STEP 6. Check 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 blower resistor G-06-2 (terminal 1) <vehicles 
with rear heater or rear cooler> or G-22-2 (terminal 1) 
<vehicles with rear A/C>.
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 blower resistor G-06-2 (terminal 1) <vehicles 
with rear heater or rear cooler> or G-22-2 (terminal 1) 
<vehicles with rear A/C> in good condition?
YES : Go to Step 7.
NO :  Repair the wiring harness. The rear blower motor 

should operate normally.
