Ac noise

[Anthony Lawlor]

My 02 1500 make a rumbling noise from ac vents....possible restrictions....what should I be looking for?

I would remove the blower motor and see if the recirc door has broken and is laying on top of the blower outlet.

See if you can hear the recirc actuator moving the door when you select fresh air and back to recirc.

Thanks....now I have a good place to start.
Never had a ac problem before.
