Question
My 2006 Trailblazer all of a sudden had an electrical problem.  

-Power lock isn't functioning at all
-Power windows are not functioning
-Dome lights on the inside of the car are not functioning
-Lights to see the MPH and all those gadgets aren't functioning.
-Radio isn't working
-Rear lights are not working also.

These are all the problems that occurred all the same time I noticed anything wrong with the car.  I'm looking for any suggestions on what the problem could be so I can move forward towards getting this problem solved.  

Also, I've checked all the fuses both under the hood and under the back passenger seat on the driver side.  When I used the fuse checker, the green light turned on when I tested all the fuses.  Any advice is appreciated. Thanks

Answer
It seems these problems are common on this model.The cause could be the tail gate module or the body module.Other cause could be the ignition switch but as your car is 06,unlikely.Easiest way to fix this is have the dealer or someone with a tec2 scanner diagnose this problem.The module is behind the drivers seat im not sure where the tail gate module would be.Possibly in the rear.
