1989 Speedometer not working?
 

1989 911 - Speedometer not working at all

I took my car out last Sunday and the speedometer is not working at all. It worked fine the last time I drove it a few weeks ago. When I turn the key on, the needle just barely moves a hair and then stays at 0 MPH.

Any ideas? Is the sensor somewhere on the trans? Aside from a loose connection, is there anything I should check? How do I diagnose the sensor, or should I just buy an new one and try it out?

Thanks!

If the car was park for a long period, voltage drop could cause the speedometer acting up strange, I have the same problem and wasted the money on speedo sender until I found out the voltage issue, try to drive your car for at least 30 miles for full charge and see if the problem may fix by itself

Good luck

could be linked to the trip meter-my speedo stoped working when i reset the trip meter a few months ago-try gently resetting it,it worked for me.

Thanks for the tips guys. I will try them out and report back.
