Windshield wipers got tangled up in each other. ice gets on them and they break instantly. i believe that chevy knew this would happen but didn't care. my van is a lemon and since i bought it it's been a money pit. it has less than 50,000 miles on it and it stinks. nothing but trouble. i've also had to get a head gasket at the tender miles of 38,000. it's just a lemon. it's not safe to drive in the rain, or snow if you can't get your wipers to work. wish they'd design the wipers they are shaped funny, and that's one thing that makes them not work well. *tr
