Chevrolet Repair Questions? Ask a Mechanic for Answers ASAP
HiCustomer Thank you for asking your question on Just Answer.
Can you tell me a little more about the symptoms?
Do the lights have problems only during the day (DRLs flash), & does this happen when the switch for the headlights is turned on?
If the lights are working, including the DRLs, then it is probably just a loose connection between the DRL control module and the instrument panel. I would suspect that the loose connection would be at the control module, which is below the driver side of the Instrument Panel, near the center console.
I would suggest that you (or your husband) take a look at the connector on the DRL control module, especially Pin G (shown in the diagram below). I believe this pin provides a Ground signal to the light on the dash.
Here is the procedure to replace the module, so this should let you know how to get to it, and the schematic, if you need it.
Refer to Fastener Notice below.
Tighten the daytime running lamp module bolts to 2.5 N·m (22 lb in).
I hope this helps. Please let me know how it goes or if you have more questions.
Take Care, Greg A.
