Hi, Can anyone shine a light on my heater/climate fault ? The car is an a4 2002 b5 tdi. The temp gauge only rises to around 70 , econ light on dash will not switch off , fan is on from start up, and the real poser , both settings on hi on the climate. Passenger side all vents hot air, drivers side all vents cold air . had a diagnostic which shows r/hand flap acctuator fault. Took out glove box and found motors ok . took out drivers lower shelf but no sign of any motors.

Do all the motors on n/s operate all vents ?
Can thermostat be faulty ?

Really need some help people, getting cool out there ! Thanks in advance.

Chris A4.
