I was putting on a windshield coating, so I put the wipers in service mode and then tried to lift the arms up all the way (90-degree angle).
Now I didn't know until I read later from the service guide, that you aren't supposed to tilt the arms all the way, but rather just few degrees to allow getting the blades out. I anyways tilted them the whole way, felt a little resistance, continued anyways and then a small metal pieces crack off from the arm. The wipers still seem to be working fine but should I take them serviced anyways?
