2007 Pontiac Grand Prix. 3.8 V6.
Question: I am having difficulty getting my headlights to turn on when
I unlock the car. My parking lights & tail lights turn on but no
headlights. I have programmed the external lights to come on for
30seconds and even tried resetting it to off and then back on, but still
nothing. Please help!
Answer: You should be able to set that up in the personalization
section of the Driver Information Center (DIC). Your owner's manual
would have detailed instruction on how to do that. If they still aren't
coming on when you want them too, and you're sure the setting is
correct, you could possibly have a Body Control Module problem. You
would need the car checked to see if there are any stored codes in
the system. The headlights are automatic on your car, but that
shouldn't have any affect on the personalization aspect. We don't see
it often, but there have problems with the DIC before on your style
vehicle, but again it would need to be checked out at a dealer.
