A while ago I posted about how the fans would not turn on when the speed control was set to 1.

Now out of the blue the fans will not kick on when it is at 1 or 2. The fans only turn on at settings 3 and up.

I have tested all methods of heat/air distribution on the car and I am positive that they do not turn on. I used to think setting 1 was to low and it just was very weak. Now I am for sure because 2 is also dead.

What could be causing this? It works fine on 3. The heat is strong. No weird noises or anything.

Thanks for the help!
