2004 Chevrolet Monte Carlo Q&A
2004 Chevrolet Monte Carlo Question: how do i repair headlights that go out while driving?
You may have a faulty headlight dimmer switch witch is part of the multi-function turn signal switch on your 1004 Chevrolet Monte Carlo. The best way to confirm this would be to test the headlight system using a test light and the proper wiring diagram. - Oakman
