I have a 2007 SilveradoLT
Z, 4WD, 5.3L. Over the past few months my cruise control has worked and not worked for no apparent reason. Some days I would get in it to go to work and the cruise would work normally and if I had to hit the brakes for any reason it may or may not come back on at all. Now we're to the point where it doesn't work at all anymore. The on/off switch still lights up and I have checked all the fuses. Checked brake pedal and switch. I have no idea where else to begin.
Any help would be greatly appreciated.
