If the DRL is malfunctioning, it may cause the lights to remain off or not function properly. Common issues include blown fuses, faulty bulbs, or a defective module itself. To troubleshoot, check the fuses and bulbs first, and if those are intact, consider testing or replacing the DRL module.

Blinking headlights can be caused by various factors, including issues with the Daytime Running Light (DRL) module.

Proper diagnostic testing is needed to determine the exact cause.
The drl relay is located in the back of the glove compartment.
