03 trailblazer brakelight problem

all of a sudden my brake lights do not work. My 3rd brakelight works but that is it. I checked the fuse for the brakes and it is ok. I replaced bulbs still doesn't work. Is this a common problem with this vehicle or can some one please help me.....:confused:

Lots of problems with the tailamp modules, check with your dealer if the recall applies to your truck.

03 t/b's had a recall on the taillight modulkes.. had mine replaced a few yrs. ago. Even after replacing,the brake lamps blew out prematurely, so I just had them replace the modules again. It is a safety issue,so they will oblige.
