Anyone know where the evaporator condensate drain exits the body of the car and drips?

It's not to be confused with the fuel filler door drain that is directly below the fuel door at the back of the wheel well.

I've located where the tube connects to the bottom of the evaporator housing under the dash, just need to know where this tube exits the body.

I don't know the exact location on the underside of the car, but others here have said that the condensate drains into the front cover under the car and either evaporates or drains from there. I suspect you could find the end if you removed that cover.

The Cayman and Boxster have very little condensation. Very small cabin to cool.
Agree with TMc993. The condensation drips on the skid plate (under carriage).
The only time I notice water dripping is when I am backing out of a steep driveway during the summer.
While backing down a driveway, the condensation will roll off the skid plate.
Otherwise, I rarely see water on concrete.

The condensate drips down upon the unterbodenverkliedung and flies away when you drive.

Good luck.

I do appreciate the humor but I’m looking for very specific info here. I know it drains under the car. I have taken the forward under body pan off (the one under the gas tank and power steering rack). I don’t see an exit from the body shell for this drain anywhere under this particular pan.

A Porsche Service Advisor or Manager should be able to tell you as I think cleaning out all drains is a part of a major maintenance. Might be worth a tel call?

Waiting for a SA to call me back after he consults with a tech.... Interesting this little drain outlet's precise location is such a mystery.

I ask a tech about this.

I said, "any drains in the front?''

He said, "On the 981 Boxster/Cayman, everything is open in the front.
There is really NO NEED for drains or tubing to direct water. You don't have to worry about
anything clogging in the front of that platform.''

Maybe there is a tube out of the firewall for a condenser?

But, there is NO tube hanging down.

Hope this helps some.

I did hear back from a very experienced tech at a large Porsche dealership in DFW area who has done work on my car, message relayed through the service advisor I contacted there.

His description of where this drain was located didn't exactly help. He said to pull the center underbody panel off, the one under the seat area that covers the tunnel where the coolant pipes pass through. Said there would be four plastic tubes that look pretty much alike running pretty much together and one of them would terminate in this area and is the evaporator drain. No such four plastic tubes. There were three, but only two looked similar and the third one terminated such that it appeared cut off. It was about 18mm in diameter, much larger than the other two plastic tubes running in this area. So as I continued looking around the area where this underbody panel covers things, I found the evaporator drain. It is about exactly where the right seat passenger's left heel would be (North America market, left-hand driver cars). The two photos show it, one looking forward to the right front wheel for orientation.

Thank you for sharing with all of us so we now know where it is located.
