Asked by Mar 10, 2015 at 05:05 PM about the 2010 Mercury Grand Marquis LS

Question type: Maintenance & Repair

Hey guys, I have a 2010 Grand Marquis that the wipers will not turn off. The off position is a little faster than the slowest intermittent position. Also the washers will intermittemtly go on and drain the washer fluid tank. Right now I have pulled the 30 amp fuse in the fuse/relay box under the hood. I need some schematics so I can troubleshoot. The switch (speed and push for fluid) I assume is what you are calling the multifunction switch feels good but that does not mean much. Any suggestions. Dealer said could not make it fail and wanted $400. I'm electronics engineer just need some schematics or info on replacing multi switch. Where is best place to get drawings? Thanks, Ron
