Customer Concern: The low beam headlamps are inoperative.
Tests/Procedures: Pin test for power, out of the dimmer switch, on the Tan wire. If okay, pin test at the DRL relay. Power should be coming in on the Purple wire and out on the Tan wire. If okay going in, but not coming out, it has bad contacts in the relay
Potential Causes: Malfunctioning Connection
Daytime Running Lamp (DRL) Relay
Dimmer Switch
Defective Wiring

Tech Tips: The DRL relay is next to the hazard flasher on the convenience center.
