Hello All,
I have a 4520C and as of late I noticed my cab heater doesn't seem to blow warm air. I have messed with the blender control on the HVAC panel and that doesn't do anything and I do have the heater switch on and it is red. Does that switch control some sort of solenoid to open a coolant valve to feed the heater core?
I also must have some sort of short in my cab ceiling as my courtesy light and radio fuse blow as soon as I change it. That happened last year and didn't impact the heater's function.
Any suggestions what to check?
Thanks
