A couple weeks ago, all of a sudden, the AC started working improperly in the AUTO mode. Basically, it works fine on the freeway, when cruising. As soon as i stop or when i am driving slowly in traffice the AC starts blowing very intermittently. The air blows hard sometimes and then slows down and then blows harder again. The difference is drastic and sudden, and it never did this before.

I researched the messages here and looks like this is caused by a faulty resistor. My car is still under warranty. Before i take it in to check it out, wanted to check if anybody has had similar problems and if the part is covered under warranty.

P.S: I have a 2001 330i
