I bought a 95 SC300 earlier today and the RPM/MPH needles won't move! Help?

 

Smack the top of the dash. Literally. Hit the part that's right over the instrument cluster. It's not recommended (OLT will know why), but it works. That's what I do when my RPM needle is feeling bipolar and refuses to work.

 

Take it back apart and slightly, and I mean ever so slightly, pull up on the needles, to see if it frees them up any. Before you put it back together, take for spin to see if the mph works.
