blower motor change is easy, under passenger side dash.

remove black plastic panel

remove wiring plug

remove blower

remove regulator bolted to blower

if you move carpeting forward to make room place a towel on floor so if you drop any screws they don't fall into nether regions of floor.

before you order a new blower, remove old one along with cabin filter, clean everything, let a little trans fluid soak overnight into top of blower motor spindel, then connect back up.

I did the above about a month back, it cured a blower speed related noise I was getting.
