hi
I joined just now when i see this subject.
this morning i install digital ac control for my ( AURION ) CAMRY.
only u need this part name ( AMPLIFIER ASSY, AIR CONDITIONER ) like this one

this is the digrame
which is Special for the digital ac control including the cotrol.
note: the digital and the 3 knob are the same shape but the diffrant inside.
i faces 2 problems :
1- the duel not working for the driver and passenger if u adjust one the other will change.
2- the temp. u can not adjust the temp. only hot or cooled. if change the temp. from lo which is cool to f.ex. 19 u will have hot .
Now the question is?
how can we fix this. is it only Programming ? if yes how ? if not what do we have to do ?
if u want to see the digital ac control on my car see the linke
