Hi all,
2020 RAM 1500; trying to diagnose abnormal HVAC behavior so I connected my OBD reader, fired up AlfaOBD and I'm getting the following codes from the HVAC module:
B11C8
B1030
B11F2
B11F1
B11F3
B11F0
B11C8
These codes are all associated with temperature sensors, either in the ducts for the panels, or the floor, as well as the evaporator. Some are reported as hard fault and some intermittent. Seems awfully strange and coincidental to have all these sensors go out at the same time. Seems more likely that I have a short on a harness or simply that the HVAC control module is faulty, no? Where do I even find the HVAC control module to make sure I don't have a poorly seated connector?
Any and all help greatly appreciated!
Jon.
