Heater woes - worse after flap repair

[millerchris85]

I recently got a 996 911 and immediately noticed the heater was weak.

 

I repaired the foam on the heater flap, and it is now worse...

 

In an effort to check the solenoid, I disconnected it from the flap and moved the flap by hand, and it gave me a slight change but not much.

 

I’ve tried multiple test drives with the bleeder valve open, and both heater core lines are warm to the touch, so I think it is bled.

 

Not sure where to go from here.  Possibly the control unit, or possibly the flap is not installed correctly? If the core is warm and I manually move the flap, shouldn’t I be able to get heat?  The flap has little rotation, maybe 60 degrees at most.

Resolved - I accidentally installed the flap backwards.

That's interesting! I'm surprised this is possible, but perhaps I shouldn't be... I always take photo's when taking things apart...😉

I did!  But not well enough, clearly.

 

This video helped me confirm the orientation.

 

The door closer to the radio is also foam-less, but I am not sure if I want to cut a hole in the heater box to get to it.
