My friend has a 93 Ford Escort...1.9 lit engine i believe...He has had ignition switch problems in the past...changed 3 times....Yesterday..all of the sudden his wipers and heaters stopped working (blower)..while driving. We check fuses --all good..no sign of loose wires...could this be somehow affected to the ignition switch???....maybe faulty wiring in replaced ignition switch?...any advice is appreciated.Thanks!
