Central Flap Motor Error

[Rick_22]

I decided to scan my car the other day with my Foxwell scanner just to see if any errors showed up. The last time that I scanned it was sometime last fall and no errors were present. When I scanned it today the only error that I got was a central flap motor error. I tried clearing it but it keeps coming back. When I run the diagnostic checks on the other flaps they all have values which change.  When I run it on the central flap there are no values, so I take it that there is no power detected there? My climate control system seems to be working OK but not sure what the central flap does? I can get both warm and cold air? The only thing that I can think of is that I sent my climate control unit off this winter to have a new screen put in. For some reason they didn't send the exact unit back that I sent in. I know this because I had to tape the label back on the top of mine. I did take a photo of both and the numbers look the same. Where is this motor located and does anyone have any ideas what could cause this error, other than a bad motor?  Could I have received a bad climate control unit?  I don't see any specific fuses or relays for the central flap motor.  Is there something else to look for?

What code are you getting? And what year and model is the car?

[Rick_22]

1999 Boxster Base. The code is 27 when running the diagnostics for the heat/ac.

I'm afraid that code doesn't mean anything to me as fault codes typically have four digits.  Try scanning the car with a Porsche specific tool.
