You should be able to push the window to one side and then it should come right out. The frame of the window has springs on one side that hold it in the frame. This is how I replaced my broken glass in my Compact Jr. Please let me know if this works for you
I was trying to slide it to the wrong side. Once you told me about the springs I knew I had to slide the window toward the springs -- the side that looked the "emptiest". The windows
popped right out.
Thanks for your help -- now off to Home Depot for the glass and safety chain, KMart for the side marker lights
(the contacts of the old ones are too corroded), then I'll be ready for the DMV tomorrow.
