Purpose
The resistor controls the blower motor rotation speed.
Function
The resistor controls the supply voltage to the blower motor according to the fan switch operation, and adjusts the fan rotation speed (airflow volume).
Construction
The resistor is installed to the A/C unit.

A thin, card-type resistor has been adopted for weight reduction.
Operation
1. When the fan switch speed is set at 1, the resistor internal resistance increases and the blower motor applied voltage decreases. Therefore, the blower motor rotation speed decreases.
2. The resistor internal resistance decreases as the voltage applied to the blower motor by the fan switch increases in speed to 2, 3, and 4. Therefore, the blower motor rotation speed increases.

Fail-safe

Fuel-Filler Lid and Cap
WARNING
When removing the fuel-filler cap, loosen the cap slightly and wait for any hissing
to stop. Then remove it:
Fuel spray is dangerous. Fuel can burn skin and eyes and cause illness if ingested.
Fuel spray is released when there is pressure in the fuel tank and the fuel-filler
cap is r ...
