Re: A/C blows, but it is hot

First raise the hood
then start car
then turn on AC
then go to front of car and see if the AC pump is actulally turning(not just the pulley but the hole front part)
if it is then the problem is in the heat/air blend door
if it isn't the AC unit needs repair/recharge.

Re: A/C blows, but it is hot

has the car ever had the a/c recharged? If the a/c compressor is working my bet is that is just needs to be recharged.

Where do you find Freon cheap? it's like $50 out here,and you have to be licensed to get it.

Re: A/C blows, but it is hot

that's probably because you're in cali and they're strict with pollution, out here you can purchases r-134a at the local pep boys.

My bad,I was thinkin' R12 not 134. Yeah 134 is like $5 a can so it's not to bad,but 134 isn't really Freon.

Ya r-12 is priced insanely because they taxed the hell out of it due to all the damage it does to the environment. Why do you say r-134 isn't freon?

They are both refridiants,but two seperate gases. I don't know the chemical equations for each,but I do know that freon is a type of gas and 134 is a differant type. Kind of like Oxygen and air,they both work,but are differant.

Re: A/C blows, but it is hot

You should find the place were the refrigerant is leaking from, it's a closed sytem, and if you don't it will only eventually leak out again.

I'm aware that they have a different make up however i always hear everybody refer to 134a as freon as well, just curious to see what the difference is.

It's kinda like a vacuum bottle,everyone calls them a Thermos bottle. Only Thermos makes a Thermos bottle,the rest are vacuum bottles. Not being a smart@ss hear just making a point.

Re: A/C blows, but it is hot

You only need a very small amount of R-134 in the system for the A/C clutch to engage.

You should be looking for a broken wire at the A/C compressor's connector. (If your lucky, that's your problem)

If the connector looks good, trace the two wires upwards by the throttle body. With the A/C controls on, test the 2 wires for power and ground.

If that checks out, I would suspect a leak in the system or faulty compressor.
