It’s vital for drivers to have access to a wide range of information while behind the wheel. This includes vehicle speed, RPM, fuel level, coolant temperature and much more. The information desired is shown for the driver on gauges – the fuel gauge, the speedometer, the tachometer, etc. This is the instrument cluster. Like many other elements of your vehicle, the modern instrument cluster is electronic, and requires voltage in order to function. The instrument cluster consumes less power than batteries do (Batteries use around six volts).
The instrument cluster voltage regulator makes sure that the right amount of voltage is supplied. Voltage regulator failure is relatively rare, but not unheard of.
Facts to Note:
Instrument cluster voltage regulator failure means that your gauges will not function.
The voltage regulator is made as part of the entire instrument cluster, meaning that the whole part must be changed.
How to Fix:
The battery is disconnected and instrument cluster detached
The defective instrument cluster voltage regulator is detached
The new instrument cluster voltage regulator is fixed
The instrument cluster is reinstalled and the battery reconnected
The engine is started and the gauges are checked for proper operation
Given the fact that you must have access to the information provided by your instrument cluster, failure of the voltage regulator is unwanted. Devoid of an operational instrument cluster, you will not know the fuel level, vehicle speed, or the temperature of your engine coolant. We commend having the problem analyzed by your expert mechanics straightaway.
Common symptoms indicating you may need to change the Instrument Voltage Regulator:
Gauges are totally inoperable
Gauges operate erratically
Importance of this service:
Replacing your failed instrument cluster voltage regulator is very vital. Have your vehicle diagnosed expediently as other problems can cause the same symptoms as instrument cluster voltage regulator failure.
