The blower motor is a powerful fan that forces air through your Dodge's cooling system, driving either warm or cool air into the cabin. When the blower motor fails, that air can no longer circulate, causing the climate control to not function properly. Symptoms of a failed blower motor include feeling insubstantial or no air flow from the vents even with the fan setting on high. Replacing the fan with a new one remedies this problem.
Tools Used: Wrench
Install Heater Core
Raise the hood and disconnect the negative battery cable. Loosen the nut on the cable with a wrench. Slide the cable off of the terminal. Place the cable in a position where it no longer makes contact with the battery stud.
Open the glove box and empty out its contents. Firmly press in on the sides of the glove box to disconnect the top portion from the tracks, allowing it to extend beyond its normal range of motion. Allow the glove box to fall towards the floor, exposing the mechanics behind the dash.
Unplug the wire harness connector on the blower motor, which is in a plastic case connected to the heater housing. Look at the replacement part for reference. With a screwdriver, remove the three screws holding the blower motor to the heater housing. Pull the motor out through the glove box area.
Reverse this procedure to install the replacement motor. Reconnect the negative battery cable, firmly tightening the nut with a wrench.
