2004 Cavalier Clicking from under dash

I have a 2004 Cavalier and there is a clicking coming from under the passanger side of the dash. the only time the clicking stops is if i put the climate control on recirculate. It even clicks when fan is turned to off. I've looked around online and the only thing i find about it is the fan blower motor but i dont know how to take the cover off to even look at it.....Please help its really annoying

Suffered same problem repaired as follows

While clicking, disconnected connector with two wires under the carpet on the blower fan housing. One was green and the other was dark. This was near the fendor well. Not the main plug or the blower plug.

Result Clicking stoped but recirculate gate will not open

I have the same problem! Do you have a picture of what to disconnect? Do I need to remove the blower motor housing?

Thanks!
