Not sure if my experience will be useful to the OP, but, when I had a bad cluster, here's the procedure I followed to resolve:
- One user's experience debugging a half-dead instrument cluster (1) which, after testing the fuses (1) battery & alternator (1) thankfully turned into an alternative battery search (1) and a simple battery replacement DIY (1)

I'm not sure about the LCM since I've never experienced a failure - but maybe the OP may benefit from one of these?
- How to repair (1) (2) or replace (1) your light control module & where to get new LCM chips (1) (2)
Please read the suggested threads and add value, either by pictures or by descriptions, so the next person stands on your shoulders.
