I had a battery light to begin with,new alternator and battery installed, now I have no power steering and a light on for that, battery light still on, traction control light on, and the parking brake light will not go off. I pulled the kick panel and sprayed the connectors with electronic cleaner, no change , also took wiring apart at the engine spot with the cable wire tie that is a usual suspect, and no corrosion found. I am at a loss what to do next.
