Blower Power Transistor TestNOTE: LHD type is shown, RHD type is symmetrical.
|1.||Remove the passenger's dashboard under cover.|
|2.||Disconnect the 4P connector from the power transistor.|
|3.||Measure the resistance between the No. 3 and No. 4 terminals of the power transistor. It should be about 1.5 kW.|
|4.||Carefully release the lock tab on the No. 1 terminal (BLU/YEL) (A) in the 4P connector, then remove the terminal and insulate it from body ground.|
|5.||Reconnect the 4P connector to the power transistor.|
|6.||Make sure the BLU/YEL wire is completely isolated, then supply 12 volts to the No. 1 cavity with a jumper wire.|
|7.||Turn the ignition switch ON (II), and check that the blower motor runs.|
