hello . do you also have a tilt column ?

Expert:  Kevin Bourcier replied 6 months ago.

also . do you ever see any fluctuations on your speedometer or lose the speedometer ?

Expert:  Kevin Bourcier replied 6 months ago.

One thing you could try is when the cruise will not set , put your foot under the brake pedal and pull up on the brake pedal and try again to engage the cruise control

Ok. I also noticed that my brake lights do not work. Tried changing out the bulbs. Nothing. Changed the brake switch and no change to either problem.
