Because the rear heat and front hear are 2 different systems. If for example the front heater coil has broken the rear one may still be functioning.
Front heater core could be plugged up. Try flushing it out.

Why does your rear air only work sometimes in your 1994 ford econoline conversion van?
You rear heat will only work if your front heat is on heat and feet. If it is on vent at the front of the van it will not heat the rear of the van. Not sure why but that is how ford designed it.
What is the problem when a conversion van has front heat and no rear heat.?
Check the valve that lets the heated coolant circulate to the rear heater core. You will not have any rear heat without the fluid circulating.
Why does the rear heat on a 2004 ext trailblazer work only half the time And is this heat from the engine or is it heat coil in the rear?
The heat is transfered from the front vents and does not work when the defrost mode is on. www.trailvoy.com
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.
Where is the problem in the heating system when rear heat works but front heat does not?
I would first check either the controls to the front heater core or a blocked front heater core. It could also be a blocked or missing heater hose to the front heater core, although that seems quite unlikley.
How do you recharge the rear AC in a 2001 GMC Yukon?

How do you know which heater core you need to replace on a 94 ford aerostar front or rear you have heat but no defrost and stream comes out of the vents when heat is on?
Front heater core is in the dash, the rear heater core is all the way in the back of the vehicle. If you have steam coming out of the dash vents, the front HC is leaking. If you have steam coming out of the rear heater vents, then the rear core is leaking.
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.
Why would a 1999 Windstar LX just blow cold air from the rear heater?
If you have your system on heat and you are only getting hot air from the front vents and not the rear you might have a bad actuator motor. There are two different plenum doors on your vehicle. One opens and closes for heat to the front passenger area. The other one opens and closes for the rear passenger area. There's another answer out there for this rear A/C problem advising owners that the rear control knob on the front dash is bad and replacement is 'a snap'... Can anyone comment on these two trouble-shooting tips?
Where is the dollar plate on a heat exchanger?
It's the flat, flanged cover on the front (and sometimes the rear) of a shell & tube heat exchanger.
