I'm having a weird electrical problem that only shows up after a car wash. First it started with the "Check Tire Pressure Management System" indicator going off. Now I've noticed that I can't fold the mirrors in or adjust the mirrors. It isn't a fuse, as it will work occassionally. I'm hoping it will clear up again as it has in the past once everything dries out. I suspect water is getting into a plug, etc. Any suggestions on where to start looking? 2013 model year.
