Re: Cruise control problem
Is your brake warning light on the dash on?
Have you checked the vacuum switch? If not, unplug it and try that.
Have you checked the parking brake switch?
Is your third brake light working? If you changed to LED, you need to add a resistor.
And last, pull the steering wheel and check the 3 spring contacts.
I have been through all of this. Mine had a bad vacuum switch AND one of the contacts behind the wheel was loose. It would loose contact when I turned the steering wheel.
