Was wondering if you have had problems with ac vent temps? my ac seems not blow cold as it should. the truck came from texas if that helps at all.... or is this how gm air works? can i do anything to change this? orifice tube or something alon those lines? even my gasser does not perform that well... but it performs better than my d max air..... :confused::mad:
