Default has anyone split the case on a BCM

I want to see whats going on inside a BCM on my C6
I wondered if anyone has ever managed to split one open, I have prised the clips open and removed all of the fuses and relays but despite some pressure on several screw drivers I cannot get it to split, I can just see the electronics inside but I want to thoroughly clean all the contacts and components
Any ideas would be awesome, thank you

I have to ask .... why would you want to open a a perfectly good sealed unit if it is working fine ?

There are BCM'S that operate for years and years and have never been cleaned

I didnt say it was a perfectly working unit, the reason I want to open it up is that it is NOT working

I am an electronics specialist and want to trace the damage to it and 2 others I have

I have new replacements on order and use a Tech II to program them and I usually mess with C5s but I have several C6s right now that need attention

Corrosion, which will cause a short, done it so many times before with sucess as long as the car has not been powered up

Despite having new BCMs ordered that I can program I still want to have a go at repairing these, its my personal challenge

Share pictures if you don't mind. Just curious what it looks like. My bet is a board with stuff on it and plugs.

Thank you for responding, no I am working on the BCM modules in the passenger footwell and then after that the Bose power amp modules

I will have time this weekend to hopefully mess with one of them, I have replacements on the way just my Tech II tool the Candi interface has quit on me so waiting on a replacement.

My biggest enemy is lack of time

I have managed to get 3 out of many C5 BCM modules to work just fine, this is the first time messing with C6s

I am not guaranteeing
I can get them operational but sure am going to try
