MOISTURE IN THE CABIN OF THE CAR

1999 Nissan Altima

Interior problem
1999 Nissan Altima 4 cyl Two Wheel Drive Manual 145000 miles

Moisture seems to accumulate in the cabin of our 1999 Altima. When it get cold, we have to scrap the inside of our windows. Do you have any ideas were we can start looking for leaks?

Hi Kay,

Thank you for the donation.

Star by flipping up the carpets on all sides to see which is wet or damp.

If it is from front passenger side, check if the A/C evaporator drain hose is plugged or detached. If you have coolant losses, then it could be due to leaks in the heater core, leaks might get to driver sid as well.

Next to check would be door trims cover. Behind the door panels are plastic weather proof seal which would allow water to get into the cabin if they are not properly sealed.

If any water accumulatingpoints are encountered, with carpets flipped up, use a garden hose to test for leaks, starting at the lowest point of the area near it. Visually inspect for leaks and repair accordingly.
