407 misting

The wife wanted to take the car out for a spin tonight, so we drove to Putrajaya for a joyride. As you can see from the picture above, there was a huge amount of misting on the windscreens. This is apparently not uncommon, as there have been a number of forum members who have complained about this.

 

The reason for the misting is that there is long air vent at the top front of the dashboard used to as part of the climate control system to improve air distribution. While one can control the aircond blower so that only the front and leg vents are activated, there is still a small amount of air that escapes from the top vent. This creates condensation when the outside and the cabin temperature is uneven.

 

Actually, having owned several continental vehicles prior to this, I am familiar with this problem. However, it seems a little aggravated in the 407.

 

Having asked KS Auto before, they are able to create a fix by taping over the vent and/or placing a cardboard cut out to prevent the air from escaping. I may decide to do this too but am afraid that this may impair the aircond system in the long run.

 

Am going to try some anti-mist solutions specifically a liquid formula available from CarPlan. Will update once I attempted that fix and report on the results.
