Blower Power Transistor Test
SRS components are located in this area. Review the
SRS component locations
and the
precautions and procedures
before doing repairs or service.
NOTE: Before testing the power transistor, check for climate control DTCs.

Power Transistor - Test
1.
Disconnect the power transistor connector.
2.
Measure the resistance between terminals
No. 2
and
No. 4
of the power transistor. It should be about
1.5 k?.
If the resistance is within the specifications, go to step 3.
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.
3.
Reconnect the power transistor connector.
4.
Connect climate control unit 32P connector terminals No. 6 and No. 14 with a jumper wire.
5.
Turn the ignition switch to ON (II), or press the engine start/stop button to select the ON mode.
6.
Check that the blower motor runs.
If the blower motor does not run,
replace the power transistor
.
NOTE: A faulty blower motor can cause the power transistor to fail. Before replacing the power transistor, check the blower motor for binding, and
replace the blower motor if necessary
.
If the blower motor runs, the power transistor is OK.
