Rear Cab Vents Leaking

[kite2012]

I was wondering if any one has every replaced the rear cab vents/valves? Mine are shot and leaking water. There is standing water inside the tubes/ducts behind the back seat of my truck and getting water onto my carpet. I am hoping I will not have to remove the bed in order to do this.... Also, I am trying to find the exact name of them so I can order replacements for them. I've heard of people blocking them off but I don't want to lose their functionality.
