I replaced the front bumper From aftermarket to stock. Had aftermarket fog lights hooked up and I accidentally crossed the wires when dissembling. Ok no big deal. This truck btw had fog lights originally. Whoever owned it before me just stuck bare wires into the stock fog light connection. Anyways, it Popped the 30 fuse under the hood when the wires crossed. Replaced that and now they still don't work. So went out and bought a new relay and replaced that. And they still don't work. Can hear the relay click when i hit the fog light switch on the dash. Tested for power at the fuse under the hood and have it. But there's still no power at the plug for the lights. I cut back the wire a little to test for power behind the plug and there's nothing there either. Also checked power at the switch and have power there. No faults or anything showing up on the dash. What am I missing?

The specs say that it will run in EV mode up to 30 mph and get 20 mpg in the city. It turns on the engine at very low mph and gets 16 mpg city with very careful driving. Chevy service reps in Dublin and San Leandro Ca say that this is normal and that nothing is wrong.

Car has 40,000 miles on it and has both dealer and manufacturer warranties, but the service advisors will not look at the problem unless I agree to pay them if they can not find the problem. They do not consider the early engine start and the low gas mileage to be a problem.
