Blower Power Transistor Test

1. Remove the passenger's dashboard undercover.

1. Disconnect the 4P connector from the power transistor.

1. Measure the resistance between the No. 3 and No. 4 terminals of the power transistor. It should be about 1.5 kΩ.
   - If the resistance is within the specifications, go to Step 4 .
   - If the resistance is not within the specifications, replace the power transistor.
     NOTE: Also check the blower motor. Power transistor failure can be caused by a defective blower motor.
