Hi there. I just got my 2009 Suburban ltz, around 72k miles. Every thiing seems to be owrking fine except the cruise control. I can start it, the light goes on the steering wheel, however it does not engage when I try to set.
i have tried different speeds, moved the pedals backward and forward. And checked that brake lights are working when the pedal is pressed.
checked teh fuses under the hood, but couold not find none to do with cruise control.I have read so many posts about cruise control, most relate this to a faulty brake switch on the brake pedal.
my questions :
1- how can I check if the brake pedal switch is faulty or not giving that brake lights are working OK?
2- what fuses and where to check?
3- is there any mechanical parts that can be checked(if the previous owner have removed for some reason)?
