Hey fellas, long time reader, first time poster.

I have a problem with my auto climate control system on my 2000 SE. Within the past 2 days something happenned such that when I change the "mode", meaning the port for air flow (foot, face, defroster, or some combination), I hear the system doing something, but all of the air is coming out through the foot area.

I'm baffled and really ticked off because I know if I take it to the dealer, I'm going to get screwed over. Do you think it could be the filter that is clogged? I hear it doing something and when I hit defroster, there is a teeny little air I detect from the defroster, but everything is channelling through the feet area.

Anyone? guidance? help!
Thanks.
