I had a problem with my car that required it being at a repair shop for close to two weeks. Though the problem was engine related and not electrical i noticed after i picked up the car that the rear window defroster was not working. I also noticed that my wipers will work at second and third controls but will not work on the first one. I went back to the shop and complained since this problems were not present when i dropped the car off with them and they told me they did not work on anything related to wipers or rear defroster. They now want me to bring it back for repair for extra fees. I will love to just fix it myself but i need all the help i can get!
I'd say check for blown fuses, but then again, the wiper problem sounds related to the switch, I doubt the speed controls are fused seperately from each other...
Also, the defroster wires are kinda brittle, check the fuse, and ohm out the wires where they come off the glass.
Good Luck!
