Question about 2005 Dodge Grand Caravan

1 Answer

Cabin heat control is out

I beleive there is something wrong with the heater motor, or it could possiblly be the control hub. The heat blows in the rear cabin however there is no control when trying to switch the heat in the front and no control through the switch for changing how much the heat blows. The only time the heat comes out of the front is if you are driving highway speeds. Could this be the motor it self, or a problem with the switchboard, or is there a flap that could be getting stuck somewhere?

Try hitting the blower motor with a hammer handle and see if it starts, if it does replace it.

I would have to say the resistor also. Cheap part and the labor is free when you do it yourself. It should be located behind your glovebox.

SOURCE: Rear heat not blowing on 05 grand Caravan

If you have the heater control up front on the floor or on defrost you should check that the heat is not blowing from under the d/p seats. If you move the heater control to dash you should have it coming out the top vents.

You could be having a coolant problem and need to check that first, If coolant level is normal you might have a thermostat going out. Both will cause your heat not to warm up at normal speed. If you need any thing let me know.

There is a vacuum leak under the hood. Find the vacuum line on the passenger side where it comes through the firewall and follow it to the engine. You system needs vacuum to operate and without it the default setting is on defrost for safety reasons.

Your blower resistor may be wearing out or corrosion setting in. The part is cheap and you can probably replace it. This link shows where an 01 is located. Yours may be in the same spot on on the engine bay side of the passenger firewall. Check with your auto parts store also for location.

My 2002 saturn sl1 is weakly blowing luke warm air out when i have my heat at its hottest setting and my fan at full blast.


the best way to find out if the problem is in the cabin or under the hood is to touch the heater hoses when the motor is at operating temperature. turn on the heat full blast and feel the hoses; if they are both almost too hot to touch then the problem is with your blend door or its control mechanism. if one is noticeably cooler than the other then you,ve got a clogged heater core. if they are both cool enough to touch then your motor is running too cool

The heater kicks on but only blows cold air


Air Temperature Control Blend Door Failure No Heat or no AC (dependes on where door sticks)

In all modern cars there is a tiny DC electric motor driven gear drive that moves a plastic door that blends heated and cooled air from the AC and the heater core, this is called (interestedly enough) the air temperature control blend door actuator. The motor that moves this door fails because the door starts sticking from warping, most common complaint is no heat but it can be no AC as well. To replace these parts (blend door and blend door actuator) you must remove the entire dash from the car. Always have this problem confirmed by a dealer or qualified repair shop as it is a very expensive repair.

Other causes of no heat in the cabin are engine thermostats that are stuck open (engine runs cold) or air bubbles in the cooling system.

Heater blows cold air for 20min then blows hot


There are a few things that can cause this problem. Reason #1 a low coolant level can cause the heater core to receive less coolant flow hence causing the heat to come less quickly. reason #2 sticky heater control valve, if this control valve is stuck closed coolant cant enter the heater core hense wont heat up the cabin, reason #3 clogged heater core, over time some heater cores will clog up even sometimes start to leak in cabin. All these are normal circumstances and should be checked. Good luck

No heat in 91 Cadillac Sedan Deville


I would beleive more that you have build up in the heater core. Try taking loose the heater hoses from the block and use a water hose to spray into one of the hoses letting it come out the other hose then switch hoses with the water hose and keep reverseing for 2/3 times each hose. sounds like stop leak may have been used in a prior time and may be blocking water flow.

Good luck,
