Hi I have a problem the drivers power seat won't go backwards or forwards

 

The pinpoint tests for this scenario from the Workshop Manual are limited to checking the harness for continuity and powering the fore/aft motor directly to eliminate component failure:





Beyond this it becomes a matter of checking for fault codes but this requires Jaguar SDD (Symptom Driven Diagnostics).

Seat Modules are a regular problem with several Jaguar models. Fitted beneath the seat cushion, they are subjected to frequent flexing in normal driving and this often breaks tracks on the circuit board. A method of checking modules on XJ and XK models is to (temporarily) swap driver and passenger to see if the fault moves too. I don't know if X250 is the same but Jaguar tend to replicate design principles across models and it would be odd if the XF is different.
