Switch pack failure

[skeltz]

After rebuilding my 98 xkr engine checking the car for an mot was surprised to find front & rear fog lamps, heated seats , traction control , headlamp height all in the same switch cluster do not operate only the hazard lights work all these functions worked fine previously I would be surprised if the switch pack has failed any electrical gurus out there can point me in the right direction maybe have access to a wiring diagram to see if there is a circuit that may be linked ?
