Hello, I found two other posts but was hoping for more info or different insights. I have a Chevy Spark 2017 and I cannot get the back windshield wiper blade to disengage. I can tell its cheaper plastic and really don't want to force it anymore because I don't want to break it. I am also apprehensive about completely removing the blade because the plastic cap does not easily pop off and I don't want to break that either. Any advice? Cheers!
