I have only cold air output from the heater regardless of the temp setting (up to 85). The water control valve is working properly and the 'out' pipe on the drivers side is hot.
I've read all the threads I could find here, and have not found any solution, nor a similar issue.
The troubleshooting in TRSM shows how to test/adjust the servo motor if all the above checks out. My problem is that the 'guide plate' shown in the TRSM looks Nothing like mine...see pic. Does anyone know how to check the position of this thing?
