Front Park/Turn Signal Bulb Intermittently Inoperative (Check Bulb Operation and Replace Headlamp Wiring Harness, If Necessary)

Some customers may comment that the left or right or both front park/turn signal bulbs are inoperative. This condition may be intermittent and replacing the bulb may not correct it.

This condition may be due to a loss of contact between the base of the bulb and the socket.

Important: Some early versions of the headlamp wiring harness have a section of harness that is not needed for this bulletin. Prior to installing harness to headlamp, disconnect and discard this section.

Check the bulb for correct operation off the vehicle by using a 12-volt power source. If the bulb is found to be inoperative, replace the bulb with a 5702 KA Phillips bulb, P/N 15233607. If the bulb is found to operate out of the socket, then the headlamp wiring harness should be replaced. Remove the headlamp assembly for access to the wiring harness (refer to the Front Headlamp Replacement in SI, Document ID #1507485).
