I have noticed an annoying issue on my '94 (4th gen) Honda prelude. The digital petrol and temperature gauges appear very faint when starting the car. After about 5 mins they brighten again, only to fade once more a few moments later. This repeats throughout driving.
I've checked the instrument light dimming switch, and its fine (on full).
Would anyone know what could be causing this?
We've had a bit of rain here lately, could that be affecting it?
