BLOWER RESISTOR
INSPECTION
1. REMOVE GLOVE COMPARTMENT DOOR (See page
BO−76 )
2. REMOVE BLOWER RESISTOR
Disconnect the connector and remove the 2 screws and blower
resistor.
3. INSPECT BLOWER RESISTOR RESISTANCE
Measure resistance between terminals 1 and 4. Standard resistance: 1.8 − 2.2 Ω
If resistance is not as specified, replace the blower resistor.

INSPECTION
1. REMOVE THERMISTOR
2. INSPECT THERMISTOR RESISTANCE
(a) Place the thermistor in cold water, while varying tempera-
ture of the water, measure resistance at the connector
and at the same time, measure temperature of the water
with a thermometer.
(b) Compare the 2 readings on the chart.
If resistance is not as specified, replace the thermistor.
3. REINSTALL THERMISTOR
