I have a 2002 Audi A4 3.0 Quattro and I was curious how you can control both sides of the A/C or Heater, currently if i want the car heater on i have to turn both sides up which is kind of annoying, I know at one point if i changed the drivers side to HI then both would change, but not sure how to do that again if it is possible? Any suggestions??

 

just hold the auto button over the control u want. it will allow u to control both sides.

 

Thanks I knew it was something simple. Appreciate it!

 

anytime.
