I have a 2003 GMC Savana High Top conversion van, The blower motor continues to run with the vehicle is completely shut off. What part needs to be replaced?
The blower motor resistor is bad. They will do all kinds of goofy things when they go bad. Mine did the same thing with the key out of the car, blower motor would run. It took 5 resistors until I got a good one.
