Directional Lights/Turn Signals Inoperative, Intermittent (Clean Turn Signal Switch Contact Surface)

Some customers may comment on intermittent/inoperative turn signal function. This condition may occur for either direction, but appears to be more prevalent on the left side. Due to the intermittent nature of this condition, it may be difficult to duplicate the customer's concern.

This condition may be caused by a voltage spike or arc as the turn signal switch opens. A voltage spike or arc may cause contamination on the switch contact surface. This contamination could interrupt the circuit conductivity.

DO NOT REPLACE THE FLASHER MODULE OR TURN SIGNAL SWITCH.

Perform the following repair procedure to clean the turn signal switch contact surface.

1. Disassemble the turn signal switch and carefully remove the grease on the contact surfaces.
2. Apply a thin film of dielectric grease, P/N 12345579 (in Canada, use P/N 10953481).
3. Reassemble and install the turn signal switch.
4. Verify that the turn signals are functioning correctly.
