Question about 2006 Nissan Armada

1 Answer

Actuator that controls air flow to floor

The actuator that controls air flow to floor is rotating 180 degrees and closing back off, when it should only be rotating 90 degrees. I replaced the actuator and this still happens. What tells that motor to stop?

SOURCE: Interior thermostat control is stuck in position

check fuses and relays. there is an electric motor that opens and closes a "blend air door' that switches from hot to cold. the other lights may or may not be related. Is is very possible that the plug going into the control unit has a bad connection.

Can you diagnose your own vehicle?

Then you need to go to someone that can

You should not be using it, no matter what
research you do,as you have a check light on & as
you said, don't have a definite diagnoses.

A TPS Sensor will cause several problems, but not likely
to the point it would die.

The a/c system is fairly comples, and there are several things that could contribute to your problem. may be the belt is loose, the bearings are out on your tensioner, the compressor is bad, or the refrigerant is low.

2008 silverado EGR location on a 5.3 fuel injected v8


Doesn't have a EGR valve ! Has Camshaft Actuator System .
Camshaft Actuator System Description
The camshaft position (CMP) actuator system is used for a variety of engine performance enhancements. These enhancements include lower emission output through exhaust gas recirculation (EGR) control, a wider engine torque range, improved gas mileage, and improved engine idle stability. The CMP actuator system accomplishes this by controlling the amount of intake and exhaust valve overlap. For the 6.0 liter (LY6, L76) and the 6.2 liter (L92) engine, the Park position for the CMP actuator and camshaft is 8.5 degrees before top dead center (BTDC) or 17 crankshaft degrees BTDC. The engine control module (ECM) can only command the CMP actuator to retard the valve timing from the Park position or advance the valve timing back to the Park position. The total range of valve timing authority is 31 degrees camshaft rotation, or 62 degrees of crankshaft rotation. The control range is from the Park position of 8.5 degrees camshaft or 17 degrees crankshaft BTDC, to 22.5 degrees camshaft or 45 degrees crankshaft after top dead center (ATDC).

Having problems with climate control. Temp setting does not come back on to the last setting it always comes back on at 75. Also when pushing the front defrost it doesn't blow air.


You may want to have it check for DTC'S diagnostic trouble codes . A code may point to the problem , these HVAC systems are very complex .
DTC B0248, B0268, B0408, B0418, B0428, or B3531
The HVAC door actuator is an electronic motor with a feedback potentiometer. The HVAC control module supplies power and ground to the actuator. The HVAC control module controls the direction of the actuator by changing the polarity of the control circuit. When the actuator reaches the desired position, voltage is removed from the control circuit. The HVAC control module determines the current position of the actuator by monitoring the feedback voltage of the door position signal circuit. The feedback potentiometer position is a function of the actuator position.

Where is the EGR valve located?


Doesn't have or need an EGR valve it has Camshaft Position (CMP) Actuator System
The camshaft position (CMP) actuator system is an electro-hydraulic operated device used for a variety of engine performance and operational enhancements. These enhancements include lower emission output through exhaust gas dilution of the intake charge in the combustion chamber, a broader engine torque range, and improved fuel economy. The CMP actuator system accomplishes this by changing the angle or timing of the camshaft relative to the crankshaft position. The CMP actuator simply allows earlier or later intake and exhaust valve opening during the four stroke engine cycle. The CMP actuator cannot vary the duration of valve opening, or the valve lift.
During engine OFF, engine idling conditions, and engine shutdown, the camshaft actuator is held in the park position. Internal to the CMP actuator assembly is a return spring and a locking pin. During non-phasing modes of the camshaft, the return spring rotates the camshaft back to the park position, and the locking pin retains the CMP actuator sprocket to the camshaft. The park position for the CMP actuator and camshaft is 8.5 degrees before top dead center (BTDC), which is equal to 17 crankshaft degrees BTDC. The engine control module (ECM) can only command the CMP actuator to retard the valve timing from the park position, or advance the valve timing back to the park position. The total range of valve timing authority is approximately 20 degrees of camshaft rotation, which is equal to 40 degrees of crankshaft rotation.
CMP Actuator System Operation
The camshaft position (CMP) actuator system is controlled by the engine control module (ECM). The ECM sends a pulse width modulated 12-volt signal to a CMP actuator solenoid to control the amount of pressurized engine oil, into the CMP actuator. To regulate the pressurized engine oil into the CMP actuator, the solenoid uses electromagnetic force on the solenoid pintle to pulse the oil control spool valve. The pressurized engine oil is sent to unseat the locking pin, and to the vane and rotor assembly of the CMP actuator, to either retard or advance the valve timing. The ECM will control the amount of ON time applied to the solenoid.

The heater/vent system will not blow warm/hot air even when dialed to 90 degrees on climate control


On a newer truck such as yours, the problem is usually the blend door actuator. First try a recalibrations of the system. Remove the HVAC fuse for a couple minutes and then put it back in. Start the truck and let it idle for a few minutes. Check to see if that fixed it.
If not, next check the actuator. I will paste instructions below for taking it out. Once you have it out, plug the connector back in and see if it turns when you change the temperature control. If not, the problem can be in the controller or the actuator. If it is clicking, the problem is stripped gears. If it isn't doing anything, you can check for voltage at the connector with a voltmeter. Connect the black meter lead to a good ground point and probe the connector terminals with the red lead while changing the temperature setting. The part costs $140, so do what you can to make sure it's bad before putting a new one in. Also, it may be worth your time to read my post at http://www.fixya.com/cars/r6235876-no_heat_fan_blowing_cold_air for other ideas. Please let me know if you have questions.

The auxiliary A/C and heating system has the following features:
  • The auxiliary A/C and heating system is functional whenever the instrument panel mounted A/C control is in any position except OFF.
  • The auxiliary blower motor recirculates the air inside the vehicle. Outside air is not available to the auxiliary system.
  • Air is cooled and dehumidified by the auxiliary A/C evaporator core only if the instrument panel mounted A/C control is adjusted to a position that requires A/C compressor operation.
  • The temperature blend door and the auxiliary mode door are controlled by electric actuator motors.
  • Movement of the auxiliary temperature control between COOL and WARM causes a corresponding movement of the temperature blend door to mix air flowing through and around the auxiliary heater core.
  • Movement of the auxiliary mode control between PANEL and FLOOR causes a corresponding movement of the auxiliary mode door to direct air flow between the panel (headliner) registers and the floor duct.

I would say the auxiliary mode door (#4) electric motor is not wokring.
