Last night I got that periodic sound that sounded mechanical. Turns out it was from the blower fan. Yes there are three Phillip screws you have to remove. One is located next to the sloping bulkhead where you can't come at it from 90 degrees, more like 70 degrees. Because of that I had to use a straight slot for that screw. You have to peal back your carpet to do this. Once you get all three screws out, you will only be able to move the fan down two inches because it will begin to hit the sloping bulkhead. There is a sheet of what looks like sound-proofing that covers that bulkhead. The only way I could get the fan out was to remove around three inches of that soundproofing so that the fan blades clear. It is still a tight fit, but you can't get it out any other way that I could see. I had a leaf caught in the fins that made a sound as it went around.well I tackle-ed this blower motor.. Good news and bad.. but here are some pic I hope helps the next person Good News it wasn't my blower.. bad news I had a hard time getting it out.. which I'm glad I didnt have to. I got it all loose and few inches downt then the floor stopped me..and clearance was an issue..so I taped it up against the mount and whata know.. no more whirlie bird sound. if pict dont show here are the steps
1st I lowered the glove box... there's elstic string on the side that helps hold it, push in the sides of the box to release the locks and then disconnect that string..
2 there will be a bolt on ea side of metal bracket 10mm remove them. then it just slips out of its grove from ea side.
3 remove phillip screw for wiring hardness and plug to motor move them out the way
4 remove the 3 screws holding the blower in place the far back screw probably needs a very very short 90degree phillips based on the steep incline of the floor. This back one caused me a lot more time.
5 here is the tricky part getting it out.. I almost cut into the padding. which was soo far up under there it seem like the only option.. good luck I hope some else can figure the rest out to get it out.
I have several pict I couldnt get them to upload
