Gauges don't work

My speedometer does not work. My gas gauge and temp gauge are still working though. I checked the fuse and it's fine. what is wrong!!!

I had this problem so I took my gauge cluster out and cleaned the contacts. It took about 15 minutes and my speedo has been working since.

You just lift the dash up a few inches then you'll see the phillips head screws to take out. I think there are 4 screws, pull out the gauge cluster, clean the contacts and put it back together.

Did your odometer stop working as well? If so, could be a bad speed sensor.
