x351 panoramic roof not working

[grahamwturner]

good day to you, i had my XJ (x351) engine let go big time, i managed to source a low milage engine from an  rear end accident damaged  car, the car went to a jaguar landrover specialist to have the change done, since i got it back i have 2 faults,  fan 1 control circuit and the pan roof is not working, any advice would be appreciated, i have done the obvious reset holding the forward button on the roof also checked every fuse in the 3 fuse boxes and none had blown, obviously the battery was disconnected for quite a while, not sure if this might have any bearing on the problem at all.

any help or advice that i am able to do myself i would be grateful, i am pretty handy with a spanner so willing to have a go, plus after paying for a replacement engine and fitting has left the coffers somewhat low, 

many thanks for any help
