Default 1989 xjs cruise control
My cruise control quit working and while trouble shooting I found it had no power to the switch on the brake pedal. Power to the brake light side but not to the cc side. what do I check now. Thanks.

Are you talking about the switch with the Green and Green/Purple wires to it, or the switch with the Yellow/White wires to it?

I would check both fuses for the cruise control. If they are fine, I would suspect a bad cruise control ECU.
