A/C switches from dash to defrost by itself
#16
I'm having this same problem on my 03 super crew. Has anyone discover a solution? Min is currently switching all modes to defrost, though vent stays on the longest and switches back and forth with acceleration. Also, it has no problem getting hot but the ac compressor is not kicking on at all. Occasionally I will hear it vamp as if it is trying to but never actually kicks.
