I hope someone can give me some tips...my daughter-in-law's 2006 Grand Prix has a continuing intermittent electrical problem with the headlamps. It is a long story so to try to keep it short:
Replaced DRL relay about 9 months ago when at first her daytime running lights would not turn off when the car was turned off
About 3 months later the new relay fried (actually melted) and also burned the fuse block at the location it plugs into. I attributed that to a chinese made relay bought from NAPA and had to replace the whole fuse block. Purchased one form a local scrap yard...relays and all and installed it.
About 6 weeks ago she called me to tell me daytime running lights were not on while driving, and then actually no headlamps at night. I bought a GM DRL relay from a Chevy dealer and put it in...all worked fine.
2 weeks later she calls again..my lights are out. I had her plug in the old relay for kicks and they came back on.
That has now happened at least twice more, so she gave me the car to drive a few days.
Last night it did it to me, so I had the chance to work the headlamp switich and no matter what I did the low beams would not come on...only high beams. I didn't get home until late last night so I will look at it again later.
Right now I suspect some connector loose, but I am wondering if anyone has any other suggestions, or has experienced this and can give me some other ideas of what to look at?
Thanks!!!
