Hello !
I found a link to you via the internet & Rennlist and am hoping you can answer a Porsche question for me.

I live in Texas (99 degrees her today @ 4:45pm) and I own a triple black 1985 911 Carrera Cabriolet. When I first start my Porsche the AC blows nice cold air, but when the car warms up I presume the heat exchangers then start blowing hot air in to the cabin, as the original 25 year old heater doors/flaps are not fully closed, thus rendering the effectiveness of the AC.

Is there any effective way to get the door/flap to fully close off the hot air from the heat exchangers ?

While it would be great to have a functioning cold AC for the Texas summer, I would prefer to not lose my heater in the winter either.

Thanks and PLS advise – JIM
