How do i fix a stuck blend door on 2010 dodge nitro?


I would pull off the blend door actuator and swap it out with a new one. Or another option is to swap it out with one of the other actuators. The blend door actuator is interchangeable with the actuators for the mode-air doors and the recirculation-air door.

Disconnect and isolate the negative battery cable.

If equipped, remove the silencer from below the driver side of the instrument panel.

Disconnect the wire harness connector from the blend door actuator located on the driver side of the air distribution housing.

Remove the two screws that secure the blend door actuator to the actuator mounting bracket and remove the actuator

Need info on heater mode door operation


The mode door actuators are reversible, 12-volt direct current (DC) servo motors. The heating-A/C systems on this vehicle use two mode door actuators. One for the panel/floor-air door and one for the defrost-air door.

Both the defrost door actuator (1) and the panel/floor door actuator (2) and the are located on the driver side end of the HVAC housing (3), close to the dash panel.


All actuators (1) are interchangeable with each other. Each actuator is contained within an identical black molded plastic housing with an integral wire connector receptacle (2). Each actuator also has an identical output shaft with splines (3) that connects it to its respective door linkage and three integral mounting tabs (4) that allow the actuator to be secured to the HVAC housing. The mode door actuators do not require mechanical indexing to the mode-air doors, as they are electronically calibrated by the A/C-heater control.
OPERATION

The mode door actuators are connected to the A/C-heater control through the vehicle electrical system by dedicated two-wire leads and connectors of the HVAC wire harness. The mode door actuators can move the defrost-air door and the panel/floor-air door in two directions. When the A/C-heater control pulls the voltage on one side of the motor connection high and the other connection low, the mode-air door will move in one direction. When the A/C-heater control reverses the polarity of the voltage to the motor, the mode-air door moves in the opposite direction.

When the A/C-heater control makes the voltage to both connections high or both connections low, the mode-air door stops and will not move. The A/C-heater control uses a pulse-count positioning system to monitor the operation and relative position of the mode door actuators and the mode-air doors. The A/C-heater control learns the mode-air door stop positions during the Actuator Calibration procedure and will store a Diagnostic Trouble Code (DTC) for any problems it detects in the mode door actuator circuits.

The mode door actuators are diagnosed using a scan tool (Refer to 28 - DTC-Based Diagnostics/HVAC - Diagnosis and Testing).

The mode door actuators cannot be adjusted or repaired and must be replaced if inoperative or damaged.

No heat Heater core is hot


If heater core is getting coolant circulating through it then you may have a temp blend door, or blend door actuator not working properly. The blend door is located in the air box under the dash, and the actuator is located on the air box. You may be able to visually check the operation while turning the temp knob, by locating the coresponding actuator on the air box and monitoring the movement. If it is moving ok and still no heat then the blend door, or lever is broken, which will require removal of the dash.

Heating system only blows out hot air through the vents


I would look at the air blend doors first, it sound like they are not working or your control in the dash is not working send a signal to them. they work by changing the air from hot to cold or in between.
