Check the fuse for the defroster first. if that's still okay, the defroster grid may have been damaged

SOURCE: My rear window defrost doesn't work

Using a 12 volt test lamp, check for power at the connection to the grid. If no power there, check fuses, and switch. If there is power at the connection, look closely for a break in the continuity of the grid. Usually right near where the wires connect. If broken, parts stores can fix you up with a conductive glue. Common problem, and the glue is cheap, and works great. Good luck!

I have a 2007 dodge magnum with limo tint windows!My side windows don't defrost however the windshield and rear window defrost just fine and my heater works great!

Your windshield and rear window has defrost outlets that exhaust right onto your front and rear window glass. Your side glass probably doesn't enjoy this luxury.

Windshield wipers stop working when the defroster is on

The only thing they have in common is the ignition switch.

Rear defroster lights up, but does not defrost, also very weak car radio reception.

Between the rear passenger window and the back window is a junction where rear defrost wiring and radio antenna connect. Rear defrost wiring becomes loose and burns this unit out. when looking for replacement at salvage yard everyone of them I found had burned up. Lots of La Sabres w/o working rear defrost. I made solid connections for defroster, and added an antennae, not much point in repeating a system that will fail again.

rear defrost will not work with the following reasons one the fuse could be burnt, 2 the wire going to the rear defrost could be broken, 3 there is a break in one of the lines on the rear window, 4 where the connector is to the rear defrost it could have either broke at the window or the solder let go

I have a 2003 Alero, replaced relay switch and fuse under the bonet for the rear defrost, all wires hooked up...no lines broke.. rear defrost button lights up , but rear defrost dont work. Are there any...

There is a connector going to rear defrost on the rear window. Disconnect this and check for voltage with defrost on. If this is good, check resistance for the connection to window. This will tell you if the electrical is working or the element is bad for the window if there is a open reading on multimeter.

2004 4Runner Rear Wiper and Defroster won't work

I just had the same problem. I have an '04 4Runner and my rear wiper, fluid wash, and defrost stopped working after it was recently serviced. If you had the battery cables disconnected recently here is the solution...Start the engine and lower the rear tailgate window all the way... close the rear window and then turn the engine off. Restart the engine and the wiper,wash, and defrost. should work again. It has something to do with the computer which needs to be rebooted. Good luck.
