How do I turn on the heat in my Acura RDX?

Turning on the Heat in Acura RDX
To turn on the heat in your Acura RDX, you can follow these steps:
1. Check Coolant Level: If the heater is not working and only cold air is blowing, it could be due to low coolant levels. The heater core requires hot coolant to function properly. Ensure that the coolant level is adequate to allow hot coolant to enter the heater core.
2. Use Climate Control: Press the up arrow on the center control stack and raise the temperature on the screen to command the blend door and heater valve to turn on. Setting the temperature to a higher level should activate the heat.
3. Check Blend Door Actuator: If the blend door actuator fails to fully open the blend door towards the heater core, it can result in poor heating performance. A clicking sound or unusual noise coming from under the dashboard could indicate a faulty blend door actuator.
4. Inspect Water Pump and Serpentine Belt: If the heat starts to blow hot for a few seconds and then turns cold, it could be an indication of a bad water pump or low coolant. A failing serpentine belt going to the water pump can also cause the heater to blow cold air.
5. Avoid Using A/C Compressor: In winter, it’s advisable to turn off the A/C compressor to prevent excessive fuel consumption. Using the heater without the compressor can help conserve gas.
If these steps do not resolve the issue, it may be necessary to consult a professional mechanic to diagnose and address the problem with the heater in your Acura RDX.
Remember to always prioritize safety and consult the vehicle’s manual for specific instructions related to your Acura RDX model.
