cruse control shutting off at 65mph and over. I have installed new brake switch and still have problem.

33,000 miles 97X ARC 5.3 Car was left for 9 months and not started. When I returned from long stay away I found a dead and a not reusable battery (1 year old). Put a new battery in and the car started fine but when I shut it off the blower motor stayed on.

rear suspension goes down after sitting for a few hours and goes up after I start the vehicle

car is dragging and making noises when I turn

On very slippery and snowy roads tonight, the AWD is not engaging. Only the rear wheels are spinning, making the truck very bad in the snow. There are no codes in the PCM and no MIL lights.
