Intermittent speedo. failure

[smross]

I drove off in my '84 Sprint yesterday morning and the speedometer did not work and neither did the odometer.  The trip odometer did function.  After about 20 minutes the speedometer and odometer miraculously came to life and continued to function perfectly the rest of the 2 hour drive. 

I assume that something must be on its way out and I'd like to know what to look for, especially since the problem appears to be intermittent.

I have a Smiths mechanical speedometer.  I checked the archives and could not find anything that specifically related to my problem.

Thanks in advance.

Best,

SM Ross

From what you describe the fault is in the speedometer unit.

There are two recommended repairers.
