I tried to turn on my fan on the 1 setting and push the snowflake button to turn on the AC and no go. I turned it onto the second, third and fourth fan setting and it works fine when I push the button; the light comes on and gets cold, but on first it wont turn the light on and feels nothing is coming out. ANy suggestions???

 

Resistor block on the blower?

 

That or a bad switch. NO low speed.
