When my air is blowing, the first and second air powers don't work, but my third and fourth powers do. So I always have to blast my air!

Air Flow question
By powers I mean the setting for how much air I want blowing.
Happens with heat and AC.
Sounds like a bad fan speed selector switch.
I did a quick search and also found that the fan motor resistor often goes bad a $20 part. Info from the web: The resister is bolted in place beside the blower motor, which is located under the dash on the passenger side of the car. It is easier to access if you recline the passenger seat and lie down on it with your head on the floor mat, looking up under the dash. Remove the blower motor first, if you want easier access to the resister. I think both are mounted with 5.5mm socket size bolts. Most people may not have this size socket, but it is worth going to the store to buy one before you begin. An extension of about 6 inches and a flexible socket joint will make things easier. The whole operation should take less than half an hour.
