Clicking noise from air conditioning fan on 2004 Infiniti QX56

I hear a clicking noise possibly coming from the a/c fan (blower) when fan is not in use. Noise starts when I start up the suv and sometimes while driving. The a/c or heat can be off or on and it still makes this noise. HELP!

I have the same problem. When switching from heat to AC it makes clicking noise from under dash & AC doesn't work.

Sounds like the blendoor acutator getting stuck between vent levels. Problem is buried behind dash near heater core.
How did you fix this problem? Can you PLEASE help!, THANK YOU!
