Indicators, heaters, windows, rear door and wing mirrors aren't working. I've checked all modules, relays and fuses. I've had an electrician plug it in and the only thing not sending or receiving power was in the passenger rear door module. I've now changed the module and it works and locks door but hasn't fixed other problems.

Anyone have any ideas on what else it could be?

Have you had wet front carpets? 

This could be an issue with the CCM.

No, I've had the carpet up and no signs of water.

That's good. Definitely worth getting the CCM checked. Especially the contacts if they look corroded

The only corrosion I can find on the entire vehicle is above the bcm. Not sure what that wire or plug controls. 

Hmm I'm not sure. I think you might need an auto electrician to take a look
