Likely a bad ground in the relay
why would a speedometer stop working on a Mazda
got the same exact problem.
Sounds like (& usually is) bad sending unit in tank.
Get to a shop quick.
We need to know which gauge stopped working.
It is probably your fuel sending unit gone bad. Have seen multiple posts on this problem.
The most common reason for a 1996 Chrysler Cirrus odometer and RPM gauge to stop working is a fuse. If the fuse is removed from the dash and replaced, often times the odometer and RPM gauge will begin working.
A faulty temperature sensor, a wiring issue, or a blown fuse could cause a temperature gauge to stop working. It could also be due to a malfunction in the gauge itself.
Usually a faulty sending unit.
There are several reasons why a gas gauge could stop working. A short in the wire from the sending unit could be the culprit. The computer that controls the dashboard gauges could be going out.
It could be the fuse, but mine is because the floater that measures for the gauge is stuck.
while driving the rpm gauge work perfect, when start accelerating the rpm can not exceed 3 with interruption in the engine
