My A/C Heat only works on high.. I know I need to replace something behind the dash, could anyone tell me what to replace or how much it costs?

 

I believe it is a fan speed resistor. Obviously your fan isnt working on its low-speed setting. I think resistor behind the dashboard, looks like a little square computer board kinda but with not as many little parts.

 

haha hope that ford stocks that so that i dont have a PIA getting one.

 

They should if its a decent sized Ford dealership. If not, they should be able to order one.

 

Just so you know the part was 22 bucks and the install took all of 5 minutes right under the glove box!
