There is no average

You pay for the diagnostic time required to find a problem

Then you pay for the repair

Then you pay for the parts

Been that way for 60 years

No shop can tell you what the unknown will cost

We have no idea what country your in, or the currency

2010 Dodge Journey with 2 zone ATC no heat coming from passenger side but good heat on drivers side. Heater doors seem to be operating okay. Any ideas on what the problem is?


Vehicles with dual zone heating systems have two blend doors - one for each zone. These are different than the mode doors, which direct the airflow to floor, dash, defrost, etc. Apparently the blend door for the driver's side is working, but not the one for the passenger's side.

DTC B1340 Air Mix Door #1 Movement Problem !
The heater and A/C programmer supplies voltage to an internal motor that drives the air mix door. The heater and A/C programmer monitors the air mix door position feedback from a sensor on the motor. If the air mix door is requested to move but the feedback voltage does not change, the heater and A/C programmer will store DTC B1340. If the air mix door feedback indicates that the feedback is near the hot or the cold extreme, the DTC will not set. Evaluate the operation of the air mix door through self diagnostics as described in the test description.
Test Description
Perform the Diagnostic System Check before continuing with the diagnosis of this DTC.
A Scan Tool allows for the direct control of the air mix door by observing the following conditions:
• The air mix door position feedback value
• The value`s difference from the air mix door commanded position value
These readings indicate a fault internal to the heater and A/C programmer in the air mix door sensor feedback.

Did you perform the Diagnostic System Check?
--
Go to Step 2
Go to Diagnostic System Check
2
With the engine running, connect a Scan Tool .
Turn the dual zone to OFF (passenger temperature offset at 0 or OFF).
Exercise the suspect actuator using the temperature control on the control assembly.
Is the door being commanded (COM) to the proper high and low values?
COM High 100 %
COM Low 0 %
Go to Step 3
Go to Step 4

If you are unfamilier with this , i suggest you take it to a ASE certified repair shop or the dealer .

Why is it blowing warm on and off on the driver side and blowing cool on the passenger side?


Here's is a little background and a couple of thoughts. Turning to the background, first. The heater/air conditioner system in your 02 uses the same set of ducts located in the instrument panel. In turn, those ducts are linked to what can be considered miniature version of the cooling system in the engine compartment (yes, this is a greatly simplified version). The whole system, in fact, is run off the main heater/ac system, however, it has a separate series of controls so that it can function properly.

When you dial a temperature, a signal is sent to the heater/cooling system telling the system to open a series of baffles, directing a flow of heated or cooled anti-freeze/coolant to the proper "radiator" behind the face of the instrument panel. In turn, the fan system activates a series of doors behind the instrument panel so that the flow of air is directed through the "radiator" and into the passenger compartment. This is essentially the heater/cooling system work.

Now, you say that the driver's side is hot, while the passenger side is cool. What has happened is that the flow of heated coolant that is supposed to heat the passenger side of the duct system is blocked. Since there is no heat to warm the air that is flowing past the fins of the "radiator," the flowing air remains cool to cold, depending on the weather and ambient temperature. The result is that one side of the car remains cool. And, since the other side of the "radiator" is normal and the air is heated, it is warmed.

That is the most likely explanation for this.

Another possibility is that the baffles themselves are stuck and the coolant that is supposed to be directed to the passenger side is not being directed their.

Either way, your technician has some work ahead.

No lights are most likely the dimmer switch at the light switch, Replace it. rear defrost, could be a broken wire, switch is bad, or the little stands that go across the window, one is broke. No heat, probably the vent motor on the passenger side under the dash, close to the center console.

1998 GRAND CHEROKEE BLOWS ON DEFROST ALONE


Hi I have a 2002 JGC ltd and it is most likely your dampeners or louvers located behind your temp controls (inside the dash) for driver and passenger sides that control the direction of air flow from air outside in, circulation, heat to windshield, centre and or to floor etc. I had a friend that had heat only to the passenger side and cold air blowing to driver side. He took it in and they replaced stuck dampeners and it was not cheap. Sounds like the tipical problem with heaters.
