welcome to FABO!! about your ballast resistor you might need to replace it. they go bad quite often. if i were you i would replace it and keep another brand new one in the car somewhere, they like to pooch out at inconvenient times. I'm not sure about the cruise control, i'd probably just cuck it but it might be worth something?? hope that helps and again welcome!!
