Hi ( amongst all this chaos - hope everyone is coping) my 1991Eunos is getting a service just now - the dash light and sidelights have not been working - ok during Summer but annoying - I had a fog light fitted for MOT last year - it seemed to follow that - any ideas ?
Stay safe
The same thing happened to me when I fitted a fog light switch. Take the switch off the dashboard, it easily prises off, and make sure the connections are pushed on firmly.
Dash lights not working usually means someone worked on the 3 switch positions to the right of the steering wheel (say, fitting a fog light switch) and unwittingly unplugged the dash lights dimmer connector. Even if the car doesn’t have a dimmer fitted (most don’t) it still has the wiring, and the loom is plugged into the back of a blank switch which has a wire link jumper in it to complete the circuit. If you unplug it, the dash lights go out.
Not so clear about your saying the sidelights don’t work; if that had happened while your foglight was being fitted, you wouldn’t have passed that MOT.
Sorted ! Ta
