Why are there water marks on the dashboard of the XRV when the air conditioner is turned on?
2 Answers
It may be caused by excessive temperature difference, where hot air meets cold surfaces and creates water marks. Function: It is used to adjust and control the temperature, humidity, air cleanliness, and air flow inside the vehicle cabin to the optimal state, providing a comfortable riding environment for passengers, reducing travel fatigue, creating good working conditions for the driver, and playing an important role in ensuring safe driving as a ventilation device. Layout: The layout involves assembling the evaporator, heater radiator, centrifugal blower, control mechanism, etc., together, which is called the air conditioner assembly. Current air conditioners are divided into mechanical air conditioners and automatic air conditioners.
The other day when I was driving my XR-V with the AC cranked up, I got quite a shock seeing water stains appear on the dashboard. I wondered what could be causing this. After some research, I found it's usually caused by AC condensation—on hot days when the cabin air is humid, the AC cooling makes the dashboard cold, causing moisture to condense into droplets that accumulate and leave stains. Another possibility is a clogged AC drain pipe preventing proper water drainage, causing it to backflow under the dashboard and leave marks over time. The worst-case scenario would be compromised body sealing, like a sunroof leak or aging windshield sealant allowing water seepage. This needs immediate attention as accumulated water could lead to electrical shorts—super dangerous while driving! Later, I learned to check the drain holes—found the AC drain pipe near the trunk area and cleared it with a wire. Then I wiped the dashboard dry and placed a dehumidifier box in the car to prevent moisture buildup. Regular AC system maintenance is crucial—don’t wait until something goes wrong to regret it.
