there is a servo near the flap (may have moved for later models) which is basically a switch controlling vacuum to and from the arm that opens and closes the recirc flap - with hood open locate servo remove and suck on the tube connected to servo - you should see the flap close. if not then your problem lies there. if it works then your servo isn't getting juice or the vacuum is weak or absent further up the line - possibly in the white canister
do all other flaps open/close as per normal?
do you find you get more air through the center vent when you are driving at high speed or accelerating? sure sign of a weak vacuum somewhere in the system
