I have has the same problems recently.. My front & rear courtesy lights do not work when unlocking,locking or opening doors but still work from the switches. Lights on mirrors do not work either. Central locking from key fob will lock the car but not open. Batteries okay.. Electrician says CCM has no power going to it.. Carpets were damp so presuming this was water ingress so question is do I change CCM or check and redo wiring under front passenger seat ?.. Any thoughts
