Brake lights work but tail lights do not....need some help

otacon88

There wasn't an electrical section so I'm just posting here so I can get some help. I have a 2012 base that I bought in May, just last week got a lot of body work done (front lip, vented fenders, side skirts, and rear bumper). I was told the rear tail lights had to come off to remove the bumper. Ever since getting the car back, the tail lights do not work when the head lights are on, but the brake lights work fine if I push the brake.

It can't be a blown/dying bulb, the car is almost new. The mechanic said he didn't mess with any wires at all, just unplugged the connection to the tail lights then re plugged it back in. Doesn't look like any wires are cut either.

What could the problem be?
