Has the harness to the blower motor been checked along with the heater control panel?
Customer: replied 4 years ago.
No. How would I check those?
Expert:  Cardoctor74 replied 4 years ago.
Ok unplug the harness and check if there are any melted wires or connectors to the blower motor along with the blower motor resistor.Check the harness also for power and ground.As for the heater panel it will need to be removed and checked for burnt or melter spots on the printed circuit board.These are what you need to check next .
Customer: replied 4 years ago.
I don't recall seeing anything that looked burnt. The resistor that I replaced had some corrosion on the contacts.Where exactly is the heater panel?I'll check later today when I get home.

Thats the actual panel that you can change the temperature and blower motor speeds I have seen these short out quit a bit actually.Was this replaced already?
Customer: replied 4 years ago.
Yes, I had to remove the 3 knobs, pop off the panel above the ashtray unplug the harnesses and remove and replace the switch.
Expert:  Cardoctor74 replied 4 years ago.
Ok so that entire panel was replaced correct or just the switch?
Customer: replied 4 years ago.
Just the switch. I just plugged the harnesses back after I replaced the switch. Is the control panel where those harnesses are connected?
Expert:  Cardoctor74 replied 4 years ago.
Yes thats what shorts out there is a printed circuit board that overheats and causes this issue.I would have this checked next.Hoped this helped.Positive feedback and bonuses greatly appreciated.
