'98 Mitsubishi Galant


I have a '98 Mitsubishi Galant, yesterday when I started it up it started making a clicking sound, today i found out if I set it to recirculate air the sound goes away. The clicking slows down when there is higher draw on the battery. Any ideas what making this noise, and how to stop it?

Probably a foreign object has fallen into the air ducts and is touching the blower fan. NEVER put any objects on the dashboard as they tend to drop into the defrost ducts and work their way to the blower.

I've never had anything up on the dash. Is there usually a separate fan for fresh air intake and one for just circulating air?

Just one fan, the blend of air is done with moving a door. Pull the blower motor and see what is in there.

What happens if you turn the ac/blower fan off... Does the clicking go away?

No, the clicking only goes away if its recirculating air.

The clicking isn't affected by fan speed or which vents it comes out, and only clicks with fresh air.

So if its on fresh air but the fan is off it still clicks? Does it change by engine RPM or vehicle speed? What about if the key is on but the engine isnt running?
