Expert Reply:
My suspicion is that the problem exists on the Chevy somewhere, because the problem doesn't occur when towed with another vehicle. I'd first check the brake controller. Using a circuit tester, make sure you have 12 v going into the brake controller, and check for output when the manual override is activated. Also test at the trailer connector for current while the override is activated.
