I have a 2004 4runner. the rear window won't roll all the way down because its full of dirt and dust. Is there a guide or instructions on how to take the rear door apart to clean it??

I'd suggest a shop vac, but will not get down in there...could use a garden hose set to blast on a warm summer day, then leave it co air can dry it out, or get a mechanics air-blaster and with air try to dislodge the crud...realistically disassemble, then shop vac, then put it back together~

phillips screws and "chrismas tree" fasteners that if you're lucky will stay with the hardboard, not stick into the steel, but there should be some phillips screws then use a long knife to separate between the hardboard and steel, christmas trees will pop out, work your way around until you can free the hardboard, then goto town with your vacuum and clean it up, replace the weatherstrip to try to keep crap out of there~
