Your blower motor is mounted under the hood near the passenger side.
And it is very easy to remove.
Here is a video of a girl replacing the blower motor .
If you have to replace the blower motor and it comes with a gasket like the girls aftermarket blower motor that was not installed at the factory, take the time to remove the fan install the gasket then reinstall the fan once the gasket is stuck in place properly to prevent air leaks.
I am guessing you may have felt the box that contains the heater core, but it is hard to tell by your description.
If you want to know for sure what was hot get some lighting and take video or picture of the part that is hot and we can confirm if it is nothing to worry about.
