Re: headlights shut off on bumps

Do that because I ended up changing my Headlight Multi-Function Switch Stalk. Took 20 minutes to change.

Re: headlights shut off on bumps

Re: headlights shut off on bumps

could be one bad connection sending a bad signal to the front control module or the control module itself?
