2002 Chrysler Sebring: air conditioner..Every once..awhile..gets cold

Customer Question

I drive a 2002 Chrysler Sebring and my air conditioner has not been working. It consistantly blows air but the majority of the time, it blows hot air. Every once in awhile, it gets cold but not often. It also randomly alternates between blowing out of the vents, on the dash, and at your feet, without me changing the dial at all. I just think there are wires crossed or something. I need to know what I should do to get it fixed.

First of all you need to have the pressures checked in your system, It sounds like its low. Secondly, the dash vent problem may or may not be related, you may have another problem. Let me look at schematics and get back with you.Tim

So should I take it to the dealer and tell them what I think is wrong? How much does something like that typically cost to fix?

Expert:  Tim Mohr replied 7 years ago.
Yes take this bulliten to the dealer and explain your problem, If it needs to be reflashed, then its about a hundred dollars. But if it needs to be recalibated, it should be less.Tim
