Test G: The Blower Motor Does Not Operate Correctly
PINPOINT TEST G: THE BLOWER MOTOR DOES NOT OPERATE CORRECTLYNormal Operation
Under normal operation, ground for the blower motor is supplied by the blower motor resistor or blower switch through circuit CH430 (VT/OG). In LOW, the resistor is grounded through circuit GD123 (BK/GY). In MED-LOW and HIGH, the resistor is grounded to the blower switch through circuit CH428 (GN/WH) and CH429 (GY/BN). In HIGH, the blower motor is directly grounded to the blower switch through circuit CH430 (VT/OG). The blower switch is grounded through circuit GD121 (BK/YE).
This pinpoint test is intended to diagnose the following:
- Wiring, terminals or connectors
- Blower motor resistor
- Blower motor switch
