Blowing warm air

This seems to be a common problem with dodge vehicles. i was told it could be the condensor? it started out where just the driver side would be cold, and the rest of the vents would be blowing out warm air. I brought it back to the dealer twice where they recharged it and it would work for a short period. They told me it was the condensor, which would cost approx. $400 to fix because they would have to take the dash out. At the time, i was still under the extended warranty but it had to be clearly not working right if i put a claim in. naturally, after my extended warranty was up, it crapped out again and is just blowing hot air all around. I asked another woman i know w/ a 2005 Magnum SXT (6 cyl) and the same exact scenario played out with her A/C as well. Talking w/ other people, its happened w/ Dodge trucks also... anyone else experience this problem and do you have a fix? it's quite frustrating to stay the least...
