I've removed and reinstalled the blower motor on my car about 10 times in the past few days (for a separate project). I've done it the wrong way many times (as is obvious by the many scratches on the plastic pieces), but I think I've developed a fairly foolproof method now. None of the resources I found online were suitable, so figured I would document. Don't get me wrong, this job still absolutely sucks, but it's a bit less sucky this way.
This post will cover the actual blower motor-related steps in detail, but I'll just assume you know how to do all the other work.
Also, you'll see that I have more stuff removed than is necessary. This is for that aforementioned project and is definitely not needed if you're just doing the blower motor. There's also an aluminum piece stuck in there above the blower motor. Again, separate project, just ignore it.
Prerequisites:
The following things need to be removed in the engine bay.
This plastic bracket also has to be moved out of the way:
There's three 10mm nuts under the cylinder 6 throttle body holding it in:
It also has a tab that holds the injector loom. Separate the two (and don't forget to reattach when putting back together!).
Lastly, the windshield wipers need to be pointing vertically:
Do not try to move them by hand. Turn the ignition on, pull the wiper stalk and turn the ignition back off halfway through the wiper's motion.
At this point, your engine bay should look something like this:
Time to actually get the blower motor replaced.
Blower Motor Removal:
Step 1: Remove the top T20 screw on the blower motor front cover.
Step 2: Undo the two clips at the bottom of the cover and push both of them to the side.
Step 3: Pull the bottom of the cover out past the firewall. It'll want to catch on the clips and the firewall, but it does clear with a bit of bending. Moving the engine harness out of the way also helps with clearance.
Step 4: Keep rotating the cover and pull it out on the intake side.
Step 5: Remove the top T20 screw for the right side flap assembly.
Step 6: Remove the other two T20 screws holding the right flap assembly in.
Step 7: Pull up the flap lock.
Step 8: Pull the flap assembly forwards and up so that it just clears the firewall. Don't pull more than that or you'll risk breaking it.
Step 9: Wiggle/rotate the assembly until the top part is fully out into the engine bay.
Step 10: Wiggle/rotate again until it looks like this and pull it out.
Step 11: Unplug the blower motor.
Step 12: Unhook the blower motor retainer.
Step 13: Pull the blower motor forward out of its bracket.
Step 14: Carefully pull the blower motor out through the exhaust side. Be careful not to damage the vanes with the front cover clips.
Blower Motor Install:
Just follow the removal steps in reverse
Make sure the new blower motor is oriented the same way as the old one and don't forget to reattach the injector loom to the bracket in the back of the engine.
Only other thing worth noting is to make sure that everything lines up on the left side when reinstalling the right flap assembly:
