I haven't been around in a while, too cold to work on the car and busy with other stuff...anyway...
Yesterday my speedometer started acting up. From what I've found online, most failures are of the "working/not working" variety, and mainly caused by a failing speed sensor or damaged wire running from it to the dashboard. My problem is that the speedometer is working, but not reading properly. At low speeds, it reads way too low, when it always used to be a bit fast. At about "30" on the face, it starts to move unusually fast, then jumps straight from 50 to 60 (I can be doing 45 and it will say 60). Above 60 it settles down and works more normally. Going down, however, it sticks badly between 60 and 35 on the face - the needle will sit at 60, then shoot downwards when the speed drops down to around 30. It's been cold here, but the problems remain the same even when the car is well-heated from driving around for a while. I've never seen a gauge in any car act like this. Any ideas on what might be causing it, and how to repair the problem?
