Lost A/C?
two weeks ago, i suddenly lost my air conditioning. the blower just blows out hot air. I'm about to make a cross country trip, and really don't want to have the windows down the whole drive. What can I do at home to pinpoint the problem? I don't know about the whole A/C system, and i've heard that it should really be done by a proffesional, but i don't have that kind of money to blow on this, and I'd like to do everything i can before i take it to a mechanic. thanks!

In that case, your blend door is broken and is allowing air from the heater core to mix with the air from the A/C coil.

You can verify if it's the blend door by turning on the A/C and also turning the rear A/C on-if it's cold from the rear A/C,then the blend door is broken in the front. If not,then you've got other issues.

sorry guys i haven't had time to fix this, but just a quick update to the post...the vents vent HOT air when the A/C or heat is OFF as well...not blowing out, but venting. i don't think any air shoudl come out if everything is off...what could cause this?

how can i tell if this is the blend door, or the blend door motor? the motor will be 10x easier to replace, so i don't want to pull out the dash if its just the motor...getting ready to buy the part as soon as i can find a definitive answer! thanks for the help!

First thing first here. Does the a/c work? Is the compressor engaging when you turn the a/c on. You should hear a click and a slight change in engine rpm than should return. Do not go through all that hassle of a blend door. Make sure your a/c is working properly first. Yes, blend doors are a problem but it might be worth the $50 for someone to do an A/C test. Verify that first. Do you have rear A/C and heat? I assume you did what Alloro had posted. If you don't feel comfortable doing anything, have a shop diagnose the problem so you know what it is then you can tackle the repair yourself.
