HVAC challenges
got the 944S back on the road.
the interior vents blow HOT air, so checked the HCV with mightyvac and it works. not feeling any vacuum from the connection to the HCV, so zip tied closed and hot air stopped.
and the AC is inop. started checking and cannot get the compressor to engage when I jumper the low pressure switch.
so, before I tear the dash out, wonder if anyone knows if both could be caused by the HVAC control module in the dash.
reading the Clark's garage notes, searching threads, and starting to dig into the WSM.
