Hi there, i found this thread about dash lights dimmer not working and saying something about a dimmer relay and also something to do with tail light fuse!?. I have the same problem but... my ignition ring bulb and also the dome light doesn't do anything when set to "door", But if set to "on" it works fine the car was upgraded with LEDs in dash and center dash before i bought it, but have been told this would not effect it.
I would like to know if this dimmer relay is real and also if the tail fuse has anything to do with this aswell. Any help would be a big help as it has been in my head ever since buying the car. thank you in advance
