2005 Other GMC Models 6 cyl Four Wheel Drive Automatic
i was off roading in my 2005 gmc canyon when I slid into deep running water that came up iin my truck over the speaker on the passenger side. The driver side was above the water. The truck sat in the water for about an hour before we could finally get it out. I left it running but the horn started to blare for no reason I turned the truck off and it won't start back up. The windshield wipers come on uncontrollably as well as the headlights, blinkers radio, and various other things. While it was running it also would not come out of 4-lo. I let it dry out over night and the same things are still happening. Any ideas or suggestions?
