Multiple factory accessories don't work...coincidence???

[Chevynut08]

I have an 05 yukon SLT with Autoride. It's almost time for inspection so I'm tryin to get this done myself. When I bought the truck the fog light lenses were missing and so are the bulbs. Also the rear windshield wiper doesn't work nor does the tow/haul button. I believe I've checked all the fuses and are all okay but I haven't messed with relays. Could all those things be linked somehow or do I have some serious work ahead of me?

The tow/haul button not working could be due to a broken wire in your steering column. If you do a search here there are several good threads describing how to open up your steering column cover and see if that is the culprit. If it is, its a pretty simple wire splicing fix.

As for the rear wiper, I'd open the back panel and test for voltage at the motor. If you're getting voltage when the rear wiper switch is turned on, you likely have a bad wiper motor.
