Power Transistor Test
Disconnect the 4P connector from the power
transistor.
Measure the resistance between the No, 1 and
No. 2 terminals of the power transistor. 11 should be
a b o u t 1 . 4 1 . 5 k Q .
lf the resistance is within the specifications, go to
step 3.
lf the resistance is not within the specifications,
reDlace the Dower transistor,
POWER TMNSISTOR
Carefully release the lock tab on the No. 4 terminal
(BLUI/EL) (A) in the 4P connector, then remove the
terminal and insulate it from body ground.
(To 12 V power
source on vehicle)
4. Reconnect the 4P connector to the power transistor.
5. Supply 12 volts to the No. 4 cavity with a jumper
6. Turn the ignition switch ON (ll), and checkthatthe
blower motor runs.
lf the blower motor does not run, replace the
power transrstor.
lf the blower motor runs, the power transistor is
oK.

Be careful not to damage the control unit or the
dashboard.
Install the control unit in the reverse order of
removal. After installation, operate the control unit
controls to see whether it works properly.
Run the self-diagnosis function to confirm that
