window trim removal

can someone tell me how to remove rear glass trim with out messing it up. thanks

Tiny -You'll have to buy a simple tool. It's basically a flat piece of spring-like steel that has a hook at each end and a raised handle. It slides UNDER the trim and disconnects the trim clip. They work pretty well. Best news is that they are inexpensive. Any good auto parts store will have one for $10 or less, look for one specific to GM cars.
Don't try to pry the trim up without one of these - or you will bend them and the clips will be twisted out of shape too.
