Heater Fan wont turn off

[mrwall]

I have a 2005 Limited model, all of the sudden the heater fan started blowing on high speed. it will not sut off with the control button, or when i shut the system off. it does it with A/C and Heat... any ideas?
thanks!

I would try a new switch check what parts are available. If the power is not shutting off.
