Tach, spedo, boost guages are not working correctly

[th3175]

The  Speedometer Doesn't have right speed. The HUD doesnt work all lit up. The tachometer doesnt show right RPMs. And boost guage doesnt work. But Fuel gauge works oil pressure works and Radiator temp work. Need help to fix please.

Are you on the W-Body forum?  Robert Saar repairs them for $35.  Your HUD problem may not be related.

i'm here too, just much less often.
HUD..... i don't know, i've been seeing a lot of them die off lately.

For what it costs, just send it to Saar.
