During our recent spate of icy weather my wife tried to start the wiper when the wiper arm was frozen in place. After that the intermittent wiper stopped working and the wiper would not park.
Another older symptom: periodically the wiper would stroke once upon activating the turn signal.
A search of this group yielded some ideas for a fix: loose wires behind the panel above the driver's feet; bad wiper relay; bad fuse. I saw no loose wires, replaced the fuse, and cleaned the relay contacts but the problem persists.
Ideas for a next step? A guy at the auto parts place suggested tightening a 15mm and a 13 mm bolt/screw somewhere on the wiper itself; I took the wiper covers off and saw torx heads holding that operating together but no screws or bolts. Is this worth pursuing?
Same guy at the auto parts place said "it may be the wiper motor".
Is this likely to be the stalk switch (given the earlier symptom of wiping upon turn signal), or the motor (since the intermittent stopped working when the blade was frozen in place)?
Thanks- Dave O
