A sound from the dashboard is not noise but a warning. Through the dashboard, the car’s system informs you whenever there is trouble down there. The sounds of clicking are one-of-a-kind because they indicate problems in areas that are fairly uncommon. Problems with the door engine, transmission system, and air conditioning are among the causes of dashboard clicking sounds. Although this is uncommon, incorrect weather settings can also cause of clicking noise in dashboard when car is off.
You should conduct scans and tests to confirm your suspicions before determining the cause and beginning repairs. A thorough manufacturer’s manual can be used to make a straightforward diagnosis, but you need to have a basic understanding of how cars work.

Causes of clicking noise in dashboard when car is off
1) Heater Motor Calibration
An innovative piece of equipment is your automobile’s heater, also known as an HVAC (heating, ventilation, and air conditioning) system. It has a lot more finesse than it appears. Heating/cooling and airflow are controlled by the system through the use of sensors, doors, and motors.
A computer could only manage to keep track of all the motor positions, temperatures, fan speeds, and dual-zone requests. All of it is managed by the HVAC control module, but for it to work properly, it needs precise readings of the blend door position.
Now and again the positions are miscounted, which causes sporadic engine initiation. The issue is resolved by recalibrating the system.
2) Faulty relay
Although every vehicle is unique, the majority of the time, the relays can be found in the fuse box under the hood. Knowing what these relays do in your vehicle is crucial. The primary undertaking of the hand-off changes assists with controlling the ongoing in the circuit. Switches are susceptible to damage and fire if there is no relay.
The air conditioner, headlights, and taillights, among other electrical components in your vehicle, will operate normally when the relay is functional. Additionally, the power supply magnet will transfer from the mains to the motor, resulting in the instrument panel making a loud noise. Additionally, if the dashboard is constantly connecting to the mains and disconnecting at high speed when connecting multiple times, dirt on the junctions may cause the dashboard to make clicking sounds.
3) Leak In Compression Cycle
The clicking noise is not always a problem. It may occur when you hear the compressor in your air conditioner turning on and off intermittently. When the air conditioner is running, you might hear a clicking sound in the dashboard of your car. However, if there is a leak in the compressor, you may also be able to hear the noise.
4) Damaged Battery
When starting the vehicle, the starter may make a clicking sound on the dashboard if it doesn’t get enough power from the battery. Additionally, if the alternator has developed a fault and is unable to recharge the battery, the issue may arise.
When the starter turns on and off, you’ll hear a constant clicking sound, and the engine might also misfire. One of the most typical symptoms of problems with the battery and alternator is engine misfiring.
How to Fix the Clicking Noise in Dashboard when Car is Off
After determining the source of the dashboard’s constant clicking sound. Continue toward the subsequent stage to take care of the issue.
Test/replace a blend door actuator
You need to go to the repair centre to reset the blend actuator if you hear a clicking sound under the driver’s side dash or a knocking sound from the dashboard. You can check this part on your own if you have mechanical experience. To begin, you must disconnect the car’s negative terminal.
If your vehicle has a radio code, make sure to write it down or, even better, be able to calibrate it. If you do not have a calibrator, you should take your vehicle to a mechanic.
Check if the AC is doing fine
To avoid an unsuccessful goose chase, it is essential to isolate the sound source before beginning any repairs. Because the refrigerant does not leave any traces, finding the area where the AC leaks are difficult to repair on your own.
The mechanic will provide you with the appropriate advice. The primary options for repair are simply replacing the leaking area or repairing it.
Apply Tape to lose areas
If you think that simply tightening the fasteners will not be sufficient, why not attach some double-sided tape to the screws.
This idea is best for parts that are hidden. It might need to be opened up completely, taped up with the loose parts, and then put back together. The tape and fasteners that have been tightened should hold for some time.
Be cautioned, this thought is tedious and requires a few abilities.
Change bad relays
Awful transfers are viewed as the explanation for your vehicle making a clicking commotion when off. Supplanting with another one is the main technique you can apply in this present circumstance. To determine whether the car’s relays are in good working order, you must use a multimeter.
When the relay is taken out of the fuse box, the multimeter is used to measure the DC voltage, and the switch in the cabin is turned on. First, make sure that there are 12 volts in all 85 positions in the fuse box, regardless of whether or not the relay is plugged in.
If not, make sure the right fuse has blown. Check that the switch allows current to flow to the relay if the fuse is intact.
Conclusion
Although not every little sound should set off alarms, it could indicate that something is wrong. You really won’t be able to do much to stop such dashboard clicking or knocking sounds. However, simply keeping up with your regular inspections is a good thing to do.
Maybe when you take your vehicle in for a straightforward “examination,” a specialist can see that something may be off with your dashboard. The sooner something is gotten, the sooner it tends to be fixed. This can set aside your cash, particularly if the issue can turn out to be more awful and more exorbitant assuming you delay.
Don’t hesitate to take your car to a trained mechanic for a checkup before the problem gets worse if the clicking and knocking sounds coming from your dashboard are getting worse or if you’ve noticed other issues with your HVAC system.
