    digital odometer

    I have read some other threads that have been all over the place with problems with the digital dash but I have a 90 Brougham and just the odometer glitches; everything else works great. Sometimes its right on with the mileage which is only around 60,000 but alot of times it starts going crazy with a whole bunch of higher numbers, other times it just reads ERROR. I want to sell the car and i figured it would probably be good to figure this out before then. Any tips/suggestions?

    Its gone bad. I havent seen any type of repair available for these and they go out pretty often. I took a bad one apart and it was full of dust but I could see anything wrong with it. Might try taking it to a small electronics shop with a wiring diagram.

    Many years ago I had a 90 with the exact same problem. A local shop made an extremely simple repair that, in my case, fixed the problem. On the transmission, the speedo cable attaches on the side. He said he simply took the cable off ( it unscrews like a light bulb) and cleaned and lubricated the cable where it enters the transmission. He told me he had fixed several cars with that exact problem that way and it worked. Keep in mind this was maybe 10 years ago, so maybe your problem is different, but it is sure a cheap and easy first step. Good luck.

    The problem is in the digital dash itself like csbuckn said. There are a few places around that fix them and the dealer can do it too but the price isn't worth it.
