OK, the wife brought the car home so I tried that.



It read a couple of codes about "No Message" in the IHKA2 module. When I reset them, it had no change on the symptoms, and the codes didn't come back.



When I active tested the blower in Foxwell, the only option was to run it at 80%, which it worked correctly when doing that. Then, I read the live data of the blower speed. The live data reported the command I was giving the blower through the HVAC panel, but the blower speed was stuck on one speed all the time.



I did find that pushing the defrost button through the HVAC panel runs the fan at full speed as well. But only on the defrost vents.



Does that tell you anything???
