2003 SLS A/C issue I have a problem with my A/C. When it is on the passenger side 2 vents blows ice cold air BUT the driver side is blowing air like it is the heater. Any suggestions? Re: 2003 SLS A/C issue -----------------------

if you have any codes - post them here -
ALONG WITH THEIR DEFINITIONS -
to diagnose AC problems -
you need to connect a quality set of guages -
then post BOTH the HIGH pressure readings -
and the LOW pressure readings -
along with the ambient - outside - air temp -
and the air discharge temp at the center AC vent -
with the temp set at 60* and a medium speed fan - Re: 2003 SLS A/C issue Is the drivers side "hot" or just warm? Ambient or warm is a sign of low refrigerant. Not quite low enough to set a DTC though.
