Have you checked cabin air filter?
Definitely first place to start with these symptoms, though access isnt great to it.
A cloggy filter down there shows up with a variety of symptoms, often very bizarre ones... including the ones you describe. Eliminate that first before anything else.
Its often just the filter....though if previous owner ran blower long and hard to compensate it could have some extra wear too...
if running with a new air filter (or just test without any filter) doesnt resolve issue, then next steps are the blower motor or the blower motor regulator...
