Question about 2001 Dodge Ram 1500 Truck 2WD

1 Answer

Blend door not working.

My blend door is not working. I get no air to the front vents and the air is diverted to the defroster. Air will switch to floor. This was an intermediate problem but is now pretty much stuck. How is the blend door actuated. How difficult is the blend to access to repair? I have a similar issue - though the vent air is diverted to the defroster vents when the accelerator is depressed (for instance, going uphill). The air returns to the front vents when the engine is not taxed (on a flat surface, decellerating). Any ideas?

    Yes, my mechanic agrees with your diagnosis, but so far is unable to locate the leak. Thanks for your input!

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.

Air conditioner switch is stuck in defrost position what to do


Problem is usually a stuck or faulty blend door motor under the dash.
The blend doors direct air thru the heater and ac evaporator as well as the vents.

Most of A/C air is coming out of defrosting vent. Could there be a switch malfunct.


Do an internet search for "blend door repair" - - - the blend doors direct air thru the heater core and evaporator core along with the vents.

Cold air comes out the defrost vent all the time. 1994 buick le sabre. no air comes out the front registers.


The most common cause is the blend door actuator. It's the door that diverts air between the floor, vents, and defroster. Sometimes the part will get stuck in 1 position. Some cars have cable driven blend doors, others are electronic.

95 chev. pickup. Cool air comes out at floor. Cannot divert any air to the vents or defroster vent. Can feel warmth on the black plastic box like thing near the floorboard so I know there is warm water...


It sounds like the actuator that diverts the air may have gone out. I would suggest replacing the blend-door actuator so that your air will go to the right places. The blend door actuator shouldn't cost more than $150.

A/C only blows through defrost vents. Won't switch to floor Or foot vents . Have tried a 2nd control unit in dash


It sounds like the blend door actuator which diverts air from defrost to vent to the floor.
The bad news is it's a bear to get at. It's located behind the glove box.

Air blend doors do not work. Air blows from defroster vents


check or loss of vacuum to mode control switch in dash ac control. these are not blend doors, they are air flow control, a blend door controls the air temperature not where it comes out.

Blend door not working.


The bleed door controls air temp not where it comes out, dash, floor, defroster, this is most likely a mode control switch problem, that switch is on the ac control head.
