Front Blower Fan Issue

Front Blower Fan Issue
I encountered a weird problem with my fan yesterday on my way home from work. I usually have it set to automatic and about 68 degrees. I noticed that it wasn't blowing so I increased the fan speed manually and nothing happened. I kept increasing it until it was set to max and the fan cut on and was blowing full blast. I tried to decrease the fan speed but it wouldn't respond, I even tried turning the unit off with no effect. I pulled into a gas station and turned the engine off completely but the fan kept blowing. Finally I got home and pulled the fuse to the blower and the fan finally stopped. I fiddled with it for a little bit with no luck so I disconnected the battery and let the car sit overnight. When I got home today I tried it again with the same results. Now the suburban is sitting in my driveway with the battery disconnected.
(Both the front and rear controls are automatic)
Does anyone have any suggestions???
It's a 2005 Suburban LT.
Thanks!!!

RE: Front Blower Fan Issue
Sounds like a bad blower motor control processor. Which is basically just a solid state blower motor resistor that changes fan speeds depending on what the hvac controls commands it to do.
The control processor is located under the passenger side of the dash and is screwed up near the blower motor

RE: Front Blower Fan Issue
I installed the part on Thursday. I ended up purchasing it from my local Chevy dealership for about $120 after tax. I could have ordered it for a little less but probably wouldn't have gotten it before memorial day weekend. I did notice that RockAuto (or something like that) sells a different item that supposidly replaces this one. I figure if this goes out again I'll give it a try.
Thanks for your help!
