Welcome to Just Answer
It sounds as though you have a BCM problem.
The BCM (body Control Module) controls items such as lighting, wash/wipe, heater, alarm, immobiliser etc, and is like a central computer.
Usually when the malfunction, it is a sign that they need to be replaced, however sometimes they can be reprogrammed, in either case it will need to go to a specialist, as a replacement will need to be reprogrammed using specialist software.
Most good auto electrical specialists should be able to help, and will have the required software.
Hope this helps, if you need more info, please let me know.
