Blower Control not working properly

Hi, I have a 03 F250 with a 6.0 and the blower control is the same speed when I select the 2nd and 3rd speeds. Just need to know if it is the actual blower or is there something else that should be replaced, and if so how easy is it to do.

Thanks

Honestly im not sure about these superduties, but on the obs trucks there is a transistor that fries under the hood and you replace that and your blower speeds are fixed

BLOWER SPEEDS

As long as you do not have Electronic Climate Control, your problem is either a burned out resistor, or a bad blower speed switch.The resistor is mounted just to the right of the blower motor in the engine compartment. Remove it, and if it has burned out, it should be easy to see. It is available thru Ford, and also some aftermarket companies through your local auto parts store.

I had a similar issue when I came back from deployment and asked about this. I got some great answers and got it fixed with just a simple $25 part. Here is the link to the part you will need to fix this. Hope you have as much luck as I did.
