There were 2 options for the rear control units, 1 was AC only, 1 was heat and AC. If your controls above the second seat only have 1 knob, it's AC only, the heat/AC version has 3 knobs. The correct Answer: 1996 - 2000 (Old Body Style) Tahoes and Yukons only got the rear air option. Suburbans and Yukon XL's get the Heat and AC option.

When the heat is on why would the back vents of a 2004 dodge durango blow cold air and the front blow hot?
The control for the heat on the dash has a control for the back seat and also has a setting that says something like "Rear Control". This allows the passengers in the back seat to control their heat independently via a temperature control in the back seat (on the back of the center console). So you could have the heat on in the front and the rear on "rear control" and if the passenger in the back has set their control to cold, it wold blow cold air in the back even though you have the heat on in the front.

Why would my rear ac work but not my front ac on a 1999 Tahoe?
There is a secondary condensor in the rear of the vehicle that works off of the primary. If the AC in the rear is working and not the front, it could possibly be the air handler or the blower up front. Does the front blow air? If so is it ambient, hot, or a little cool? Incorrect: The 1999 Tahoe DOES NOT have a secondary condensor the only thing it may have in the rear is a heater core IF it is supplied with rear heat, if you are getting cold air in back and not the front usually means you are low on freon.
