My DS door handle has had a crack on one end for a couple of years so took the opportunity to fix it while the door is apart. Once I had the handle assembly on the work table I disconnected the spring, washed the area around the crack, scuffed the plastic up on both sides of the crack with 400 grit sandpaper, took a small file to gouge it a bit along the crack, cleaned the area again with a solvent, let it dry, then applied Loctite two part epoxy for plastic. Held it tight for five minutes then let it sit overnight to fully cure before reinstalling.
