A blown fuse can cause your fuel gauge and speedometer to stop working. Replace the fuse. The fuse can be found in the fuse box. The location of the fuse will be listed on the inside cover of the fuse box.
If both the speedometer and odometer stopped working it is probably the speed sensor in the transmission gone bad. If only the speedometer quit you may have to replace the dash cluster with a reconditioned unit.
Find a road with a "measured mile" and check it.
There is no cable, the speedo is run electronically.
The fan relay could be bad or the fan motor could be bad.
rpm and speedometer gauges not working 1995 Chevy silverado 2wd
There is no speedometer cable anymore, it's all electronic.
This question is very wide. But, I would suspect the speed sensor.
I have a 2004 Chevy Cavalier and there was an electrical problem in the dashboard. I had to have someone pull the entire thing out and re-wire--it cost me about $400.00. It started with my speedometer going out and then my rpm went out and so on. My mechanic told me that Chevy should have recalled this but didn't....
If the speedometer is not working but the odometer is, I would suspect the dash cluster is at fault. If both speedometer and odometer are not working I would suspect the speed sensor on the transmission is at fault.
If the speedometer is not working it probably needs a new speedometer cable. If the speedometer is actually broken either take it to as speedometer repair shop or replace it.
check the fuse box, could be that easy sorry... they are all on one fuse
