Not sure if this is in the correct forum?
I have just bought this car 316i 03 plate E46.
I am having problems with the climate control/ heater. The previous owner has taken out a 'knob' control system and put the 'button system with centre LCD' control system.
It works fine, but the air flow direction is completely wrong? it always wants to push the air to the feet vents? and middle vents? it will not push air through the windscreen vent even though i have selected it?
Is there a chance he has messed up the connectors in the back? or just the units faulty?
Also can this be done and working correctly? changing the 'knob' control system and put the 'button system with centre LCD' control system in?
