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 would be the reason your rear heat wouldn't work in your 1998 Pontiac Montana but the front does work back makes noise but no heat produced or even air Fuses have been replaced?

usally there is a valve. Should be in the collant line that goes to the back heater. So when you turn on the heat it opens the valve to let the collant into the back heater and then closes when you shut off the rear heat. follow the heater lines from the back and see if there is a valve hope this helps !!!!!!!!!!!!!!

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.

There is a heater blend door actuator on the drivers side foot well, near the gas pedal. They tend to go bad and it doesn't open the door to let the heat go to the front. Looks like this. Costs about $40-$50.

Why would rear heat in van work but front heat don't get hot?

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.

When you stand in front of a campfire why does your front feel warmer than your back?

It is warmer because the fire gives off heat. Your body is not a good conductor so the heat can't travel though your body.
