So the A/C was a bit of mystery to me at first. I would set the temp to 66 in auto but would still be hot. Than I realized when in auto mode the fan display switch is actually now a Limiter switch to high the system can turn up the fan. Mine seemed like it was set to two in auto mode and like in most cars i would leave it there thinking in auto mode it would adjust accordingly. What i realized is that you have to leave it in the highest position for the system to have full fan control in auto mode. So weird. So if you press auto and see that the fan is on two, bump it up to 4 and the fan will be able to blow max a/r when need be and reduce down to low when not. If you leave it in the middle then it will try to keep the temp but wont blow as hard. Now I have it set at 72 it works great in auto.
