Hey, I've been poking around inside the dash recently, trying to fix a few things. I've pulled out some large chunks of foam. I'd normally try to wedge it back in, but right now I'm waiting for a part (CDL unit) so would like to wait before trying to put it all back the way it was.
I'm wondering if the foam is designed to have any structural function (e.g. holding up an air duct), or is it there mostly just for insulation (heat/cold/sound/squeaks).
P.S. A photo of the big block of foam I pulled from inside the dash on the driver's side (to change out the CDL unit) can be found here: http://www.lotustalk.com/forums/f129/door-locks-not-working-properly-72467/index3.html
