Ive got friend who work for seat dealership. He checked the car andsaid that these 2 parts have to be replaced. So i just trying to save money by doing DIY really
Ah, okay, so you are just a bit unlucky then!
Its really just down to buying the correct versions of these two parts, getting the inside cover off the hatch, remove the wiper and its arm, remove the nut (maybe forgotten if one holds the weather seal on), unclip the wiring plug, unscrew three or four securing screws/bolts, unplug the water pipe, swop motor assemblies and reverse the first few steps. Getting the rear lock off is a similar exercise.
