We reclined The passenger seat and now the motor will not bring it up. Other electronics on the seat work but not the repositioning the seat back.

 

The switch packs can play up on these cars. The seat modules are also a common issue. Do you hear any clicking noises when trying to move the seat back up? If not, it may be the motor, the module, or the fuse has blown.

 

More than likely, it is the control module. It is a grey plastic box located under the seat, near the front, one module per seat. At this point, it is best to swap the driver and the passenger module to see if the problem "moves" with the control module. If so, the module is damaged and need to be repaired ($100?). This is a very common problem.

Adjust the seat bottom all the way up for clearance. Remove 2x10mm nuts and 2 or 3 plugs in the back of the module. The seat does not need to come off.

Best of luck, keep us posted.

This is a common problem and usually has to do with the tracks near the edge of the seat control module PCB rubbing on the case and wearing away. These can be fixed by soldering a wire bridge across the track break. The worn away track(s) are fairly obvious, and continuity or lack thereof can be checked with a multimeter (scrape the track clean for a good connection). If you are OK with using a soldering iron you could try fixing it yourself. See JagRepair.com - Jaguar Repair Information Resource
Otherwise, there is at least one person on the forum, I believe (Darrell Turner?), who will provide a mail-in repair service.

 

Before you go too deep, try removing the switch from the side of the seat, open it up by removing the small torx screws in the back, and press the actual electronic switch on the circuit board. The problem could be the exterior plastic switch "handle" (for lack of a better description) and not the electronics. Been there, done that.
