'94 F150 with tilt steering wheel. There is a glitch in the steering column. It started out with the wipers not working properly and is now progressed into ABS light coming on and not going out, right turn signal not going out even with key off and wipers not working at all. What kind of a bag of worms will be opened if I jump in there myself? Is this a common situation possibly related to the tilt wheel? Any and all comments would be appreciated.
