Question about 2004 Chevrolet TrailBlazer
Make sure they didn't replace your stock bulb with an LED. They draw less amps and trick your flashing unit. Try a digital flasher (U-Haul sells them) if that doesn't fix the issue.

SOURCE: electrical problem
Find the ground wire on one of the lights and add another ground wire to a good clean metal surface and see if that fixes the problem. It defently sounds like a ground problem at one of the lights.

the most common problem is the light boeard in the tail lights usually replace the board full of bulb sockets and that takes care of it but before condeming the board make sure you are getting power to it

If new bulbs don't work, it is probably the harness that holds the bulb. I had to replace both on my car after fighting with the problem for over a year and not knowing.

you said lights are working fine on rear but generally when they flash fast there is a turn signal light out on the side they flash on. Did you look at the turn signal light on the front of the vehicle?
