Mitsubishi Repair Problems? Ask a Mechanic for Answers ASAP
Hello I will help,
Do you have a voltmeter?
Great, check for 12 volts at the white wire at the motor with it connected up. A straight pin can be slid along the wire to make contact inside the connector if necessary.
If you have 12 volts to a clean metal part of the vehicle then it is probably the power transistor.
How did the motor lock up? Has that been repaired?
To check the power transistor see if the black wire is grounded and that the red wire voltage changes as you change the blower speed.
Let me know what you find
