I have a 2005 Chevy Silverado 2500HD ext cab 4x4 long box. My brake lights work on the truck but they do not work on the right side of the trailer plug on the truck. I have checked the wiring and plug from the plug to the gas tank and I could not find a problem. Do you have a suggestion on where or what to look at next?

A Chevrolet Silverado that has cruise control problems might be having a problem with the part of the engine that controls speed and fuel intake. One culprit for this problem is the Speed Control Sensor that is located in the transmission. This part can be easily changed because it is more or less a probe that fits into the rear of the transmission.
Look for a loose or corroded battery cable. The problem may also be a faulty starter solenoid/relay switch - you might want to have it checked out.
