I'm just trying to make sure you got everything covered so don't think im trying to put you down. Did you push and turn on the main power for the cruise. I had the owner of my old p5 call me after a week cuz he didn't hit the main switch.
Good catch, forgot about that one......After checking the main button, make sure all your brake lights are working. My old car wouldn't turn on the cruise if one of the brake lights were burned out, as it saw the problem in the brake electrical circuit which is uses to turn itself off when you hit the brakes.
Zombie thread!
I just put in LED brake lights, and now my cruise doesn't work. Will putting in resistors (like you would to relieve hyper-flash in LED turn signals) help this? The cruise literally worked the day before I changed to LEDs and that night it wasn't working for me.
