How do you remove windshield wiper arms from a 1990 Chevy suburban?

Answer 1

I recommend using an awl for this, but a good pair of needle nose pliers will work. You'll also need a large screwdriver. First, remove the washer fluid line from the wiper. I'd use a grease pencil to mark the position of the blade on the window to made intallation easier. On the wiper arm, there is a little 'U' shaped tab, which is spring loaded and fits into the groove of the wiper motor pinion. Using the awl (or pliers), pry the tab away from the pinion, and using the screwdriver (wrap the screwdriver in a rag or something similar to prevent scratching your paint!) pry upwards on the arm. The arm itself has a strong spring on it, so you might have to lift on the wiper to help in getting it off. There might be a tool for this job, but since I'm a self-taught shade-tree mechanic, I use what's at hand! Good luck.
