Hi Igor, the wiper motor is behind the cowl cover, the outer grills have to be removed first then the center cover comes off. The grills have pins that must be pried out and the cowl cover has pins that must be pushed in.The pins and holders are kind of like drywall anchors, they expand when the pin is inserted so remove the center part first and then the holder.Good luck.
