I own a 2001 Ford Expedition. Recently the heater fan would continue to run after I turned the vehicle off - the only way to stop it was to turn the heater control to off. This happened with both back and front heaters. I also noticed when I turned the vehicle off, removed the key, and opened the door the chime would continue as though I had left the lights on. Additionally my remote keypad for the door locks only works intermittently, I have replaced it's battery and reprogrammed it. This has stopped for now, but now the radio and windshield wiperes will not work when I change the transmission from park to drive. Any ideas what might be causing the problems? Thank you.

 

I've had this exact same problem.

Only happens after rain (or other moisture causing outdoor event).

I think the fix is here:
