Have you found the problem yet?
Saw a problem similar to this on a Dodge truck. The wiring ran on the bottom side of the column inside the plastic cover. There was a electrical connector about 6" below the wheel which made it nice to work on if you had to pull the column apart. The harness had been put in without enought slack. The tilt-wheel had been moved all the way to the top and the connector simply unplugged itself.
