stupid question but how to i take off the damn windshield wipers? i bought some teflon wipers the other day and yesturday when i tried to put it on. in the 4 years i had my car, i never changed my wipers because they just started leaving streaks recently. but i spent 15 mins trying to get it off but i couldnt, so then i just gave up and watch some tv. i think something is stuck or i am doing something wrong. there was a clip button thing on the wiper and i when i press it and pull it, nothing comes out or moves. i tried sticking a flat head and try to kinda pop something lose but nothing moved. its kinda stupid that i can rebuild motors but i cant take that damn wiper out.
