The a/c control head is the "master" control unit, if one of the slave units don't work it will put the master unit aka the a/c control head in econ/limp mode.
IN ENGLISH YOUR HEATER OR A/C WON'T WORK!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Get you fvcking fault codes checked. [:@]

 

chill man, im just curious, how much do you think that will cost if i take it to the dealers to have it fixed?

 

???

 

1 hour diagnosis, anywhere from $80-$130 depending on what state you are in.

 

It could be buttons on the controls. Make sure that all the buttons move in and out smoothly.

If the buttons aren't stuck, it may be either the unit itself or one of the flap valve motors. Checking with a vagcom of the HVAC will help find the problem

 

ok thanks david and auditech.
