- B1 CHECK THE MULTIFUNCTION SWITCH
- Key in OFF position.
- Disconnect: Multifunction Switch C202c.
- Carry out the multifunction switch component test. Refer to COMPONENT TESTING for component testing.
- Did the multifunction switch pass the component test?
- Yes : GO to B2.
- No : INSTALL a new multifunction switch. REFER to STEERING COLUMN SWITCHES .
- B2 CHECK CIRCUIT 938 (BK/LG) FOR AN OPEN
- Measure the resistance between multifunction switch C202c pin 5, circuit 938 (BK/LG), harness side and ground.
- Is the resistance less than 5 ohms?
- Yes : GO to B3.
- No : REPAIR the circuit. TEST the system for normal operation.
- B3 CHECK CIRCUITS 56 (DB/OG), 58 (WH), 61 (YE/RD) AND 63 (RD) FOR SHORTS
- Disconnect: Windshield Wiper Motor C125.
- Using the following table, measure the resistance between windshield wiper motor C125 harness side and ground:

RESISTANCE REFERENCEWindshield Wiper Motor C125 Ground pin 10, circuit 56 (DB/OG) ground pin 11, circuit 58 (WH) ground pin 1, circuit 61 (YE/RD) ground pin 9, circuit 63 (RD) ground - Is the resistance greater than 10,000 ohms?
- Yes : GO to B4.
- No : REPAIR the circuit(s) in question. TEST the system for normal operation.
- B4 CHECK FOR CORRECT WIPER MOTOR OPERATION
- Disconnect all wiper motor connectors.
- Check for:
- corrosion
- pushed-out pins
- Connect all wiper motor connectors and make sure they seat correctly.
- Operate the system and verify the concern is still present.
- Is the concern still present?
- Yes : GO to B5.
- No : The system is operating correctly at this time. Concern may have been caused by a loose or corroded connector. TEST the system for normal operation.
- B5 CHECK THE WINDSHIELD WIPER MOTOR
- Key in OFF position.
- Disconnect: Windshield Wiper Motor C125.
- Carry out the windshield wiper motor component test as outlined in this article.
- Did the windshield wiper motor pass the component test?
- Yes : The system is operating correctly at this time. Concern may have been caused by binding or incorrect pivot arm adjustment. REFER to WINDSHIELD WIPER BLADE AND PIVOT ARM ADJUSTMENT . TEST the system for normal operation.
- No : INSTALL a new windshield wiper motor. REFER to WINDSHIELD WIPER MOTOR .
