Ok, we got a ton of snow overnight last night. I let the van warm-up and wiped the loose snow from the windshield then turned on the wipers. After getting on the road all of the sudden I heard a loud pop/snap and the windshield wipers returned to their down position and stopped working. I can still hear the motor running and a popping noise. I am thinking the linkage broke or came undone. I can't seem to find a diagram or step-by-step on how to fix this. I also don't see the the wiper motor on the fire wall. I need to fix this asap, so help me out here boys..
