The climate control system in a Nissan Maxima allows you to control the temperature, airflow, and other climate functions in your vehicle’s cabin.
Sometimes, you may need to perform a reset of the climate control system if certain functions stops working properly or if error messages show up on your display screen.
Resetting can often restore the functionality.
Here are the steps to reset the climate control system in a Nissan Maxima.

Locate the Reset Button for the Climate Control System
The first step is to locate the reset button which is specifically tied to resetting the climate control system.
Depending on your Nissan Maxima model year, the reset button could be in one of a few locations:
Mid 2000s Models (2002-2008)
- With the car powered on, hold down the AC button for 10-20 seconds until the display screen goes blank.
- This resets the whole climate control module.
Recent Models (2009 and above)
- Find the button that has the circular “power” icon next to your climate control display.
- Depress that reset button for 10+ seconds to reset the climate control system.
Once you have located the appropriate climate control reset button, here is the overall procedure to do the reset:
- Make sure your Nissan Maxima’s ignition switch is in the “On” position as you are able to power on your screens and buttons.
Note: You don’t need to start the vehicle.
- Hold down the climate control reset button for at least 10 seconds and up to 20 seconds.
- Don’t just quickly press it. If it begins flashing, continue holding.
- The climate control display screen (if equipped) should go completely blank when the reset is complete.
- Turn off and on your ignition switch to exit the service test mode if you are still seeing display codes.
- Test out your climate control system functions like adjusting the temperature, changing the fan speed, redirecting the vents etc. to confirm the normal operations.
- If any of these issues persist, seek for a Nissan service department.
Troubleshooting the Common Climate Control Problems
If resetting your Nissan Maxima’s climate control system does not restore the proper functionality, there may be an underlying mechanical or electrical issue.
Here are some of the most common climate control problems and troubleshooting tips:
Display Screen is Blank
- Make sure the display screen is not just switched off through your settings. Try adjusting the brightness.
- Check the fuses – there may be a blown fuse for the climate control display that needs replacement.
- Inspect the connections that leads to screen and climate control unit for corrosion or damage.
Fan Speed Is Inconsistent/Unresponsive
- Fan issues can be caused by blower motor failure or a wiring problem. Test the blower motor directly by connecting to the power to overcome this issue.
- The resistor that controls the fan speed may also need replacements if certain speeds do not work.
Temperature Regulation Is Inaccurate
- Faulty thermistor sensors can provide incorrect temp readings to the system. These can be tested and replaced if necessary.
- Low refrigerant levels can prevent the proper heating or cooling. Therefore, have the A/C system inspected for leaks.
Strange Smells From Vents
- Moisture breeding of mold/mildew in the AC evaporator case can cause foul vent smells. Evaporator may need cleaning and disinfecting if issue persists.
- A musty smell can also indicate leaks by allowing water into interior HVAC components.
