the dashboard lights and surrounding lights have gone all dim like as if my battery is dying but battery seems fine with everything else working fine aswell just interior lights dim???? anyone have an idea why?

 

surely you can adjust the brightness
even shonky old fords can do that

 

has it got one of them electronic keys?

we've had it in the past several times where it's the actual ignition switch that stops communicating with the key

replacement switch needs reprogramming to the key and the vehicle electronics and costs loads so hope it's not that that's the problem
