my intermitten wiper on 94 E420 is acting up. it sometimes works and it sometimes does not work. also, i've been noticing that the interval between the intermitten wiper is sometimes random.
i got the car to a dealer to check it out. they couldn't pin point the problem but recommended that i change the relay and the wiper/signal switch for an estimate of 800 bucks. no thanks. i'll let other people to rob me.
does anyone have a clue as to what might be going on?
