Brake Light On problems of the 2006 Chevrolet Trailblazer

The summer of 2013 I had it brought to my attention that my driver side brake light would fail to light up as the brake was applied. I tried changing the bulb but that proved to not be the problem as it still failed to light up. The following summer the same thing happened with the passenger side brake light. I am unsure if it is an electrical problem or a sensor that has gone bad. I can only assume that it is an electrical problem due to the fact that the back windsheild wiper stopped working due to electrical issues.

Rear brake lights keep going and having to change them bi weekly.

I was driving home from work in my 2006 Trailblazer ext. After stopping at the stop sign in front of my home, I pressed the center button on the overhead console to open the garage door and proceeded to turn right as to position the vehicle to allow for backing-up onto my driveway and into the right parking half of my garage. But as I shifted the Trailblazer into reverse, I began to press the accelerator pedal, but the vehicle would not move. I could feel that the transmission was not slipping, the engine was under load, and it was as if I was pressing the brake at the same time I was pressing the accelerator pedal. But, I only use my right foot, and my left foot was in front of, and against, the drivers seat, far away from both pedals. I looked over to the parking brake, but it was completely down. Using the parking brake lever, I made certain that is was not engaged. The brake light in the instrument panel was not on at any time, nor was there a warning from the driver information center (dic), nor was there any other warning or indicator showing that something was wrong. I still could not get the car to move. I placed the transmission into drive, and I could feel the transmission shift, but again, I could not get the vehicle to move. And, there was a load on the engine as if I was pressing the brake pedal at the same time as I was pressing the accelerator pedal, but the brake was not being pressed, and my left foot was far away from the pedals. Finally, after about a minute, I felt that the car was ’let go’, and I was finally able to move the car normally onto my driveway and into my garage, but I was shaking a bit and am very concerned that this is going to happen again.

2006 Chevrolet Trailblazer. 5. 3 liter v8 engine. Tapped brakes lightly and took foot off brake pedal. Brakes continued to activate on their own and continued braking harder and harder until vehicle came to a stop on it's own with the brakes locked up. Had to shut off vehicle and restart to release brakes. Called ryan Chevrolet in buffalo, mn and miller Chevrolet in rogers, mn. They said they have not heard of any problems with the brakes doing this. Could have been bad if on the highway or freeway since the brakes would have completely locked up. Only happened once. . . And that's enough!.
