hi my corsa has got a digital dash in it when you first turn the ignition on all the gauges go up like they are meant to but once you start the engine there is no reading at all on the temp gauge part any ideas

Has it always been like this?

Check the connection on the temp sensor. It may need cleaning, or it may not even be connected properly.

I have no idea. I would guess it will be on or around your thermostat, which is likely to be at the front of the engine closest the the radiator.

Another option is to trace the loom through the engine bay and check it is fully earthed. A dodgy earth wire can cause all sorts of random havoc.

sensor

Hi

I had this problem in my old car and i checked the temp sensor near the front bumper and it was just a dodgy connection. maybe just checking that could sort it?

the dash worked properly before i checked the radiator wire none off my fuses have blew ive had the digital dash out and the bulbs on the back of it are ok too plus since it happened ive got no indicators and the break lights are not coming on just checked some of the fuses and they dont have a ignition live going to them while the other fuses do hopefully something to do with this
