DTC B0361, B0363, B0365, or B0367
Circuit Description
The following DTCs are for the left and right air temperature actuators:

B0361 and B0363 are for the left air temperature actuator
B0365 and B0367 are for the right air temperature actuator
The HVAC control module commands the air temperature actuators to move by controlling the voltage supplied on the control circuit. A signal voltage of 0 volts or a signal voltage of 5 volts rotates the air temperature actuator. A voltage of 2.5 volts stops the door. The HVAC control module determines the current position of the actuator by monitoring the voltage on the signal circuit. The feedback potentiometer is a function of the motor position. The HVAC control module controls the air temperature actuator door positions in order to maintain the selected air temperature.

Conditions for Running the DTC
The ignition is turned ON.

Conditions for Setting the DTC
The HVAC control module detects the signal circuit is less than 5 counts (0.09 V), for B0361 and B0365, or more than 250 counts (4.9 V), for B0363 and B0367.

Action Taken When the DTC Sets
A default value will be used for the sensor data by the HVAC control module in an attempt to maintain the air temperature selected by the driver. This default value will be displayed on the scan tool.

Conditions for Clearing the DTC
The DTC will become history if the HVAC control module no longer detects a failure.
The history DTC will clear after 100 fault free ignition cycles.
The DTC can be cleared with a scan tool.
Diagnostic Aids
A disconnected or broken door may also set this DTC by allowing the air temperature actuator to travel to its internal stops, an overtravel condition. If condition not present, refer to Testing for Intermittent and Poor Connections in Wiring Systems.

Test Description
The numbers below refer to the step numbers on the diagnostic table.

Tests for a default setting viewed by the scan tool.

Tests for the proper operation of the circuit in the high voltage range.

Tests for the proper operation of the circuit in the low voltage range. If the fuse in the jumper opens when you perform this test, the signal circuit is shorted to voltage.

Tests for a short to ground in the 5 volt reference circuit.

Simply put, its the drivers side actuator. Does it have an H or C code after it?

 

would having a vacume leak affect the actuator ?

 

where is the actuator ?

 

The actuator is located up under the driver's side footwell, right side on the hvac box itself. Its a pita to get too but it can be done. I did mine recently. Here was the cause of my code: Picture is of the driver's side actuator.

 

No.

 

H also Bo441 H

 

H is for history, C is for current. The code is not current.

 

Clear the code and see if it comes back. When you clear it, this forces the actuator to reset and retest itself.

 

thank you i cleared all codes i'll see tomorrow what happens

 

Just curious, you seem concerned with this code? Is there anything else happening with your AC system, or is all fine, but you have this code?

 

air is not coming out the proper vents or i should say it's coming out all the vents at the same time

 

Is this a dual control unit? IF so, and you cannot control where the air comes from in either auto or manual, than it sounds like a vacumn leak. Let us know if that is the case, as someone here will step in and tell you where to look.

 

My car suffers from a similar problem (02' zo6). Recently when i start my car about 85% of the time there is a loud vacuum leak or rushing air sound but once the motor runs for about 30 sec. or so the sound goes away. Or if I turn the A/C on while the sound is present it goes away and than returns if I turn it off


My A/C would start to blow cold than stop, I looked down at the A/C control and noticed the little orange light on the climate control would be blinking.

The car idols, runs and drives great

See profile for mods

 

 

idles

 

anybody???

 

You should start your own thread. If I was you, I'd be looking for a vacuum leak. Now if you are hearing this sound coming from the inside of the car, start there. But its its in the engine compartment, go there obviously. Pull your codes as a large vacuum leak will show up in the codes.
