I have a 2007 chevy Silverado 4 door short bed. My cruise control will only work like every 3 months if at all. The cruise control light will come on on the dash but cruise control wot set. Also when I first bought it the passenger door window control wouldn't work so the dealership replaced the switch which it worked for a year and a half then stop working again and not only did that stop working on that door the power locks switch stopped to. Given if you play with the window switch for awhile it will work. The driver side control for the passenger window wont work either. Is there something I can do that wont cost me a arm and leg to fix these issues?
