Why do I have no power going to my blower heater motor on my Jeep Cherokee 1996?


Blown fuse, defective Blower Motor Resistor Pack, defective blower motor speed switch, (Doubtful), disconnected or loose wiring, and lastly a bad blower motor if it has power and will not run.

Easy enough to bench test the blower motor. Its accessed from the passenger side of the engine compartment. .Move the wash fluid reservoir out of the way (just unbolt it, leave hoses attached) and there are three 1/4" bolts holding the motor in place. Might need to pry it out after you have the bolts removed due to the gasket sealing.

On the bench, clamp the motor body in a vise such that the cage can be manually spun freely, then apply 12 volts to the connector.
