I'm not sure when exactly they stopped working... I just noticed that neither of them were turning anymore. My speedo and tach both work fine, but I'm concerned because I'm trying to sell my car and I doubt anybody will be even remotely interested in it when they can't know for sure what the tru mileage is... Has anyone else had this problem? Does anybody have an idea as to what caused this... Or how to fix it? Any advice would be greatly appreciated. Oh yeah! btw... It's an '85 CRX Si... Thanks in advance!

 

my mileage doesnt work and my speed dont work either... Idk whats up with it

Make sure the cable is plugged into the block.

 

speedo pluged into the vss in the tranny ?

 

If the speedo still works but the odometer doesn't, you probably have a broken drive gear inside the gauge. I've had this happen twice and both times tried replacing the gear, but both times ended up breaking the gauge and putting in a new/old one.
