406 temperature indicator is not working please support

Friends 406 m 3 pieces of solid and solid indicators, but the vehicle does not show any temperature.

If the clients are intact, the indicator may be problematic. it is necessary to have the electronics removed

If too few ticks try to move, the gauge or motor of the indicator is defective.

It does just that, it plays a little, the indicator then stays in place

go to a service that can perform computerized testing (with a planetary program), do a dashboard test, if the hands are working smoothly, there is a problem with the installation or the consumers, if the indicator does not work, the fault will be found directly.
