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.
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.
If you have rear heat as well, you might also check to see if the heater hoses are turned off. I had this problem a number of years ago -- AC wouldn't cool right in the summer because the hearter hoses to the rear were still turned on. (Conversion shop job) CiP
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.
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.
The heat is transfered from the front vents and does not work when the defrost mode is on. www.trailvoy.com
No. In fact, the wires from the rear if connected to the front will fix a 250 problem!
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?
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.
It's the flat, flanged cover on the front (and sometimes the rear) of a shell & tube heat exchanger.
No, not feasibly. Front wheel drive cars typically have a transverse engine (as opposed to a longitudinal engine found in rear wheel drive cars) and a transmission with a different output location that that found on a rear wheel drive car... I won't say such a conversion is impossible, but it's highly impractical.
The problem is that the rear heat/ac vent that mixes the two to control the climate is broken, I had it replaced at the dealership since it kept knocking when I tried to operate the rear climate controls.

My 2003 Sienna has one tank that is for the front and rear window. You might have a problem with your pump or something else. Does your front wiper work?
