Hi,
There have been reported issues with a blower motor that won't turn or some that won't turn off. There is an internal fault in the blower motor control module. Take a look through the first three pics below for the bulletin and let me know if you feel this mirrors what you experience.
The remaining pics are the diagnostics for the module.
If you haven't already, you may want to consider having the can-bus scanned to see if there are codes stored in this module. CAN stands for controller area network. Basically, all the modules are tied together via a few wires. This type of scan will retrieve codes regardless of the module storing them. Here is a link showing how it's done.

Let me know your thoughts and if you have other questions.
Take care,
Joe
