Does anyone know how to open the PCM medal box to get to the printed circuit?

I took all the screws out, so there must be a trick to it.

 

Why are you attempting this?

 

No response from PCM for the 4x4 system. 4x4 module is a part of the 2004 PCM. I can fix small issues with the board, copper trace or reflow the solder. Since it is already damaged I have no issues with trying to repair since I think it is just a damaged copper trace, rather than an estimated $1100 replacement at dealer.

 

You can buy a reman PCM for less than $300. Then all you have to do is pay the dealer to flash it.
