The cruise control on my 2000 Blazer LS 4X4 is not working. I just changed the multi-function switch and still nothing. I looked at the throttle cables and they seem to be fine. All the fuses are good as well. Any help is appreciated.

Check and see if any of the brake lights are out. If there’s a burned out bulb for a brake light the cruise won’t work.

Brake lights are working. I tried replacing the controller under the hood as well. No luck. Any other ideas??

The next thing to check is the brake pedal switch. When the brake pedal is applied it shuts the cruise off.
