Hazard lights flashed all winter. Had to disconnect battery every night
Immobilizer light now on constant but dim. Roof will not open. Car starts and runs without a problem. No warning on dash or any sound from roof motor. I've checked the fuses and have electric at the switch and motor but roof is dead. Does anyone think this is all connected? I would be grateful for any advice. Thanks in advance, Peter.

Yes it does sounds like the BCM is not working correctly which can cause these problem. To confirm lets run a CAN scan to see what comes up. here is a video to show you how:
