Cayenne TT- condensation bottom windshield

Recommended Posts

My boys call it a mustache. It is very humid here in Florida at this time of year and I get a condensation cloud on the outside of the bottom of the windshield where the cooling vents are blowing AC inside the car. Any ideas how I can stop this other than by turning off the AC?

I get the same thing in NJ.. it's because for some reason Porsche leaves the defroster vents partly open when in automatic mode. Try switching from auto mode and just turn the face-level vents on.. that seems to help for me.

Thanks Don,

It isnt really a problem just annoying. I wondered if there is a setting on the AC or vent control I hadnt found.

I have the same thing but it's on the outside where the humidity is, windscreen wipers clear it.

I get this on the inside of the screen and side windows when its raining, as if the auto A/C cant cope. If i change the A/C to manual and increase the fan speed quite a lot it helps but doesn't really clear it.

Surely that's not normal, anyone any idea what the problem is?

It doesn't happen when its a dry day, only when its raining.

You may want to check under your front carpets, and check your AC drain tube.. sounds as if there is excess moisture in your truck, and when the humidity is up it's condensing on the cold windshield. Quick way to remove it - hit the defogger button (which turns heat full up and fan full up with AC compressor on, directing the output at the windshield.)

I would even consider, let check the AC system wheter there is enough refrigerant in the system.

Instruction on checking and clearing the drains has been covered here many times. Please do a search.
