Chosen Solution

I have a 2003 Forester with aged bushings in the wiper transmission linkage. I need to remove the wiper arms, so I can get access to the linkage under the cowl between the windshield and the hood. But I can’t fit any tool (screwdriver, gear puller, battery terminal puller, etc.) without damaging the cowl. How do I remove the wiper arms?

Hi, Here are some images taken from the 2003 Subaru Forester service manual Body section, showing how to remove the wiper arms and the wiper motor and linkage and cowl etc.
