Reach in and remove the bracket that holds the O2 connector and fuel line clip. It comes off with 2 13mm nuts. The blower motor is then very accessible. I think it has about 6 7mm bolts holding it in and then the one connector. Wiggle and turn it to get it out..

Your instructions make the process seem very simple and I am sure it is.

Are there any pics out there just to give me an idea of what I am working with?

Do I need to make sure not to disconnect certain wires or hoses, is there a risk of shorting out something?

Thx

Oh..I forgot..remove the strut bar..4 13mm nuts.

Unless you touch the power connector on the back of the alternator..there'* nothing nearby to worry about if the car isn't running.

I would have taken pictures when I did mine..but it was done before the first picture happened.

Do NOT move the car or jack it up with the strut bar off the car. You can upset your alignment.

The blower motor change is no more difficult than changing a battery.

Did a search for "blower motor" Found this under a thread titled: "blower motor replacement":

Check for bad motor by unplugging connector on motor and setting controls for high speed fan
connect test light across terminals to see if power is getting to the motor
if power is getting to motor, and motor is not working properly (e.g., requires whacking to get it to work), its almost certainly bad. so....

remove strut brace (13 mm x 4 nuts or bolts)
remove engine cover (remove oil fill tube front and unsnap rear)
unclip O2 sensor connector and fuel lines connector from rear bracket (needlenose pliers)
remove rear bracket from rear cylinder head (13 mm x 2 nuts)
remove rubber cooling tube (heat with hair dryer if cold to prevent cracking)
remove bolts attaching motor (7 mm x 5)
remove insulating cover from motor (if your car has one)
gently move fuel lines out of the way and pull motor up and out
carefully remove rubber gasket from old motor; install on new motor
remove foam gasket from electrical connector, install on new motor

reverse to install; adding dielectric grease to electical connector
enjoy hot air if winter or cold air if summer

BTW, following the factory service manual procedure to test for a bad blower motor resulted in a waste of about two hours time. Why start by backprobing the blower relay (which is pretty much inaccessible!) when you can just test for power at the motor connector?

The only caveat that I would have is when you're done, to check the vacuum fitting that goes into the firewall next to the master cylinder booster. If you're sort of clumsy, like me...you may end up knocking that loose.
