Hi, I have 96 blazer and when I turn on the AC it is not cold. Does anyone know any probable causes of this problem, or how much it might cost to fix? Any help would be greatly appreciated.
Thanks

 

do you know how much refrigerant you have in your a/c? if you don't you would need to get a charging kit with a gauge from wal-mart orautoparts storeso it will show you how much you have.charge it if needed so.let us know what the outcome is.

 

If its not your refrigerant, it may be the electronic arm in the dash that swaps it from heat to A/C.
