do the brake lights come on when the lights are off? try checking the fuses in the vehicle for parking lamps/ running lights. the fuse cover should tell you what each fuse does

Behind the right (passenger's side) taillight assembly is the bulkhead connector for the rear lights. Remove that taillight assembly and inspect the wiring. If the exhaust problem was hot enough to melt or distort the taillight assembly chances are that wiring harness is damaged as well and that's why your lights are out. That wiring harness feeds both taillight assemblies and the license plate lights too. Those taillight assemblies are also notorious for separating and allowing water to get in the assemblies. Over time this water damages the bulb sockets. Rust and corrosion forms and you wind up with bad bulb connections. So inspect the sockets as well. Remove the bulbs and clean up the sockets. I had to replace both taillight assemblies on my '00 Grand Prix because of that issue. I got about 1 cup of water out of each of the old assemblies. 1997 thru 2003 models are the same taillight design. HTH. -Jim

Well, found out that the wires had melted, the wires needed to be pulled apart from each other and wrapped with electrical tape.. the wires touching caused the fuses to blow repeatedly so once I pulled apart and taped the wires on the tail lights.. the fuses didn't pop and the tail lights became fully functional. Thanks for the input from everyone.
