Rear Heat

[Firestop52]

Any ideas on why I have no heat in the back (2006 tahoe) fan works but no heat. Thanks for any help.

I have a 2001 Tahoe with no heat in the rear vents. I have heard different things from different people. A friend of mine has a Ford Expedition with Rear vents and heat comes out.

My Tahoe just feels like the AC is on and no matter how long I have it on, it doesn't get warmer. Some people say that the rear vents are for AC only.

I realized on my 01 Tahoe, it takes a while for the heat to get to the back, but it does eventually blow hot air. Maybe a minute or two? Got a FSM on CD coming soon so I will be looking at the system and its components to get a better understanding on how it operates.

I have the same issue intermittantly, most of the time the heat works, but occassionally it only blows cold air. No idea why really...
