I'm posting with the hope that someone has dealt with the same issue on their 3rd gen. The problem is that my front wipers will work perfectly normal for weeks, maybe even months, and then will suddenly start parking at different heights. In other words, once the intermittent cycle is selected, the wipers will work fine, then every other sweep will cause them to park 2 or 3 inches above normal. This will go away for a while only to reappear and cause frustration on my part. When the truck was still under warranty, I took it to a nearby dealer and was able to replicate the problem with the service manager. He was confounded and did what any self-respecting service manager would do - asked me to make an appointment so the wiper motor could be swapped out. I did this, and found out that even with the new motor in place, the wipers were still acting as if drugged. When I noticed that the tech(s) had added a few nice gouges in my firewall, I opted to never return to the dealer. How hard is it to unbolt and replace a wiper motor without scratching the surrounding paint??

Anyway, the problem has been dormant for the better part of a year and just recently surfaced again. The wipers will do this regardless of which timed setting is selected. They do work perfectly normal in the steady slow and steady fast modes.

Does anyone know how many components control the operation of the front wipers - i.e.: motor, stalk switch, relay(s)? To me it seems as if electrical contacts , either in the switch, or in the motor, are dirty. If there is a general consensus that its either the switch or the motor, I'll tackle the replacement myself. Thanks in advance!
