Used to be that the odometer didn't work. I pulled it apart, replaced the gear, remove and bypass the temp. comp. board, and swap a couple of bulbs while I'm back there. Also added a 52mm tachometer at the same time if that could be relevant. All is well for a few days.

Then, while driving, the speedometer starts dropping to zero and popping back up to speed. Intermittent problem. I fiddled with the connector and it seems to help. Also, banging on the top of the dash seemed to help. Now the speedometer and odometer refuse to work at all.

What'd I mess up? The electrical connector only goes on one way, but I must admit it's pretty cheesy. I'm thinking that I disturbed some connection, electrical or mechanical, down in the speedo when I had it apart for the gear. I recall adding a little petroleum jelly to replace the 22y/o dried up grease.

Also on the list is diagnosing a non-functional rear defroster (light doesn't come on). That should be pretty straightforward, but experiences you're willing to share are appreciated. Where's the relay?
