06 gxp headlight problem

[dnfd737]

At random my headlights will turn off and I cant turn them on, my driving lights work and all other exterior lights work. I try the switch(as I have the automatic lights) and get nothing, it only happens after dark but if I turn the car off for 20-30 minutes they work again just fine.......any ideas as what I need to look for?

Usually, when an 06+ loses headlight, it's the DRL relay... they're like $17 on ebay. But that's not, to my knowledge, an intermittent issue. The lights should be permanently off.

So, I'm wondering if your DRL ambient light sensor (the bulb on the dash by the windshield) is faulty... whether there's a fuse issue, or whatever.

Are you saying your headlights work fine in daylight?

I hate DRLs, which is why i pulled the fuse on mine.

04+ doesn't have a DRL fuse I've looked for mine so I could disable the DRL's

Check the fuses on the inside Marine

Correction. 04 and 05-08 have different wiring diagrams. 05-08 have an HDM

04 have no DRL and no HDM. The way it should be. For some reason the douche engineers at gm decided to implement the HDM setup in the 05+ and besides taking out HID ballasts they fail often.

Turns out it was the HDM thanks folks.
