Ok, my cruise did not work the other day on the freeway. The light comes on, but would not set (hold) speed. Then the next day I tried it again, and it worked this time. Then the next day, I am using cruise and it starts accelerating out of no where. I let it go to try to see what it was doing, but as it started rounding 90mph I turned it off. Then today (day 4) I notice my blinkers are not working. They don't do ANYTHING... no blinking on the dash, no blinking on the truck. The cruise still doesn't work either. My head lights work. My tail lights work, and my horn works. Anyone have any ideas? What should I start checking first? THANKS!!!
