Started my car this morning and noticed speedo revs temp fuel and the kilometres wasn't showing up or working the needles don't move.... When i try too use the mode thing nothing happens. I have pulled the dash out too check connections and all is pushed in well and i have check the fuses under the steering wheel..

What may be my problem?

I completely forgot about the ones under the bonnet, i'll test them tomorrow and resetting it means the whole computer thing? Like key in the ignition for 120 minutes?

And with the BCM how do i test that?

Could be alternator over charging.

Is the battery light coming on?

If so you may need a new voltage regualtor

I've had a look around in and around the fuses and relays under the steering wheel and i had a look at the BCM relay and tested it with a multimeter now.... I got readings saying

I took the plastic cover off so i could click the copper pieces together too complete the circuit

Constant volts *Not completed* (Or whatever) 0.11
Completed circuit 0.08..

Could this be my BCM relay has worn out?
