With a volt meter or a test light ,it also might be a fuse
On the 98 Beetle, the rear defroster fuse is located under the dash. It is found in the number eight slot.
Check that the wire on the rear defroster is connected to the defroster. If broken off repair it.
what are the colors of the wires for the rear window defroster coming from the rear window to the defroster bottom ? can any body help me
Check your fuses.
Check to make sure your rear window is not down a little bit. I could not get the rear w/s wiper or the rear window defroster to work until I lowered the rear window and then closed it again. Problem solved. Hope it works for you, too !
Your rear defroster heat grid is also your radio antenna. check for grid problems.
It is part of the rear window defroster.It is part of the rear window defroster.

You can get the fuse for 1998 rear window defroster at the NAPA, Auto Zone.
The 1996 Chevy Cavalier rear window defroster fuse can be found in the fuse box. The rear window defroster fuse will be in the second column, fifth from the top.
Check the fuse first. Then check, with a volt meter, to see if there is 12 volts D.C. to the defroster at the place where it is plugged in. If you have voltage then look at the defroster heat strips and check for a break somewhere. There are repair kits for a broken power strip. If the fuse is good and you have no voltage, check the wiring, switch, & relay.
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.
