Recently I went over a drain and my dashboard lights (backlighting) went out and also the backlighting for the clocks making it hard to see the dash in the dark.

It sometimes comes on and then goes off (only twice this has happened) has anyone had the same fault or can anyone send me any wiring diagrams thank you (car is a mk1 Octavia vrs is modded) 

Did go over the drain to see if lights would come back on but no luck, checked fuses also.

It's quite easy to remove the instrument cluster from the dash. 

You could try pulling it and checking the connectors at the back are in properly, look at bulbs etc. 

I am of course guessing but maybe worth a look. 

 

I had mine out the other day but didn't unplug it- I am considering buying a used replacement  (my clock display is defunct) but I wanted to just see if it was difficult or not first.  

 

 

 

 

The backlighting is all done with surface mounted LED's so not easily replaced, as it failed after going over a bump, check the bottom row of the relays behind the drivers side lower dash as there is the amplifier for dash illumination

Or its likely a dry solder joint (was a load of posts about it a few years ago with them failing) cracked when it got knocked.

 

Have a search as there is a guide somewhere on how to "reflow" the cluster circuit board which is a probable cause.
