| I've been having intermittent dropouts on my speedometer so I finally decided to pull and disassemble the cluster and have a look.... 
Looks pretty clean here... no obvious red flags ... 
Notice how the screws are also part of the circuit (this becomes important later).... Next I removed the speedometer module for a closer look...front looks fine... no obvious mechanical issues.... 
Circuit board looks fine ... what is going on? 
Ahh ... corrosion on the ground....gotcha? 
Cleaned up the ground up with a wire brush and the screw and nut with a small tap and die (Metric 3mm x 0.5) and then reassembled the cluster...fingers crossed... Plugged the cluster back in and put the rear on jack stands for a test run ... solved! 
I hope this helps someone else....
