Bright lights randomly go on and I have to wiggle the turn signal to turn them off

The dimmer switch is part of the turn signal arm. You will likely need to replace the switch. Might want to check that the wiring harness is properly connected. first.

Agree. Its either that switch or the wiring leading up to it.

Replace the "multifunction" switch.

I don't have one because I'm having the same problem with my 2006 Pontiac Grand prix.

I'm having the same problem with my 2006 Pontiac grand Prix almost everything I use my right turn signal my bright lights come on as well.

I've got behind 3 cops and this has happened. Not fun. Apparently it's the turn signal arm or the wiring... honestly easy to order the part yourself and do it.

Mine had the same issue, just started today found the problem. The wire connecting to the switch had gotten lose. Just had to pull the switch and reinsert the wire. It's the brown wire in the harness.

I had the same problem. On mine it was some excess grease that was on the switch was making contact with the high beam switch. I don't know how much a paper towel costs but it's gotta be a hell of a lot cheaper to wipe the grease off than. Hanger the switch.

I have a 2006 Pontiac Grand Prix Base and its having the same issue...

My 2007 monte carlo is doing this annoying crap I need help as well

Sounds like you and Logan both need new signal light multifunction switches.

So do I just change the whole trim signal assemble ??

Yes.

How?

It requires removal of the airbag and steering wheel. Find a youtube video that shows you how, or borrow a shop manual from your local library, or go to a Grand Prix forum and do some searching and you'll find guidance. Do your homework first to make sure its a job you're equipped to do. If not, any repair shop can do it. It's not a terribly expensive thing to have done.

Naa it don't,little more intense then putting in a car stereo having to keep going taking off the panels all to the left,but it was pretty easy otherwise.

problem solved, take out ur high beam light bulbs and get a light bar!

If I have to replace the turn signal switch will that also be the reason why my headlights turn in after the car is turned off it's a 2006 pontiac grand prix

Not necessarily. Why are you replacing the turn signal switch?
