My windshield wipers started working intermittently, working, not working, and only working on the high setting. this would happen while i was driving in the rain, almost forcing me to pull over. finally, my wipers stopped working all together on all speeds accept for the highest speed. at the same time, my ac/heater fan stopped working on all speeds accept for the highest speed. i searched online to find out what the problem was, and i came across a lot of complaints on the same issue. it seems that these trucks have a defective brain that causes this potentially dangerous problem. i was quite surprised to find that this systemic problem has not already been recalled. that is why i decided to file this complaint. thank you *tr
