2001 Chevy Express 2500 No tail lights, good fuse, bulbs, no power coming to them.

 

Brake pedal switch?

 

If there are no turn signals, it could be the T/S column switch. The brake runs through it.

 

Bad switch or damaged wire running to tail light.

 

Had an issue with the tail lights on a 2001 GMC Savana van. Turned out it was the wiring harnesses in both sides. An issue that would occur when the headlights were on. I picked them up on Ebay for about $30.00 each. Once replaced, they were fine.
