A/C Heater fan won't shut off!!

[Ottorot8]

Hey hoping someone has some info on this problem, the heater-a/c blower fan is stuck on blast, wont shut off, can't turn it down. Heat and a/c seem to be working fine. Any help would be appreciate thanks.

I belive that has the digital heater control? try unplugging the battery for about 10min to see if that resets it.

do you have manual or auto temp control?

it is an automatic digital control. My friend (a mechanic) told me to try a capacitor discharge, where you unplug the battery terminals and connect them together. Has any ever tried this??

Ottorot8,
My 2006 Limited started the same problem TODAY!

My heater type, shows dual digital temp display(s) with with the rocker type speed control switch on the console itself along with the +/- rocker on the steering wheel. No matter where each of these are, the fan / blower stays on high.

I did pull the #56 relay from the fuse box and the fan stops....obviously this is supposed to stop the power to the fan. But, could the relay itself be bad?

This happened on my '06. It's the Blower Motor Resistor which is located behind the glovebox. One of the bolts to remove is kinda hard to reach but it's still only a 10 min job. Part was about $60 and the dealer had it in stock as they are a common item to wear out.
