Hi all ive a problem my tail lights are mad iny 2000 cl500. 1st up i got an error msg on the dash saying rh tail light out substitute bulb in use... checked all lights working pulled globe holders out one had a tiny amuont of corrosion cleaned up sprayed all contacts with inox no change globes all checked out ok.. decided to check lh side at the same time bad move... pulled all globes and checke all ok. Started car got three error msgs now lh tail light not working lh rear fog light not working also lh reversing light not working and checked they are not working now.... checked contacts with led tester no power at all lights contacts that are showing error msg. The only thing i might have done wrong was pulling globe holders out while lights were switched on... any ideas anybody im stumped whats goig on checked fuses under rear seat all good. Cheers brett.
