hello, i recently bought 1995 a4, and i have a question about climate code menu.
I have this climate

when i enter menu and select 2 or 3 then both show 0.
Does it show that for anyone or i should see interior temps?


2 Digital value of Interior Temperature Sensor, in Headliner (G 86)
3 Digital value of Interior Temperature Sensor, in Instrument Panel (G 56)

4,5,6 work for me and i see temps.

4 Digital value of Fresh Air Intake Duct Temperature Sensor (G 89)
5 Digital value of Outside Air (Ambient) Temperature Sensor (G 17), front
6 Digital value of Outside Air (Ambient) Temperature Sensor

Where is headliner sensor located?
What does servo motor for dynamic pressure flap do and when does it activate?

It i winter and i really needed defrost to work , yesterday i took climate module off and used my lab power supply to connector behind climate modul to get all motors back and foward , i used 20v and limited amps to 0,1 so if it goes to final position no damage is done , i got 3 motors moving now and put all together but now 1 motor still failed and defrsot wont work as all goes to legs, i guess il open it up again. seems that climate controller gives very low amps to motors so if they are not used for long time iw wont supply enough to move.
