Hello,

Sorry if this is posted in the wrong area as this is my first time here. I have a quick question....... I just purchased a used 2009 A4 with the auto 3 zone climate control. I usually keep it set at 68 and leave it on auto. The past few days I've noticed that when i get in my car the blower will kick on sometimes, and other times there's as much as a 20 min delay. During that 20 min the temp in the car clearly isn't close to 68 so it should be on. the thing that makes me nervous is when the blower is not responding I will switch it to manual mode and still nothing happens for a while. The car is fully warmed up and the temp gauge is where it should be. this seems to happen during the day after the car has been drive for a while. I live in a cold climate so quite often I'll start my car and let it run for a few minutes and the blower will come on right away. other times I'll make a stop, run into a store and when i come out it will be cold in the car but the heat won't come on for while.......Any idea what this could be?
