my front ac blow ice cold the back ac dont it blows hot air any one know whats up with that

 

Does your ac controls switches feel different at all?

 

o never mind that woulnt cause the back to blow hot. i think its the expansion valve, in the old style trucks like the burban i belive they have 2 expansion valves one for the front and one for the rear sounds like the rear one got frozen or cloged somehow i.e. no freon getting to the evap.

 

replaced the expansion valve still hot

 

did you check for leaks?

 

dot know then man i would do some searching on google sure someone else had it happen

 

thanks for the info
