Intermittent A/C Blower Failure - 2005 Prius

I've got a 2005 with almost 300,000 miles
and just recently the A/C blower has intermittently
failed to start up. However, if I give the console
a smack on the driver's side of the nav screen the unit
usually starts up.

Now, I am assuming it is the start of an electric motor failure
in the A/C Blower unit, however, the blower is apparently
located under the passenger side glove box. So I am
wondering if that is whee the blower is why does smaking the driver
side of the nav screen start up the motor?

Just wondering if anyone has had a similar experience. Its apparently
a pretty easy fix to replace the blower motor, and only about a $50 part,
but when the motor doesn't turn on, the Prius shuts down the a/c altogether
so you definitely need the motor! lol

 

Not sure. It hasn't stopped working since I wrote the post, but the next it stops I'm going to try slapping the inderside of the glovebox!
