Why does a Suburban blow cold air in the rear and hot air in the front?

There are separate expansion valves in the rear, so even if the front system is failing, the rear unit could still work normally.

Why does the front ac in your 1990 suburban blow cold but the back blows hot?
It is possible that the rear A/C lines have been cut and sealed so the freon stays in the front but does not go to the rear A/C. That is the case on my SububanAnswerThe suburban may have a heater core in the rear blower that is not shutting off. AC cannot blow hot, there is a coil for the AC and a separate coil for the heater. A simple fix is to have a shut off valve fitted under the hood to turn off the hot line to the front and rear blowers.

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.
