Best Answer

The first thing I'd look at is the switch and then the connections to the blower motor.

Try bypassing the switch and see if the blower motor starts. Also, don't forget the fuse controlling the blower motor. Replace it with a fuse of similar size and see if that corrects the problem. If all else fails, just replace the blower motor unit with another. Go to the wreckers and you can get it for less than half price.

If by quit working you mean quit blowing, the things to troubleshoot are the blower motor, the blower motor resistor switch, or the blower motor speed selector switch. If by quit working you mean it only blows cold or warm air, the thermostat is probably stuck in the open position.

If the motor blower on a 2002 Ford van is no longer working how can you fix it?

First check the fuse to see if it is blown. If the fuse is good, then it is either the blower motor switch, blower motor Resistor Pack, or the Blower Motor itself. It can also be bad wiring. Apply 12 volts directly to the blower motor to see if it is good. If it is good and the wiring it OK, then it is the switch or resistor pack. I would bet on the Resistor Pack being the culprit. The switch rarely goes bad..
