Whats the easiest way to test if my wiper switch is bad?
Just don't want to get one rebuilt if it's not actually the switch.
If all the settings work, and the wipers park when you go to OFF, it's OK. If one or more of the settings don't work correctly (i.e., slow/fast speed, intermittent, etc.) or the wipers won't park correctly, it's faulty. In which case you may want to buy a refurbed unit from Icemark and send him the faulty one in exchange. Or you can attempt to fix the switch yourself using the instructions on his web site.
