5 hours labor to diagnose !!! Wow!
I just replaced my blower motor assembly. I'm a below average DIY'er and it took me approx 45 min to remove all the parts to expose the blower, 15 minutes to remove the blower and about an hour to put everything back. I took an additional 30 min to clean out the blower compartment, damper and coils before installing the new blower.

I paid roughly $240 for a new blower.

If you are thinking about DIY'ing it, do a search on the site. I know there are several threads that give tips.

In general, perform the job when you are calm, unstressed and able to work without distraction. It's not hard. There are just a bunch of trim parts, tiny screws, etc...
