How recline rear seats on a 2005 Pacifica 3.8

If the rear seat of your 2004 Mitsubishi Endeavor is not reclining, there are a few potential causes to consider:

1. Broken recline mechanism: The recline mechanism, which is located under the seat, may be broken or damaged, preventing the seat from reclining. You can try to manually operate the recline mechanism to see if it is working properly.
2. Obstruction: There may be an obstruction, such as a foreign object or a piece of debris, preventing the seat from reclining. Check under the seat for any visible obstructions.
3. Wiring issue: There may be a problem with the wiring or electrical system that is preventing the seat from reclining. Check the wiring under the seat for any visible damage or loose connections.
4. Fuse issue: The fuse for the seat recline function may be blown, causing the seat to stop working. Check the fuse box in your vehicle to see if the seat recline fuse needs to be replaced.

If you are unable to identify the cause of the problem and the seat is still not reclining, it is recommended to bring your vehicle to a mechanic or a dealership for further diagnosis and repair.

Rear Seat Switches
There are three push button switches that are used to operate the power folding seat; front stow switch, rear stow switch, and recline switch. The front stow switch is located in the right rear quarter trim panel just behind the second row seat. The rear stow and recline switches are located in the right rear trim panel just inside the liftgate. Battery positive voltage is supplied at all times to all three switches from the FFS SW Fuse located in the left rear fuse block. The folding seat will operate only in a supervised mode, i.e. press and hold the selected switch button through the entire cycle of operation, or release the switch when the desired seat position is reached. When any folding seat switch is pressed, it sends a 12 volt signal through the switch signal circuit to the RSM. The RSM then commands the appropriate seat motors to move in response to the switch signal.
Rear Seat Module and Power and Ground
The rear seat module controls the position of the third row seat. When commanded it moves the seat from the seated position to the stowed position, or, from the stowed position to the seated position. With the seat in the seated position, the RSM can also move the angle of the seat back forward or rearward.
Battery positive voltage is supplied at all times to the module through the battery positive voltage circuit and the FFSM fuse located in the left rear fuse block. This voltage is used to power up the RSM and also to apply power to the seat motors when commanded. The RSM is grounded through the module ground circuit and G401.
The first place to start would be check the fuse's .Do you know where the left rear fuse block is located ? Fuse Block - Left Rear
In the passenger compartment, near the left side of the rear seat under the carpet
If the fuse is good next thing to do would be ,have check for DTC'S in the rear seat module ! This has nothing to do with check engine light or OBD 2 diagnostic trouble codes an a code reader for said OBD2 codes will not work . Would need a factory scan tool to check these codes.
DTC B1395
Battery positive voltage is supplied at all times to the rear seat load floor switch and the rear seat position switch by the rear seat module (RSM). The RSM monitors these battery positive voltage supply circuits for the protection of internal circuitry of the module.
DTC B1395 Device Voltage Reference Output 1 Circuit
DTC B1420 Device Voltage
Battery positive voltage is supplied at all times to the seat adjuster switch and the memory seat module (MSM) through the same circuit. The MSM uses this battery voltage input to determine if battery positive voltage is applied to the seat adjuster switch.

Just from looking at the factory service info , I'd say you would be bet off just taking this to the dealer !
The first plase

The rear seats in the Nissan X-Trail 2.5i V slide, recline, fold flat, and, if you're willing to take a socket set to your car, are easily removed. Taking out one or both seats really increases the cargo space.

You do not say what design 3 series; but for E36 with electric seat adjustment, Odometer Gears (link below), makes replacement gears for the electric seats for approximately $40 each. This is the part that typically wears/breaks for seat reclining.

If you look under the seat, you will find several motors. For reclining there could be a few of options to check. Motor being one, and linkage being one, and just wear and tear on the swivel points. Hate to say this, but weight of the person can make a big difference on all I mentioned.

seat recline motor stuck or unplugged

If you pop the back panel off your seat on the bottom right hand side you will find the motor for the recline and it has one T30 bolt and a shaft going through the center witch if you remove the clip on the right side of the shaft it will slide out far enough to remove the motor.Follow the wire down to the bottom of the seat almost to the floor the plug is there. When putting in the new motor it is easiest to have some one help you by pushing the button back and forth to line up the shaft and bolt hole.hope this helps you out.

I have the exact same problem and I am wondering if you've found the source of the problem??
