flytopher Posted April 21, 2019 Share Posted April 21, 2019 2011 TC XLT with 160K miles. One day last month, the front wipers came on by themselves, and I could not shut them off. I finally had to pull out the under-dash fuse to get them to stop. Symptoms: Front wipers always on, rear wipers don't work at all, washers (front and rear) don't work at all. I installed a new wiper switch (on the steering column) and that had no effect. So, now I don't want to throw any more parts at it until I have a firmer idea about what is wrong. Oh, another problem...the 'door ajar' light is always on, and that makes it impossible to lock the van. That happened a few months before the wiper problem. I don't know if it's related. Any ideas, people? Quote Link to comment Share on other sites More sharing options...
ncranchero Posted May 18, 2019 Share Posted May 18, 2019 Sounds like it could be a GEM issue. Have you disconnected the battery (both terminals) and bled off any residual voltage? Quote Link to comment Share on other sites More sharing options...
flytopher Posted June 18, 2019 Author Share Posted June 18, 2019 Turns out it was a wiring harness that deteriorated in the back(!) door. The signal goes from the steering column through the rear door and back to the front. I never would have figured that out. Quote Link to comment Share on other sites More sharing options...
