Speed ometer and tack omiter dont work all outher gadges work

Check tat the speedometer and the tacometer wire are properly connected at correct position.if it is cut change the wire

If was only techomeer would have suggested Alternator. as an option get that checked, can usually get it done free especially if you are a member of a motoring organisation.

Speedo is usually operated via a connection to your wheels so that connection may be damaged if you have 'bottomed out; your car anywhere.
