Title says it all. It just blows air not any cold air, the AC holds its charge fine but I think it may have something to do with the wiring? I pulled my deck to get a number off the back but since then the AC button has not worked. Thus making the AC not work I guess.

 

Do you have power and ground at your A/C compressor?

 

check all the wiring

 

Yes, what would I need to pull to check the wiring? I have never dealt with taking the dash apart before and don't really want to **** something worse up.

 

is the compressor engaging correctly?

 

I remember assembling my Evo dash and finding something that wouldn't work. Turned out I forgot to plug in the electrical connector.

 

listen for the clutch to come on when you turn on the a/c. check lines for any colder parts of the line for plugging. (icing over). or you have a low charge. good luck.

 

How do you know the system has a full charge? Do you have an A/C recovery machine?

 

Start your car turn your a/c on high. Look at your compressor, what should be happening is obviously the pulley is spinning. In the center of the pulley is the clutch. It has three circles on in that should be spinning when your a/c is on. If that is not spinning then your ac isn't engaging and when you check the pressure its going to be normal (unless you have leaks) and it's not going except any more freon because the compressor is not cycling the freon. I just replaced my clutch literally 2 days ago.

 

I have had this issue after taking apart my AC controls to get in the dash so I could replace some bad bulbs.After re assembly my AC would come on but blow warm air and I checked compressor and it was fine ran diagnostics from the shop manual with a A/C Manifold Gauge and all was on point so I focus my time on the AC controls wiring that I took apart recently.
Turned out it was not a good connection with the harness and the AC controls,so I would say start there first seeing that it was working fine before you went into the dash.Good luck.

 

Because I have had 3 different mechanics tell me it holds it's charge fine. It's a brand new system lol.

Well I do need a new clutch but I was going to wait another month or so...thanks studio. That's going to be the plan while I try to get my new battery to fit XD.

 

I believe he's talking about the clutch in the AC compressor. Turn your AC on full and go look at the compressor which should be spinning. If it is not rotating in the center of the pulley try hitting it with a long wrench or anything you can stick down there. If it starts to spin after that then it's your AC COMPRESSOR CLUTCH. I replaced mine last summer because of the same issue. Ice cold now!! Hope that helps!

 

Your a/c clutch yes lol

 

a/c clutch eh...learn something new every day LOL. Thanks I shall give it a shot when I get a new battery that fits. Have no power right now.
