Speedo and Odometer don't work

[MattE30]

A couple weeks ago, my speedo jumped up and down when i let off the gas and pushed the gas. Now it doesn't work, so my mpg meter and odometer don't work either. I had different size wheels on the back by 6 millimeter for about a week and a half, which I had to because I got a flat. Now I have all the same wheels on. I know different size wheels is bad, so could this have caused the speedo to stop working (since the speedo gets it's reading from the diff)?

didi you check the fuses?

hit the dash a few times, it may come back on<--temporary fix. Mine just started doing this and I need to fix it right. I think the connectors need to be taken out and put back in, or there is a loose ground somewhere. Perhaps it is a common problem on our gage clusters. I have a motometer by the way.

Nope, the speedo doesn't care what size tires you're running. :P

But seriously, pull out the gauge cluster and check all the connections. There is probably sometthing loose back there. If it's not that, it may be the sensor itself on the differential.
Pretty common problem with these cars.

Thanks a lot. I was thinking the sensor could be bad so I might as well get a new one.
