First things first, make sure that the wires are connected at BOTH sides of the rear window for the defroster. There needs to be a path for the burrent to flow, so both need to be connected. If not, you can purcahse kits to re attach them, or if you are handy enough...solder it yourself. If they are connected, push the button that turn the defroster on...if you hear a click or a change in the sound of the engine (like its under load) then the defroster is working, but you have a connection problem between the device up front and the wires on the window. hope that helps

Try this simple fix. Put the window down then put it all the way back up. Over time and a few bounces the rear window settles down just a bit and this triggers a safety that prevents the defroster from running with the window down, only it's not down enough for you to notice it.
