Hoping someone can please help with a diagnosis. Warm air only when air cons on.
2001 Audi A4 1.9 tdi 130
Noticed so far....
Pressing Econ button turns the red light on, press again and it turns it off
Smaller Aircon fan under bonnet not running
Fuses on drivers side are fine (cant find any other fuse box near the battery as per some models)
Aircon pipe (silver) is not getting cold
No drop in revs (my wifes Audis revs dont drop either but her aircon works)
No Vagcom or Snap on codes
Thanks for all suggestions in advance.
