    • The blower motor adapter is a bundle of three wires located on the left side.

    • While the vehicle's ignition is on, push and pull gently on the wire connection.

    • If the blower motor turns on, you have identified the problem and following this guide will help you fix it

    • If the fan does not turn on, the damage may not be fixable without purchasing new parts.

    • For your safety do not grasp any wires you can not see. Do not attempt to grasp any wires that are not covered in insulation and/or electrical tape.

    • Turn off the ignition on the vehicle and proceed with the following steps.

    • There are two screws holding the adapter in place. Using a Phillips head screwdriver, remove both screws in order to remove and gain access to the adapter.

    • Be sure the car is completely off before unscrewing anything.

    • The fault typically occurs at the connection between the three wires and the adapter box.

    • Observe the damage and decide if electrical tape will be enough to hold the wires in place.

    • If so, using electrical tape, wrap the wires tightly until they are securely in place.

    • Replacement parts are available for purchase if the damage is beyond your repair capabilities.

    Check that you are getting power to resistor, if Not check Fan speed switch. If you are getting power to resistor, change blower motor. This would require a part or two & a test light but would answer question.
