Back Window Defroster

electric back light. a fancy name for rear window defroster
There can be several reasons a rear defroster fails even when the light on the defroster switch indicates it is on. The most likely reason is that one of the metal defroster tabs along the side of the back window has separated from the defroster. If the defroster tabs check out as still attached to the defroster then you need to do a little checking with a volt meter. The first thing to check is the voltage directly on the tabs themselves. This should be around 12-14 volts. If the voltage is zero then there is very likely a broken wire someplace between the defroster relay and the defroster. If you have 12-14 volts a the defroster tabs then there is something going on with the grid which is normally broken defroster elements, those long thin horizontal lines on the back window.
EBL is an abbreviation for electronic back light That is what Dodge calls the rear window defroster.
On my 2005 Pacifica, the antenna is located in the passenger side trunk window. Looks similar to the defroster wires that are on the back window

It is attached to the back window, it looks like one of the wires from the defroster. If you look close you can see it.
Chrysler uses that abbreviation for "electric back light" which is what they call a heated rear window defroster.
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.
On the back of the mirror, there is a small heating element. The element heat the mirror the same as the defroster on a rear window.
