Well, its fixed. Basically disconnected both window switches, fuse blew again so ruled them out. Having checked those, the instrument cluster and the gear knob plate (don't know the correct term) bit thats has the PRND12.All that was left was the heater panel. Removed that, disconnected it , replaced the fuse and it was fine but to get to the back I removed the radio and found 2 wires where the cables were exposed. Taped them up, replaced the heater and all is working. Thanks again for taking the time to help. Moral of this story is if a fuse goes buy a pack of ten just to be on the safe side, I have 2 left!!!.
