You can see fuse, correct. With rear defogger turned on, use test light, see if any voltage at fuse or if fuse is blown? Also, check continuity on defogger grid, if no continuity, there is a break in the grid. If you can find the break, hopefully your local auto store has continuity paint that you can paint over the break to restore continuity.

Fuse box rear , fuse #23 30 amp ! Do you know where this is located ? There is also a relay for the Rear window defogger , located in the same rear fuse box .
Fuse Block - Rear
Left side of the luggage compartment, behind the left rear wheel well . But you really need to know how it works , you can check fuse an relay .
Rear Window Defogger Operation
Battery positive voltage is supplied through the BATT 1 fuse in the underhood fuse block to the rear defog relay switched input. When the rear defog switch button is pressed, the body control module (BCM) energizes the rear defog relay by providing a B+ to the control circuit of the rear defog relay. This allows battery positive voltage from the relay switched input through the switch contacts and out the relay switched output to the rear window defogger grid. The HVAC control module houses the rear defog switch and also illuminates the rear defog indicator on the switch button, upon this request. Ground for the rear window defogger grid is provided by G301 for the Sedan or G302 For the Extended Sedan.

rear window defogger ? it is fused in your fuse box ! and has a relay to activate the rear fogger ...right ?

Does the indicator light come on when you turn the defroster on? Have you checked to see where the wires come in on the rear window to see if they might have gotten disconnected. It usually happens right at the point where the wire connects to the grid.

The window defogger is often powered through a circuit breaker, which should be located at the driver's side fuse panel. If you have power at the window connector, likely the window grid may need repair. Toyotas have relays everywhere, but fuses are usually only under the hood in the Power Distribution Box, and at the driver's side fuse panel.

ck relay under hood for click when defog button is pushed,if this relay clicks switch and relay should be ok,just found same problem with mine,remove right kick panel where the little fuse box is located and large connector under it i seperated and found burned connector,cut wires on both sides and ran jumper wire,make sure to use proper gauge wire,now mine works good luck

All models have fuses, fusible links and relays found in various locations. One junction block (No. 1) is located within the cabin of the car, just under the extreme left side of the dashboard. This fuse block generally contains the fuses for body and cabin electrical circuits such as the wipers, rear defogger, ignition, cigarette lighter, etc. In addition, various relays and circuit breakers for other equipment are also mounted on or around this fuse block.

If you have a 12 volt test lamp, try this: Turn on the rear defroster. Attach the clamp to a good ground point; the door latch hoop is good)...Now, touch the test lamp to the extreme left and extreme right sides of the grids, on the inside of the glass. If the light does not light in either place, you probably either have a bad defroster relay, or the wires coming to the rear grids is off. Please feel free to get back to me with the results of your test.

There are 3 fuses that control the rear defogger, and 1 relay

The fuses are: 10 amp HEATER, 10 amp MIRROR-HEATER; under the dash
The 30 amp DEF fuse is in the fuse box under the hood
The relay is the DEFOGGER relay, which is on the back side of the fuse panel under the dash

Also, check for a loose wire on the defroster grid (on the back glass), this is the most common problem.
