at my wits end with windshield wipers
ok, so i failed State inspection due to wiper arms not parking at bottom of windshield. have been reading and studying to try to self diagnose. here's where i am; replaced wiper motor, replaced wiper switch, traced, checked and confirmed all wiring is correct. still having same issue. wiper arms stop at top of windshield now when i turn switch off. used to be in the middle with old wiper motor. i have full function of low & hi speed. like i said, I've been doing a lot of reading and i figured the motor wasn't getting a good ground contact from the mounting bolt. i actually made a ground wire going from the firewall to the bottom left mounting bolt where the motor has the ground strap. no difference with ground wire on or off. i realize that the switch creates its ground from the dash panel itself. i have the switch in as tight as it's going to get making solid contact. I'm mechanically inclined and have assembled entire cars but i will be the first to admit that i have a weakness when it comes to electrical systems. my abilities end after installation. i can handle wiring and installing parts and fixing the mechanics of it all but when it comes to troubleshooting, diagnosing and breaking down basic electrical theory, I'm out. i'd hate to have to pay someone to figure out whats going on with my wipers. any suggestions?
