I just bought a 1999 XJ Sport, 4.0L with 92,000 miles, It's never been off-road, and in great shape. The cruise is not working. It will not set, the light in the dash does not come on and the lights in the wheel are not lite at night. The airbag check light cycles as it should and the horn works, so I don't thick it is the clock spring. I have cleaned the connection at the Vaccum unit, it looked good. Any ideas? Do the switches light up when the headlight are on even if the CC is not on?
