STEP 25. Measure the resistance at rear heater switch
connector E-21 <vehicles with rear heater>, rear cooler
switch connector E-17 <vehicles with rear cooler> or rear
A/C switch connector E-22 <vehicles with rear A/C>.

(1) Disconnect connector E-21, E-17 or E-22 and measure the

resistance at the wiring harness side.

(2) Measure the resistance value between terminal 1 and

ground.

• 2 ohm or less

Q: Does the measured resistance value correspond with

this range?
YES : Go to Step 26.
NO : Go to Step 28.

NOTE: Also check rear blower unit connector G-06 <vehicles
with rear heater or rear cooler> or G-22 <vehicles with rear
A/C>. If rear blower unit connector G-06 <vehicles with rear
heater or rear cooler> or G-22 <vehicles with rear A/C> is dam-
aged, repair or replace the connector as described in GROUP
00E, Harness Connector Inspection

P.00E-2

.

Q: Is the wiring harness between rear blower motor

connector G-06-1 (terminal 1) <vehicles with rear heater
or rear cooler> or G-22-1 (terminal 1) <vehicles with rear
A/C> and rear heater switch connector E-21 (terminal 7)
<vehicles with rear heater>, rear cooler switch
connector E-17 (terminal 7) <vehicles with rear cooler>
or rear A/C switch connector E-22 (terminal 7) <vehicles
with rear A/C> in good condition?
YES : The rear blower motor should operate normally.
NO : Repair the wiring harness. The rear blower motor

should operate normally.

STEP 28. Check rear heater switch connector E-21
<vehicles with rear heater>, rear cooler switch connector
E-17 <vehicles with rear cooler> or rear A/C switch
connector E-22 <vehicles with rear A/C> for damage.

Q: Is rear heater switch connector E-21 <vehicles with rear

heater>, rear cooler switch connector E-17 <vehicles
with rear cooler> or rear A/C switch connector E-22
<vehicles with rear A/C> in good condition?
YES : Go to Step 29.
NO : Repair or replace the connector. Refer to GROUP
