It started totally by accident when I was driving across a field dodging holes and such. At first I didn't think much of it on the way in but once my work was done I did the same on the way out and the same thing happened. All recalls and applicable TSBs have been performed on this truck. Since the steering is electrical I think it has something to do with that, but I have no idea why its related to the blower motor.I have never needed to turn my steering wheel back and forth 5-8 times, so...no. Were you doing this?
