Question about 2001 Dodge Durango

1 Answer

I need to know if my 2001 Dodge Durango has vacuum hoses for the a/c vent doors or if it has actuator motors that control the vent doors. I can't get the climate control switch to switch the vents from the front vents to the floor vents or the defrost vents. The fan control switches for front and rear have an audible click, but the directional switch for the front doesn't click when it is moved. So could it be the switch, vaccum or actuator motors?

The are vacuum operated via vacuum motors. Check the vacuum reservoir under the hood first if you have no vacuum.

SOURCE: There is no air flow

You need part GM Part number 89018675 or ACDelco 15-73596. The Mode Selector Actuator. What happens is the part is a CHEAP part POORLY designed and when it goes to turn the flaps inside the HVAC unit its the plastic gear slips instead of turning the flap!!!

Just to forward you you might want a deal to install this art for you unless your good at fixing your own vehicle, because you need SMALL sockets and a lot of patience to get this part in!!!

The part is ALMOST directly above the steering shaft for your steering wheel, so theres a lot you got to remove before you will even see them!!!

I only recommend you to have a dealer put this part in for you, unless you have your own service manual!!

Because there is 5 of these darn things and if you pick the wrong one you will have to do it all over again!!!

3 on the Drivers side and 2 on the Passengers side!!

But replacing this part SHOULD solve all your problems!! AS it did for me and i was having the same issues as you have described!!

SOURCE: climate control system only blow air out defrost vent

there is a good chance that you blend air door is stuck closed over your heater core and therefore not allowing the heat to flow, also your door that opens and close your direction of flow from the floor ,das,vent and defrost.your going to have to remove the lower cowling of the dash on the passenger side analso some of the center dash to actually check to see if the cable,servo motors. are acuating the doors.the issue could be just a stuck door or a misaligned cable or that it came off. that falls under the mechanical side of probabilities. electrical would most likely be a faulty selector switch or a servo motor

SOURCE: 1986 Mercedes 300e The air conditioner vents blow

All the blend doors and vents are controlled by vauum. If you look in the rear firewall behind the brake master cylinder you will see a vacuum check valve with lines entering the cabin of the vehicle. The yellow colored ones are for your central locking,the green for a/c system, and red for your heater/water valve,clear for your source. Try isolating your vac. systems by unplugging lines and capping them off. Any leak in either system can adversly affect another system. So isolate your leak and then you will have to test your actuaters in the leaky system. If you unplug the red line and cap it off-the water will stop entering your heater core.

I need instructions and diagrams to replace or repair 1993 Dodge Shadow HVAC vacuum actuator motor and or mode door actuator.

You shouldn't have to pull the heater core. The older dodges were very popular for leaking out of the switch assembly itself in the dash. Have you checked under the hood for vacuum leaks?

1998 Dodge Stratus - Air conditioning is blowing through the defrost vents

Vacuum controls this circuit and leaks will cause blend air door to default to defrost. Check for bad check valve or hose leaks under hood first as these are the easy ones to get at and under hood heat causes deterioration.

1997 dodge Ac not blowing through front vents

Depending on what system is in that truck you may have a bad blend door motor or a vacuum leak, check around the engine for ant vacuum leaks or dissconnected lines, if its controled by selector motor then motor may be bad, this motor move the door to contorl which way the air comes out ,like defrost or vent or floor, the actuator motor is located under the dash bolted to heaterbox, this may be hard for you to find as there are 3 ,actuator motors, they control the recirculation door then one for temp and last the selector actuator. the best way to locate bad is to locate one at a time and watch as you move all heat controls until you find the one that doesnt move, that will be the bad one. hope this helps.

Cold air on passenger side warm air on drivers side

Actuator motors either get a tear in the rubber or a hose is broken and not letting vacuum assist in its opening.
You can try moving the lever by hand and see if the air gets colder on the bad side.c976077.jpg

Vents for heater wont change all the way....air blows from top,middle and floor...

sounds like you have an issue with the vacuum going to the blend door actuator. Check for possible leaks and or a defective vacuum actuator switch, but most likely a vacuum leak issue.

My durango does not heat up fast enough

Ok then the problem is the air temp control blend door actuator inside the dash. This is a very common complaint on all models since they went to an electric motor operated blend door from the old vacuum motor design.
