2003 Pontiac Aztek

Electrical problem
2003 Pontiac Aztek 6 cyl Front Wheel Drive Automatic 98,000 miles

My 03 Pontiac Aztek has multiple problems, for starters the speedometer, tach, fuel gauge, and the lighted digital odometer went out and none of that works anymore, just today I parked the car, put it into park and the key would turn back enough to shut off the engine but not the accessories after a few minutes of moving the steering wheel up and down turning the car on and off and shifting it in and out of park the key finally turned all the way off. What would be causing these problems?

For the cluster problems, have the body control module tested. The key is another issue. Have you tried lubericating the tumbler?
