I have a 2007 Silverado 5.3L LTZ. The cruise control has been acting up for a while, working sometimes and sometimes not working. It has been mentioned to me that the cause could be the brake switch. The truck was in the shop for transmission problems which for the 3rd time in 3 years they cant solve. But they did say it was throwing a code for the left brake switch. Does anyone know where this is, or if it could be causing the cruise control problem?

 

StrictlyChevy,

I am sorry to hear that you are experiencing this issue. When you say “shop” are you referring to an independent or a GM dealer?

Thank you,
Elizabeth, Chevrolet Customer Service
