I'm aware of the condenser and evaporator issues that these trucks have. However, I believe I'm having a different issue in my truck (2014 5.3 LTZ). In the mornings the ac works fine, its cold and i use it on minimum fan speed. But starting a couple of days ago, in the afternoons (~100F), the air coming out of the vents is warm and the cabin dosen't cool down. Any idea what may be causing this?
I already checked the cabin filter and the ac compressor is kicking in (so i assume its not a freon issue). So not sure what else to check. Any advice/help is appreciated.
