I have a 2006 F350 super cab diesel 6.0L 4wd. My fan/blower only runs on high. I have checked all fuses and relay, but have been told that there is a blower resistor. Where is it located and could this be the cause for this problem.

Hello,

It does sound like the issue is a bad blower motor resistor.
Typically, when the blower resistor fails it only allows one speed and no other setting functions.

That resistor is located in the blower motor housing. Which located on the passenger side fire wall. This can be access from under the hood.

I have attached diagrams for your reference.

Please let me know if you have any questions.
Thank you.
