Sadly, a 4 door car needs the rear window removed. A 2 door will go out the side, but there is no way short of folding it in half in a 4 door.

The window will come out by removing the wires from the heater- the connectors are hidden under the c pillar trim- then push the window out, using even pressure-use a screwdriver to help fold the rubber out from the top corners. The rubber goes with the window. Don't get too rammy, and once the top is loose it should come the rest of the way easily. Watch the rubber across the bottom of the window- if it sticks down the chrome strip will pop out of the rubber, and it is a cast iron b--ch to reinstall.

Reinstallation needs a length of 1/4 inch or smaller rope- the smoother and slipperier the better. Lay it into the groove in the rubber, overlap the ends of the rope at the center of the bottom of the window, have someone push the window as you pull the rope tofold the rubber back around the body. The corners are tough, so work slowly, don't pull the rope too fast, keep settling the window down as you go, finish at the top. Some lubricant on the rubber helps- WD-40 is good but leaves a mess, spray glass cleaner works but has to be reapplied as it dries off. Good luck, and always use the flat of your hand- never a fist.
