the wipers in my '83 Jimmy are not working. There is a brand new motor in it which will work when I use a jumper wire. I'm almost thinking the wiper switch is to blame, but not sure. Reason being, the dash lights seem to act weird--- the right turn signal indicator goes on when the left turn signal is used and vise/versa. Also the climate control panel light flashes with the turn signals as well. If I bypass the wiper switch, the dash lights all work fine. I have tried 2 used switches but to no avail. Haven't tried a new switch yet. I have also pulled out the wiper delay box inside the dash, and tried some used non-delay switches hooked up to the harness, which didn't help. Anyone have any ideas? This is the in-dash type switch this model year.
