Rear Air on 2002 GMC Yukon XL Denali

The rear a/c in my truck is not cooling. When I turn the air on it blowes out warm air while the temperature is set on cool. What could be the cause of this? The front air works fine. Also What cost would be associated with getting this problem fixed?

cant give a price till you know the problem. it sounds like the freon level is low. the question os why and where did it go. freon does not evaporate, it leaks, get it tested for a leak and get an estimate. Roy

Ok,the plug that's located in the back of the compressor was broken and has since been replaced along with freon being added. New problem that I'm having is that the back air is not cooling; front air works great. Any suggestions?
