READ ANSWERCasey thank you for the quick response answering my question about the black foam pieces coming through the vents. My question is would you happen to know if there is only one flap to recover with the foam tape or are there two individual flaps. On the videos I watch they are only concerned with the one flap that you see through the heater core box.

Is there only one flap to recover?
READ ANSWERI own a 2006 997 Carrera S Aero and the problem just about every older Porsche has with the black foam spitting out the HVAC ducts. I’ve watched videos on how to repair with new foam tape on the blending flap but some people say to do one flap or are there two flaps to recover. I know the two ways to get to it by through the heater core compartment and through the center of the dash. Any advice on one or two flapd

I’ve also allocated 2k a month for upgrades and repairs over a 3 year period in an attempt to bring the car up to an 80-100K car. So, if I buy an original car and modify it, will t ...

Sunday 11/02/2025 | 2018 | 718 Boxster | Electronics
I just purchased a 718 Boxster. It did come with 2 fobs, but once I got it home it seems one of the fobs is not recognized. The buttons would sometimes work to lock, and unlock, but the fob will not start the car. I replaced the battery, but that didn't help. After awhile the alarm will start going off if I use the remote in any way. I noticed the red light on the fob just keeps flashing for a period of time. I eventually can stop the alarm, but I am afraid to use that remote going forward. I ...

READ ANSWERLCD on center gauge is dimming to nothing, where is the problem?
Friday 10/31/2025 | 2006 | Cayman S | Electronics
The large LCD in the center gauge began dimming towards the end of a 4 hour drive last night. This morning it worked fine again, just to turn all the way off shortly after. It doesn't have the typical "bleed" problem that these LCDs get, it just simply fades to nothing. Is the screen failing? That seems odd since it was bright and normal again this morning after the initial issue last night.
