Title: Speedo & Tacho dont work
Post by: David the Plumber on 26 May 2010, 16:00:06: Got a 2.0 GLS Estate 98 (S reg)
suddenly the speedo & Tacho dont work. Also the dashboard light on the left side has stopped working. Funnily enough the milometer is still working.
Its not mentioned in Haynes, or the vauxhall maintenance program I have.
Any ideas??

More likely to be dodgy connections to the dash. I doubt disconnecting the battery will achieve owt. ;)

Like most technical problems....turn it off, turn it back on again. We dont understand why it solves things, it just does :y

The dash makes it's connections when it's pushed into place, it could very well be these connections. Take the dash out & check the connector block .... you'll see when you remove it. :y

How easy is it to take the dash in and out?
Im guessing if its just the rev counter/speedo not working then the abs/tc ecu should be ok? Then again I have got a brake light check come up on the dash info screen, but all the brake lights are fine?

cheers
