I've noticed lately that the wipers on my 2003 Focus ZX5 (North American) are behaving strange. If I turn them off in mid-wipe, most times they simply just stop whereever they are on the window. They don't finish their current wipe and go back into the hood.
Same thing with the "one touch" wipe. If I flick the switch, the wipers usually stop where I let go of the wand, without finishing the wipe.
If I bump the car however, they then finish and go back into the hood.
Next time I'm in the dealers I'm going to get them to check this (and hope I can duplicate the problem) but I was just curious if anyone else had the same issues.
