When I turn my lights on my 2001 sunfire, they flicker on and off

When I turn my headlights on my 2001 sunfire, they flicker on and off. They do this for a little while then they eventually go out completely. When I turn them back on, they do the same thing.

2005 pontiac sunfire headlights flickering when lights are off, but stop when lights are turned back on.


You have a problem with the daytime running lights system. It could be the sensor, relay or body control module. The sensor is on the top of the dash, there is a panel up there that pops of to access it. (be careful because they do break easily). The relay is in the under hood fuse panel. The BCM is under the dash. It could be one of these or just a bad connection at the BCM,relay, or sensor. These are the reason it flashes. When you turn the lights on manually, it bypasses all of this. Fixing this, you need a volt meter and wiring diagrams.

Ok I have seen tons of posts about this issue with the Pontiac Sunfire, but no clear solution. I have a 2001 Sunfire the yesterday the Day Running Lights quit working. My passenger side head light will...


First check the R/S headlight fuse in the dash fuse panel (left side), second make sure the R/S low beam headlight bulb filament isn't blown, both these scenarios will do what you are saying. The DRL's work when both low beam lights are in series, thus only 6v going to each bulb at reduced brilliance. The high beam is a totally separate circuit controlled by the multifunction switch. The DRL relay is controlled by the Body Control Module, grounded there, and it will also illuminate the service vehicle soon light. It could also be a bad ground at G204. Its on the steering column support bracket.

2005 sunfire.. service light stays on and when you start the car it makes a clicking sound and the headlights flicker off and on. They should stay on but don't unless you actually turn them on.


the daytime runnig lights are inoperative, could be the module, relay or a bulb, usually bad wiring, go to cavalier daytime running lights on the web,, there you will get diagnosis directions

2001 Sunfire Headlight/Wiper Glitch


Check for a poor connection in the "ground splice" connector located at the battery box. It should be bolted to the corner of to box closest to the radiator. The negative battery cable also attaches to this bolt. One of the black wires in this ground splice connector is ground for both the wipers and the lights. This was the fix for my car!

It sounds like there is a short in the switch that turns the interior lights on beside the headlight switch. You might be able to get a switch after market from your local auto parts store. Possibly with it being an 01, it would be a dealer item. Try calling parts store/dealer to see if you can locate one. Hope this is helpful. Please rate. Thanks

Flickering Headlights and Dim interior lights


Definately an electrical problem....first off, check the battery and alternator connections to make sure they are tight. The problem has to be before the fuse box because the headlights and interior lights are on different fuses. It sounds to me like a loose wire, corroded battery terminals, or an alternator that is going bad. An alternator is a relatively easy and cheap fix. They cost about $100 and require removing a few wires, 3 bolts, and the serpentine belt.
