2003 Suburban Air Conditioner Problem

[JMZink]

I have a 2003 Suburban K1500 LT with 3 zone climate control and rear air. It was working perfectly until last week when it would start with cold air front and rear and then it would start blowing warm air. Today it will only blow warm air.

Checked fuses, all were good. Belt was good. Check to see if the clutch was engaging, it would not. Have not checked pressures yet, but will do that in the morning. No noticable leaks. I would really like to have my ducks in a row before taking it in to get check. I suearched the forums for clues but found no real good ones. THanks for any help you can provide.

if it was working then over a week or less the unit slowly failed to cool you must have a leak..check a fittings / condenser coils ..

with the compressor not running this would be due to low pressure..

most likely you have a leak, related to freon.
