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?
