Front windows fogging up, FL2 TD4

Akroni · Oct 23, 2024

Hi all,

so I've noticed that my windshield, driver and passenger door windows fog up randomly. So far this has occurred in both high and low speeds and can be quite dangerous during rush hour. Is there maybe some drains I should check or is my AC falling apart? Outside temperature has been around 8-10 degrees Celcius and AC on auto set to 22 degrees.

Sounds like you have water leak into the car somewhere causing condensation. Use the air con this time of year to keep windows clear, not just in the summer.

I keep air con on all year around and still the windows have gotten foggy randomly these past couple of weeks.

Will have to look for possible leaks, would be great if somebody could point me to "normal" failure points of FL2.

Check the ac drains aren't blocked underneath

Google tells me the high level brake light let's water in.
Infact there are many topics and videos about water ingress on a FL2

Check the cabin filter too. My previous Ford Transit kept fogging up and found the cabin filter was the culprit (van is maintained by a company and were shaving money).

I tried this:

Only a small amount of water came out, less than in the video. Tried to blow the rest of the drain open, not sure if it worked, but I guess we'll see the results in the coming days.
