Why does cold air come through the passenger floor vent when the heater is on in your 2002 dodge caravan in any heating mode?

By the heater

Disconnect the send and return lines to the heater core and connect them together

The Heater Core is located passenger side next to the firewall, inside the vehicle. The Heater Core is located passenger side next to the firewall, inside the vehicle.

It is over the passenger side strut tower, accessible from under the hood.

It sounds like the heater core is leaking. Check for the smell of antifreeze and that will confirm the bad heater core.

The heater housing is behind the dash on the passenger side.

The heater core is behind the dash the passenger side of the car.

The heater would not be working on a 1990 Dodge Grand Caravan if the heater core is damaged or blocked. Hot coolant from the engine must flow through the core to allow hot air to pass into the cabin.

it's on the outside on the passenger side.near the heater core hoses.

The heater coil is leaking. Water from the cooling system runs through the heater coil to heat the passenger compartment. Antifreeze is corrosive, some heater coils are thin.

Nicrome wire is used in a heater as a heating element.

Very hard.............. You will need to discharge the a/c system, pull back the dash and remove the complete a/c and heating box to remove the heater core.........

The heating element of an electric heater is a "resistor", the cord which conducts the electricity is not. The resistance of the element of an electric heater is very high. As current flows through the heating element, it becomes red hot and glows. On the other hand, the resistance of the cord is low. It does not become red hot when current flows through it.

my heater switch on my vauxhall frontera as just stopped working but we can feel slightly heating coming through

Sounds like your heater core has gone bad.

The gas water heater works through a principle of physics which is known as convection. The gas heater is similar to a water heater only that it has one heating unit.?æ

Direct heating means heating an object directly by a heater but indirect heating means heating an object by another object which is being heated by a heater.

The heater core is under the passenger side of the dashboard inside of the housing that holds and covers most of the A/C an Heating system components. IT is NOT easy to change.

It'll have an HVAC compartment which contains the heater core, blower fan, and AC evaporator. It'll be located (or partially located) under the dash next to the passenger door AC vent.

In line on the heater hoses on the passenger side of the engine. Has a small vacuum line to it and both heater hoses go through it. The heater hoses are smaller than the radiator hoses and go through the firwall.

A convection heater works on the principle of air convection currents circulating through its body and across its heating element. Heating element heats up the air, causing it to increase in volume and become buoyant. A convection heater can have an electrical heater element, a hot water coil, or a steam coil.

It is your car's cooling system that removes the excess heat from the engine. Then, by a convection process, transfers that heat to your heater core. The heater core in your car is similar to the radiator in the front of your car; in fact it looks like a small radiator. The difference is the heater is mounted inside the car and air is blown through the fins of the core. The heater hoses transfer engine coolant to the heater core, this allows the heat from the engine coolant to be utilized and warm the passenger compartment air. The heat transferred lowers the temperature of the liquid coolant, which is then circulated back to the engine to absorb excess heat again, a continuous system. Whereas the radiator is located at your car's front grill, the unit that transfers heat to the passenger cabin ( heater core) is located inside the dashboard. Heated liquid coolant circulates through tubes in the heater core, and a heater fan blowing across those tubes, as well as through little fins encasing the tubes, directs warmth through the heating vents into your car's passenger cabin.

heater core is a radiator-like device used in heating the cabin of a vehicle. Hot coolant from the vehicle's engine is passed through a winding tube of the core, a heat exchanger between coolant and cabin air. Fins attached to the core tubes serve to increase surface for heat transfer to air that is forced past them, by a fan, thereby heating the passenger compartment.

The Dodge Caravan heater was invented in 1984 by the Dodge and Mopar companies. Since it's creation it has evolved into a much bigger and popular van.
