You know, I've heard this a lot, and granted it's not a simple job, but it's
not nearly as hard as some would have you believe. The first one I did took
me around 5 hours from start to finish, and that included having to figure
out a way to get the rusted nut off the motor shaft. I've got it down to
less than 4 hours now and that's without taking the shortcut of cutting
holes in the blower housing. It's one heck of a lot easier than replacing
the sagging headliner in a 700 sedan, I speak from experience. You just have
to pull the dash out (about a dozen screws), pull the console panel out (4
screws and 2 clips), pull the side panels which will now be loose, remove
the 4 screws and pull the frame off from the center console, then you can
take out the screws and clips to get the side panels off the blower housing
and get into the motor. It looks scary but take it one step at a time and
put the screws in labelled bags and it should go pretty smoothly.
