So..... brake light housing mint, no corrosion, towing socket dry, just realised the top brake light comes on dim when the heated rear window is on, then goes bright when peddle pressed, also no rear wiper or rear door central locking ? Instagram; @gavin_walding

just realised the top brake light comes on dim when the heated rear window is on, then goes bright when peddle pressed, also no rear wiper or rear door central locking

power back feeding if the top brake light comes on dim when the heated rear window is on (water shoring out elect connectors ) as they are two CCT power form two places

Connector Plug C0704 is the common point for both cct check it for short out
