My drivers seat will not move forward or backward and is now located in the full rear position. All the other seat functions are working up/down/tilt.
I removed the 2 front seat screws but cannot access the 2 rear screws because the seat being in the full rear position is covering the rear mounting screws. I have also removed the side panel holding the control switches. A fellow XF owner has provided me with another switch panel which I would like to install to see if the forward & reward seat switch will work and allow moving the seat forward.
Trying to disconnect and reconnecting the replacement switch panel is very difficult given the present conditions. My question is if I only connect the new F&R switch connector to the seat control and leave all the other switch connectors as connected to existing switches, will the F&R motor work? If this can be done I will be able to move the seat to allow accessing the rear mounting screws. I believe the F&R switch has a blue connector.
Also, is there another way to remove the seat?
Any help is appreciated.

 

Have you tried replacing the seat relay?

 

No, I have not because all the other seat functions (up/down/tilt) work. I have been assuming a single relay provides 12v to all the motor switches. If each motor has a separate relay then your suggestion is a good one. If this is correct, where is the forward/back motor relay located?
Do you know which connector goes to the forward/back motor? Knowing this might allow bypassing the switch and apply 12v directly to the motor.
Thanks,
Jack

 

Have you downloaded a copy of the manual? If you have a copy, then it’s best to review the area in question.
always best to be as aware of the situation on your own before you dive into this.

it’s usually faster this way too.

I have reviewed the wiring diagram in the manual and it shows a single relay controlling the power to the seats. As I indicated, all the other seat motors are working which to me means either the forward/rearward motor is not working or the switch is bad. I have another drivers side switch panel which seems to be in working order. My plan is to remove the seat and replace the switch panel.
Question: If the seat belt brackets are unbolted will the rear mounting screws be accessible?
Thanks for any help.

Unfortunately, removal of the 17mm bolt that fastens the belt to the side of the seat will not improve your access to the rear seat track bolts.

Brother, you appear to have a bit of a tough task ahead of you.

The only suggestion i can put forward is to work the bolts from the underside. I believe the seat track bolts go through the floor and are visible from the underside. Perhaps you can get them started with a pair of Vice grips. Not sure if it would work but at least it may be worth a try.

Please keep us posted.

 

I believe there is only one relay.

 

You haven’t made mention of the passenger seat, if stuck also then the relay is suspect.

 

The circuit diagram shows (1) relay which goes to the left and right seats. It feeds 12v to the switches controlling all the motors. Maybe I am missing something but if the relay malfunctions all of the seat motors will be affected.

 

Please, guys, its not the seat relay - that is clear from his posts. Please don't admonish him any more about reading the manual - it is clear he is on the right track.
I just don't know a way around this, my car is a base model, so I can't even go out to the garage and see what he's dealing with, as my car has none of this complexity.

You simply must get to those rear bolts. I know of a guy who has moved seats between cars quite often, perhaps he can help. I will message him on Facebook and ask him to drop in here.

 

Jack, I have a seat front to back motor if u need it. one other thing u might pull the seat forward as you move the sw forward or put a com-along on the front of the seat and put pressure on it """NOT much pressure jim

 

I plan on removing the 2 fasteners that attach the seat belt bracket to the seat rail. If that can be removed it might reveal the rear screw holding the main stationary rail. I looks like this bracket is also pinned to the frame. If necessary I can drill out the pin which will release the bracket. I also noticed a bracket held on with 2 screws that looks like it might hold the pinion gear that rides on the rack. If the pinion gear can be released this will possibly allow raising the gear off the rack and allow moving the seat. Are there any layouts, diagrams, or photos showing the location of the forward/reverse motor? All the documentation shows electrical block diagrams. It might also help to know which connector goes to this motor or what the wire colors are. I might be able to connect 12v directly to the motor and move the seat.

 

Here is a pass side mech, don’t know if it helps or if you need a different view let me know.

 

Thanks for the photo. The upper motor in photo appears to be for the forward/rearward drive which includes a reduction gear box. This looks similar to the driver's side seat. There are 2 screws attaching this unit to the seat rail. It looks like the output shaft from this drive connects with the rack mounted to the bottom track. If after removing the 2 screws supporting the motor and gear box to the seat frame, I might be able to slide the drive unit away or disconnect it from the rail. If this happens I will be able to manually move the seat forward. Another question, what color connector connects with the upper motor?
Thanks, Jack

 

White front blue back.

 

Jack, is there ANY way to tap into the plug for the forward/backward motor and momentarily apply power to it to move it enough to access the track bolts? It would only require a 12v battery and some wire attached to the motor plug connector. They are D/C motors and looks like they go until they run into the end of the track (no limit switch cutoff). Just be careful not to touch the battery post until your sure the connections are solid and EVERYTHING is clear of the moving seat. IF it is going the wrong direction, just reverse the wires at the battery. Most important, keep clear when applying the power!

When you have a high reduction gear box on an any motor it acts as a brake when a force is applied that makes the gearbox try and rotate the motor.
That is why you can bump start cars in first gear and not top gear.

 

Thank you all for the tips. I am very familiar with fraction HP DC motors and motors connected to gear boxes which are the components used to move the seats. I have been trying to find which connector attaches to the forward/reverse motor. This information is not indicated in the manuals that I have looked at. Once I located this connector I should be able to connect 12volts to it and manually jog the motor if it is working. Alternating the polarity to the motor changes direction of motion, understood. This would be very easy to do if the motors were accessible but having to work in blind quarters is not fun.

 

If unable to get to the under seat connectors, maybe the next step would be see if you can intercept them somewhere after the seat relay along the wiring? Good luck!
