Thumping rythmic noise from passenger side dash
Don't you just love it: thump, thump, thump, thump, pause, thump, thump...? I've found the best solution is to use compressed air as used in cleaning the keyboard of your laptop. Take a very thin (but strong) metal strip about 1/32" thick and gently place inside the edge of the recirculate button. VERY GENTLY depress the recirculate button just until the thumping stops. Apply just enough upwards pressure on the strip to hold the button in place. This creates enough of a gap for the air to blow behind the button. hold the can of air no more than one inch (1") away from the strip and aim directly to the left or right of the strip. Once you've cleaned from behind the button completely, that mother thumping (LOL) song will be no more.
