hello, just wanted to check my cabin filter on my 04 es 330, did a google search found out how to get at it, pulled the glove box, blew it out with an air hose, had some leaves and junk in it, seemed dry, this wasn't that hard, but the little shock or what ever you want to call it, fell off. i can see where it goes, but can't get it on, not now, try later. glove box lines up o.k., just opens fast. i don't use it, only thing in there is the manual. how often should you change this filter? not going to the dealer for this, i just won't use the glove box. ran the air and heat, everything works fine. car has 61000 miles. runs and drives great. also, how cold temp. F. should the air be coming out of the vents on cold settings? thanks
