All of a sudden today, my blinker/headlight control lever and my windshield wiper levers both stopped working simultaneously. I've never had any indication of a problem before this, so it seems very surprising. I've removed all the dash area panels to expose the wiring coming from and in the area of the steering wheel. I figured something must have rattled loose, a snap in connector or something, but all the connections are snug. Anybody have any ideas? I'd really appreciate any info. I don't want to take it to the dealership and end up paying $500 for them to fix a short.
