Help! A/C Blower STUCK on MAX

[BIGBLUE777]

Hello all, first time poster here, though I view quite frequently.....:Cheer:

Anyhow, Im hoping someone could help me out with an A/C blower issue: Yesterday afternoon I had the A/C blower on MAX for about 15 minutes or so and when I went to lower the blower speed, it stayed stuck on max...:doh:
I tried everything...checked all the fuses involved, including power distribution panel in engine bay, all vacuum hoses..hell, I even disconnected the batteries, but all to no avail. Regardless, whether A/C is on or off, or even if the key is turned on WITHOUT the engine running, the Blower motor is haulin azz at MAX speed! :bang

Somewhere, the blower motor is getting power for max speed... ??

I GREATLY appreciate any help, as it is annoying as you know what to have to listen to that A/C blower on max all day!

BTW, I have an 06 F350 King Ranch Dually, 6.0 4x4.

Thanks in advance!

Lenny

Do you have knobs or is your a/c digital?

The King Ranch comes with the digital climate control system.

had that happen to my 06.... stuck on low ....took the 65$ gamble over fords 500$ or so answer..... replaced the blower motor module .... or what ever they call it..... its stuck half way in your blower compartment .... passenger side ...behind the port where you would add coolant ...low side....cant miss it

I had the same problem in my truck (also an 06 350...)

Took it in to the dealer, they dealt with it pretty quickly.
