Test
Dip the sensor in ice water, and measure the resistance
with a digital multimeter. Then pour hot water on the
sensor, and check lor change in resistance.
Compare the resistance reading between the No. | 8nd
No. 2 terminals of the evaporator temperature sensor
with the specifications shown in the following graph;
resistance should be within the specifications.

1.Disconnect the 3P connector from the oower tran-
st$or.
Carefully release the lock tab on the No. 2 terminal in
the 3P connector, then remove the terminal and insu-
late it from body ground.
Connect a 1.2 - 3.4 W bulb between the No, 1 and
the No,2 cavity on the 3P connectol
Reconnect the 3P connector to the power transistor.
Turn the ignition switch ON (ll). and check that the
blower motor runs.
a lf the blower motor runs at half soeed the oower
transistor is OK, replace the heater control panel.
. lf ths blower motor does not run at half soeed,
reDlaca the Dower transistor.
