Dashboard background lighting for speedo and revcounter etc

You have low voltage in the battery,all the best.

I have a similar problems on my 2005 9-3. It has developed a number of minor electical issues. including dial and false warning light triggers. I have fixed most of them by simply going round the car disconnecting the electical connectors and spraying "switch cleaner" (Maplin or Radio Shack).
The only problem I have left is the rev counter occasionally starts reading high, removing the fuse (end of dash panel - 4th fuse down) for about 30s with engine off normally resets everything back to normal.
Hope that helps.

with the motor running?your problem is vague but whatever it is be sure to check the fuses and if they check out ok get a good auto-electrician to take a look at your vehicle

It may be overdue for a scheduled tune-up, oil change, etc.

My 04 Ford Focus the battery light keeps coming on & going off, have fitted a new alternator belt but it didn't solve the problem. The battery connections are good. Also the rev counter, speedo & mileage clock keep going haywire when the battery light is on. Do you think it is the alternator? Or is it some other common problem?

speedo drive sensor on transmission failing or loose or dirty connections

could be needing replace best to check with the main dealer

the dash control board is the controler for the boards in the dash, fuel temp etc. inside the dash itself, a board on the rev counter controls voltage to feed the the fuel gauge etc. the back of the speedo burnt,there is the 3 pin voltage control chip on the board. you can replace the boards. you can remove them from another dash and place them into yours but if you say the board burnt out on the speedo . then i would just change the dash as it would be easier as you would need to replace the speedo as well. you will also need to inform dvla that the speedo has been changed as for mots its recorded. or have the speedo rectified to the right mileage. not informing dvla can affect your insurance.

HAVE YOU TRIED DISCONNECTING THE BATTERY & RECONNECTING THE BATTERY THIS SHOULD RESET REV COUNTER.
