I know, on the scale of critical issues, this ranks fairly low, but I've managed to get everything in order except for this one thing...my passenger-side headlight wiper is acting hokey. About half the time when I do a wash cycle, the pass. side headlight wiper will not park, but will stay in the up position. Then, when I start the car again, my windshield wipers will cycle once (!), and the headlight wiper will then park properly. Other times, this doesn't happen at all, and the process goes normally. I already replaced the headlight wiper motor once about six months ago (I really enjoy using them!) but I'm thinking maybe something else could be wrong, before I spring for another new motor. Thank you for any thoughts.
