Headlight and Multifunction Switch Wiring Schematics Sign In

Does anyone have the wiring schematics for the headlights and multifunction switch for a 1999 Mercury Grand Marquis? I have my uncle's car and going to check grounds. I searched online and it seems most of the time the multifunction switch causes my issue tho. I want to check simple things first before I replace it. I got called back to work for a two week job so will only have a little bit of time each evening to check it out so won't have a chance to respond to my thread as often.

Thanks!

I don't know where you are reading that but you're in for a surprise here. This car uses a lighting module and they go bad all the time.
