A/C HELP!

My A/C has stopped working! It blows warm air in 3 of the 4 slots. The fourth slot blow's mildly cool air. What should I do? Am I out of A/C coolant, or what's going on? I don't know too much about the system. Please help!

Thanks.

The A/C refrigerant is too low - have it recharged & checked for leaks by your dealer.

Check the basics first. I had ours charged then drove to Burbank airport. FRIED on the way home because I forgot to press the Auto and A/C buttons.

If this happened suddenly there is probably a reason for it and it will probably happen again. Check to see if the condenser fan is working, if it isn't this can cause the system to overpressurize and purge refrigerant. Also check for leaks.
