    Cruise won't work, any suggstions?

    Guys,
    Need some help diagnosing my cruise control, as I would like to do some major trips this year (Barber, O-Fest...).

    Checked the column switch, brake pedal switch, clutch pedal switch, swapped in another actuator, and two other computers, but no luck, won't activate at all.

    Any input? TIA!

    Clean all the connections in the tail lights. If they are corroded it wont work. The CC grounds out thru the brake lights.

        yeah, i just don't use mine anymore after 2 scares where it got stuck on acceleration. it was scary as hell and definitely made me have to change my brake pads way to early. one of the times there were still plenty of cars on the road but all movin, i had to pull over, turn it off, turned it on and it just went to redline, played around and finally it turned off, weird and not safe. -dan
