I have had issues with the fan not turning on and not blowing any heat when it is humid or raining. If it's cold it usually works fine. There is still heat but the the fan doesn't come on at any speed. I brought it to my local Dealership on Monday, they said they could not find anything wrong with it, but said it had lots of debris so they vacuumed and changed the cabin filter for $220. The next morning the fan didn't turn on right away but it did after about 20 seconds. I figured that the problem was not resolved but was willing to wait and see. On Wed the problem was back and the heater fan wasn't working again, I brought it back to the dealership.

They said they found the problem and I needed a blower motor, they said that it was the problem. They changed it and it was ready today (Friday) I paid the $1550 charge, got in my car and guess what... the problem is still not solved. The mechanic didn't seem to know what happened but said it worked an hour earlier. So it was almost closing and I was so pissed off and I just told them to fix it. They clearly don't know what they are doing and I just spent almost $1800 for nothing because I am no closer to a solution then I was.

It may work tomorrow if the weather is dry and next time it's humid it will not work again. Not sure what to do but I think the mechanics just fixed something by guessing without really knowing what was wrong.

Does it work in the Max setting?
Maybe resistor?
