What is the reason for the AC light not working in Nissan Tiida's air conditioning?
2 Answers
Nissan Tiida's air conditioning AC light not working is due to the power fuse of the air conditioning switch being broken, which does not send a signal to the vehicle's compressor, naturally preventing it from cooling. Replacing the AC fuse located in the engine compartment's fuse box will resolve the issue. Function of the AC Button: The AC button is the switch for the air conditioning compressor. In summer, when using the air conditioning, the AC button must be turned on to activate the cold air. On the other hand, the warm air simply utilizes the internal heat circulation of the car and does not require the activation of the air conditioning compressor. Therefore, to use the warm air, you only need to adjust the air conditioning button without turning on the AC switch. Warm Air: The warm air comes from the heat generated by the engine during operation. When the engine's cooling system dissipates heat from the engine, the fan directs this heat into the car to create warm air. When the warm air is not in use, the fan stops, the heat vent closes, and the dissipated heat is completely released into the atmosphere.
As a car owner, I've been driving a Nissan Tiida for several years, and the AC light not working can be quite annoying. The most common issues are a burnt-out bulb or poor contact in the switch, just like a household bulb that fails after prolonged use. I've encountered this myself—first, check the fuse box (usually under a small cover on the left side of the cockpit). If the fuse is blown, try replacing it with a new one. Alternatively, the wiring might have aged, especially the control circuit from the switch to the headlights, where connections can loosen. If you're not familiar with electrical circuits, avoid dismantling the panel haphazardly—just do a simple check to prevent further issues. It's best to drive to a repair shop and let a mechanic test it with tools to avoid affecting the AC cooling function. Regularly keep moisture away from the circuit board, as maintaining dryness can reduce malfunctions. Addressing minor issues promptly ensures safer driving.
