[Vwdiesel] 97 Speedometer

[Rudy]

I'm working on a 97 Jetta, it's gas but I imagine the Speedometer Cluster is
the same as Diesel.
 
I don't know anything about these Cars with the Electric Speedometers but
I'm trying to figure it out, neither the Tach or the Speedometer work.  It
was in a minor Front End accident and the owner can't remember if it worked
before (Daughter's Car)
 
Any one have any ideas where to start diagnosing this problem?  Suggestion
will be appreciated.  Thanks in advance for any help.
