Alright well this is problem I encountered I think a couple years ago, I could not find any information on the topic, so I thought how about I document it as best as I can, maybe help someone out.
So removing the blower is fairly documented on the internet that's not what I'm here for.
Just remove the blower cover under the windshield, find the blower itself, its held on by on big clip, you can unclip this with a flathead screwdriver, and don't forget which wires attach to which terminals on the blower.
Now my problem came from the fact that the used blower I bought had a few blades missing, and my own blower was dying but had perfectly fine blades.
So I looked at the blades on both blowers, didn't seem to be held on by any clips or didn't seem that they were "cooked" on the shaft I guess.
I thought what the hell let's try it. Got help from a second pair of hands. The idea we came up with was that one of us would grab the motor and the shaft with locking wrench/pliers, and the other one would grab onto the plastic blades.
First we decided to heat up the plastic blades to "expand" it a little bit without deforming it at least, and I don't have a heat gun, so we used a blow drier, and blew at it until it felt pretty hot to the touch, went around the inside around the shaft and outside the blade also around the shaft. Meantime we also applied some WD-40 to the point of connection of the shaft and the blades.
Also, I spent a fair bit of time sanding the outer part of the shaft that was sticking out of the blower with 300grit sandpaper as it was dirty, sort of to "slide" the blade out easier once it gets moving.
And remember to wrap your hands evenly on the fan blades, don't forget this is still plastic, you can break it. Wrap your hands around the outside evenly, try to extend your fingers to the base of the fan blades to apply pressure there too.
So, heat it up, trying to twist it, and it gave in.
If you're looking at the blower from the front of the car, right side is white, left side is black.
BUT! This was a very tight fit, so we couldn't just slide it off, so we just kept twisting it off the shaft. So just be careful with the plastic blades.
And there it goes.
This is a very good opportunity to lubricate the bushings for the blower shaft, on the outer edges of the motor. These failed on my old blower and caused the whining noise.
You can already guess that the install process is removal in reverse order, pretty much yes.
Just don't forget to heat up the plastic fan blades again BEFORE installing them on the new motor in the right spot, lubricate and sand the shaft as well to ease the installation.
And install it on the car, attach wires, clip the blower in. Try it on.
The wires pretty much have become molded to their place after all these years, so you can't really mess it up, unless you got new wires.
But still pretty easy, there's a male and a female, get them together.
Don't forget to clip the motor in.
You're done.
