I recently swapped the instrument cluster in my 04 trailblazer with an 05 trailblazer since mine had quit working. My trailblazer ran for 1 day and now it will not start. Did I do something to screw up the computer? Took battery cables off and pulled pcm fuses but nothing has worked. Any advice?

I have since reswapped the clusters hoping this would fix the problem but it has not.

 

Check all of your fuses before you do anything else.
