When I run the AC on manual and use only the center vents there is NO air coming out of the windshield vents.
Leading evidence: 'Run ac' (no explicit attributable resolution; this is a reported action or suggestion). Across 1 matching discussions, The most frequently discussed action is 'Check ac drain' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.

I set my AC to center dash vents only and never have any condensation.

Suggestion · Original poster
condensation outside the windshield due to the fact that cold air always comes out of windshield vents regardless to whatever setting the a/c is on,,

tried every single setting,, airflow may get reduced,, but never stops,,

Suggestion
That procedure blocks out the automatic use of that outflow path and now the windshield will not be inadvertently cooled to dewpoint by the CHILLED A/C airflow.
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

anyone found a solution for windshield condensation in summer nights?
2 days ago,, i found some water drops on my shoe toe which i believe came from behind the dashboard due to a/c condensation,, is that common?
Dyu mean condensation inside or outside the windshield? Either way, no water should drip inside the car. put the blower on the inside of the windshield to clear condensation.
I set my AC to center dash vents only and never have any condensation. If your condensation is on the outside it should not be leaking to the inside in any case. Maybe a drain line is clogged up somewhere?
All I can say is the A/C in my 04 40th AE is the best and coldest (and has a fast airflow) A/C I have had in any of my cars. One area that was once a sore spot for Porsche in the air cooled world has come full circle and is one of the best I have experienced!
Ok just got back from driving my 996 this morning. When I run the AC on manual and use only the center vents there is NO air coming out of the windshield vents. When I click the Auto button the air does start coming out the windshield vents but then after switching to center vent only the air stops coming out of the top vents. So it appears to me that you have a vent malfunction. Steve my AC also is very cold and really kicks *** for an 11 year old car.
Porsche has somewhat of an anomalous design with regards to the climate control
AUTOMATIC
design mode.
Once the cabin atmosphere declines to fairly nearby your temperature setpoint the system automatically switches to opening ALL outflow ducts, windshield, dash, footwell(***).....WINDSHIELD...!!??
On a hot/humid day, or more likely early evening as the air cools and the RH rises, the resultant cooling of the windshield will often result in exterior windshield fogging. I first had this happen crossing Alabama one evening just after driving through a rainstorm, it was so sudden that my first instinct was to pull to the shoulder since I now had minimum forward vision.
The best solution is to first select, manually select, the windshield flow mode (NOT DEFROST MODE!), and then immediately deselect same. That procedure blocks out the automatic use of that outflow path and now the windshield will not be inadvertently cooled to dewpoint by the CHILLED A/C airflow.
*** My best guess is that this is done in order to more widely disperse the COOL system outflow, allowing an overall lower, less intrusive, blower speed, and lower velocity, less discomforting CHILLED airflow to the face and upper body.
Lessons from Lexus, I guess.
Also check that you have water draining out of the car (condenser drain).
When the car is running and the airconditioner is on.
Car climate control is not set on recirculate? Right?
I get the outside windshield condensation on humid or foggy nights.
Bring the temperature up on the climate control to about the dew point outside and it will evaporate, especially upon driving, also the wipers will take off the little bit there til you get going, and the temperature goes up on the winshield. Then take the airflow off of the windshield and you should be able to drop your climate control temp, it may come back if you really drop the temp a lot.
Are you down south or in a very warm area?
The issue of condensation on the outside of the windshield can be easily avoided via being certain sure there is no COOLING airflow from the windshield defrost/defog/demist ducts.
