So my driver's side headlight wiper basically just does whatever it wants now. After spraying the headlights (during which it sometimes moves and sometimes doesn't), it goes back to whatever position it feels like--sometimes the normal resting position, sometimes sticking straight up, and sometimes at the far end of its path.
I figure the motor must be bad, but wanted to confirm that I'm onto the right line of thinking before spending the time and money to replace that. Is that probably what's causing this, or is there something else I should be looking into?
(And no I don't want to get rid of the wipers; in fact I love them)
