i have a 1997 p38 diesel auto dhse , I have just changed the BECM , engine ecu, dashboard, door lock and ignition key etc, engine now now starts air suspension works , but I have consul lights or radio some switches work but windows don’t as the hevac unit , the revise lights stay on when in P slip into neutral go out any help please
 
I've seen issues like this on my tester (which is set up for testing auto vehicles) when I've put a BECM on from a manual vehicle.

My guess is that the BECM you've fitted is set to Manual transmission.

What was the reason it was swapped in the first place?
