When i start my NA fairlane occasionally the rear demister will come on and the wipers will go back and forth about 4 times, what the heck does this mean, ive never seen it happen b4, also the trip computer will sometimes beep several times and display WRN where the date would be under the time?

Any suggestions???

hmmm i had something like this, very strange things like lights flicking, dials going crazy, ended up to be a short in the system somewhere, can't remember where, i'd say you'd have a short somewhere too, first place i'd look would be the steering column.

hope this can help somehow

maybe, but why the WRN flashing?
