The easiest way is to use a cheap volt ohmmeter and check the voltage where the wires hook to the gas struts that hold the window open. You should also check the (4) spade connectors for corrosion and make sure they are seated tightly, also, check where the wires from the struts connect to the heater element. If they are loose or broken off you have to re-connect them. Some people have had luck with electrically conductive glue, on mine I had to use a low wattage soldering iron (40) watts and fine rosin core solder. Also check the wire grid on the rear window for breaks. Repair kits are available at any auto parts store. You can get an inexpensive volt/ohm meter at Radio Shack for less than $20.00. Work backward from there, check the fuse and then the switch.
Good luck and I hope this helps.

One end is grounded and the other has 12 volts. Use a meter or test light to see if you have power at one end. No power then look for the fuse under the dash or possible bad switch. If your looking to find a broken line on the glass. Use a volt meter set to 20 volts or so. Start on the end that has 12V pos. Slide the probe tip down the line, as you go watch the meter, it will read nothing at first, when you cross the break it will start reading. Repair with a commercial repair kit (10-15 bucks).

My guess: one of the wires that connects from the hydraulic lift piston to the grid or from the grid to power or ground may be shot
Check then all with a multimeter, but you may have only a few strands left hangin...You can solder them back together
