Common reasons why the car dashboard may produce clicking noise

Various factors result in clicking noise, and some require a professional mechanic. The main thing is to fully know all parts of the car and understand how they are functioning correctly. It will make it easier for you to solve the issue, and here are some of the causes.

1. Heater control failing to function

The heater control is essential in regulating the air passing into and out of the car, and it cannot work without some thermostat sensors. Sometimes, the heater control may not be correctly aligned, forcing the engine to start.

2. A faulty stepper motor

A stepper motor is an essential part that aids in the car functioning correctly, and sometimes, it may be distorted, resulting in the emission of loud noise in the dashboard. Many of the stepper motors are the main reason why your car keeps making noise once they become faulty. Once you experience such, it is important to fix the motor immediately.

3. A bad relay

The relay is a component within the car responsible for regulating the circuit since a minimum amp circuit is necessary for controlling a heavy circuit, and some of the circuits include; lights, starting motor, among others.

In most cases, the power supply magnet usually moves from the power supply source to the engine forcing the dashboard to emit noise. Also, the dirt composition on the joint points can make the dashboard emit a very loud noise, especially if it keeps connecting and disconnecting at a high rate when connected to the power source several times.
