To explain or elaborate, The air will not come out of the dash vents. I had one making the clicking sound. I found out it was the upper one near the glove box. I replaced it (it was defective with broken gear teeth) but that did not solve the problem with the dash vents blowing air. I took out the actuator below the faulty on e, and it appears to be working fine. Please don't tell me it is the damn one behind the dash!
