Hey everyone, I have a 2004 CTS with two major problems. first, I cannot lower my windows or open the trunk using the driver side controls, all those buttons are disabled. It only works if I take the positive connector of the battery and place it back on after about a few minutes then when I am driving for about a day or two. I presets and the driver door controls are disable again. The front passenger control work but not the back ones. Next problem is when the car is in park or a still position if hesitates as if will shut of but it doesn't.

Any advice or ideas would be a big help.

 

... take it to the dealer ... don't mess with it.
