to remove the plastic trim there is 2 screws i think there are philips there in side the handles on the trim. after you unscew them the trim just pull off it has clips all round the edge, u mite need to lever the edge with a long flat scew driver to pop the clips out. thats who to get the trim off. but first you need to remove the wiper, you remove the black cover on the base of the wiper and there is a 13 bolt under it, undo that and pull the wiper off. then under the trim the motor is held in by 3 10mm bolts i think, undo them then you can pull the motor out. hope this helps
