Headlight problem, need help
#12
I would suggest getting it checked for codes. Mine has the same problem and it is either the Fog lamp switch or the CCM (climate control module)/ this is your a/c control head. I'm going to check mine here in the next week or so. Let me know if you can get it check for codes and what the codes are. I could post up the diag. flow charts for the codes so you could fix it.

Yes it will. It'* not stored in the pcm. I may have misinformed you on where the code may be set if it is th fog light switch or DIM like mine is. It will be in the DIM-Dash Intergration Module,IPM-Insturment Panel Module this is not you insturment cluster. Both of the module are considered a body control module of some sort by GM.
Edit: if it is a twilight sensor the code will probably be stored in the CCM as stated above.

I have had the same thing happen to me but I have decided that it is just some wierd cut-off point for the twilight sentinel. Like the posts previously, it happens only in Park and in situations where there is a questionable amount of light/dark. Mine does it in the garage sometimes depending on how much morning sunshine there is and it also does it at drive-thrus (especially Taco Bell) when I have to put it in park because they are taking too long. I don't see it as too much of a problem since I by-passed my DRL'* the first week of owning mine. I wouldn't worry too much, but that'* just me.
