| Hey guys, so I did it, I've successfully added a filter into the system. Now unfortunately it wasnt the way I had originally wanted to, but this works for me. originally I had wanted to add the filter to the system so that the air is filtered before it ever enters the cabin, i wanted to install it in the same chase the wiper motor is mounted, just behind the battery so that every time you needed to service the filter al you had to do was remove that trim piece behind the battery and service the filter. but to do this i would need lots of modding to the body of the car itself, which isnt a big deal to me other then the fact i dont own a welder, have never welded a day in my life and i was looking for a quicker fix seeing how my efforts are mainly on my tt swap right now. i spent a few minutes looking up what kind of inline filters other cars used and what i found was quite basic, some vehicles use nothing more then an AC style filter which looks like this:
 I spent a few minutes looking over the parts and where i could add a filter so that its pre intake fan, and easily assessable for service i came up with this. to service all you have to do is remove your glove box and the filter is right there. the way i made this i wanted to be able to clean out any debre from inside the housing before i remove the filter, this will prevent any seeds or loose debre that makes it into the vent system from getting past the filter. I cut out the plastic grid from the face of the blower housing. now, when i turn on my vent and select the recirculate button, the blower housing will open the doors and give me access to vacuum out any of that crap before i remove the filter. so once this is done you just pull the old filter and replace with a new one. here lets get started. first things first we need to open up the blower motor housing.

now that you have all of these clips removed from the outside of the housing, you can now crack it open freely.

[img][ http://i202.photobucket.com/albums/aa24/preprodigy/IMG_2345.jpg ][/img]
now with the two halves separated, take the lower half and flip it upside down so that you have access to the screws that hold the motor to the housing and remove the 3 phillips screws along with disconnecting the hose that attached to bottom of motor, this just pulls right off.
[img][ http://i202.photobucket.com/albums/aa24/preprodigy/IMG_2348.jpg ][/img] once your done with that step go ahead and lift the motor straight up and out of the housing.
[img][ http://i202.photobucket.com/albums/aa24/preprodigy/IMG_2351.jpg ][/img] Disassemble the motor for cleaning, and if your fan is anything like mine, re-impregnating the bronze bearings because after 20+ years of use mine were bone dry and just recently starting squeaking. take an 8mm socket and remove the nut holding down the fan blade (this is a normal nut with right handed threads, meaning left loose, right tight) this is because the shaft has a flat spot which prevents the fan from rotating and possibly loosening the nut during use.
[img][ http://i202.photobucket.com/albums/aa24/preprodigy/IMG_2358.jpg ][/img] once the nut is removed you will need to hold the motor up by the fan blade and use a small hammer to tap lightly on the center shaft, i had to tap a little harder then gentle, but i didnt need to smash the shit either.
[img][ http://i202.photobucket.com/albums/aa24/preprodigy/IMG_2362.jpg ][/img] use just enough force to get to the point where the top of the shaft is flush with the top of the fan.
[img][ http://i202.photobucket.com/albums/aa24/preprodigy/IMG_2364.jpg ][/img] then using a pair of 45 deg needle nose and a small pry bar, i applied even pressure to the underside of the fan blade to pop it up and off the shaft. (be sure to make sure you are applying pressure to the underside of fan and NOT on the little fan teeth that run along the bottom of the fan blade as im sure these would break off easily.

[img][ http://i202.photobucket.com/albums/aa24/preprodigy/IMG_2372.jpg ][/img] ok once the fan blade is removed from the motor, you are going to flip the motor over and begin dissembling it.
[img][ http://i202.photobucket.com/albums/aa24/preprodigy/IMG_2352.jpg?t=1338004997 ][/img] you need to start by peeling the cover off the back of motor, starting on the side that the black flex hose connected to, slowly pull edge of cover up and over black hose connector.
[img][ http://i202.photobucket.com/albums/aa24/preprodigy/IMG_2353.jpg ][/img] once you have that one corner up the whole cover pops rite over and off the electrical connector side.
[img][ http://i202.photobucket.com/albums/aa24/preprodigy/IMG_2354.jpg ][/img] next remove the two small phillips screws and Slowly remove the rear cover.
[img][ http://i202.photobucket.com/albums/aa24/preprodigy/IMG_2355.jpg?t=1338005154 ][/img] once lid is removed youll see the inner workings. next carefully lift the white plastic connector up and out of its slot in the metal housing, this will allow you to next remove the brown plastic piece which houses the brushes that make the motor spin. be careful when removing this part as the brushes are spring loaded to keep them flush against the fans coils. dont worry if they pop out, its bound to happen and they are physically attached to the brown plastic and the white plastic harness clip via wire so dont be afraid youll lose them, you wont.

[img][ http://i202.photobucket.com/albums/aa24/preprodigy/IMG_2385.jpg ][/img] now that the brushes are out of the way it is time to remove the shaft/coil from the housing. remember there are two large magnet attached to the inner side of the fan housing, these wont move however, they will fight you while you remove the shaft/coil. so Be patient and go slow, you dont want to damage your coil or your magnets while taking them apart. you will need a steady and FIRM hand for this.

[img][ http://i202.photobucket.com/albums/aa24/preprodigy/IMG_2387.jpg ][/img] (side note, before you remove the shaft/coil, be sure to tak off the small silver washer from the front of the shaft, it sat under the fan blade and keeps the fan blade centered on the shaft when you tighten the nut. set this to the side with the nut you removed in the begining and be sure not to loose it. [img][ http://i202.photobucket.com/albums/aa24/preprodigy/IMG_2388.jpg ][/img] now that the fan motor is completely taken apart you should clean all parts, then take some painters tape and cover the vent holes on the outside of the motor housing (underneath where the fan blade attached to the shaft), this will help hold in the oil while you re-impregnate the bronze bushings.

[img][ http://i202.photobucket.com/albums/aa24/preprodigy/IMG_2409.jpg ][/img] this is what i used for this process:
[img][ http://i202.photobucket.com/albums/aa24/preprodigy/IMG_2416.jpg ][/img] you can just fill the hole at the bottom of the cover with oil and let it sit but for the top half i took a dixie cup, cut off the bottom and used it as a dish to hold th oil for the top half of fan motor housing.
(re impregnating bearings will take a few days, quicker if you heat the oil and bushings up, i just used my heat gun to warm oil and bushings for a few secs every couple of hours) if you dont have a heat gun just let the bushings soak in oil for a week.
