Test R: The Auxiliary Blower Motor Does Not Operate Correctly Using The Front Auxiliary Blower Motor Switch

PINPOINT TEST R: THE AUXILIARY BLOWER MOTOR DOES NOT OPERATE CORRECTLY USING THE FRONT AUXILIARY BLOWER MOTOR SWITCH

Normal Operation
Under normal operation, the blower motor is provided a ground from the resistor through circuit CHA08 (GN/OG). The resistor gets a ground from the front auxiliary blower switch, depending on selected speed, through circuit CHA06 (YE/VT), CHA07 (BU/GY) or circuit CHA16 (BU).

This pinpoint test is intended to diagnose the following:
- Wiring, terminals or connectors
- Auxiliary blower motor resistor
- Front auxiliary climate control assembly
