2001 Sienna rear window defogger doesn't work

I'm guessing there are one or more fuses and probably a relay involved. Does anybody know the location of the fuses/relay for the rear window defogger? (the owner's manual isn't specific about even the fuses).

Thanks in advance

    2001 Sienna's rear window defogger wires have come undone from the window (under the plastic molding) must we use some type of specific adhesive?

    Thanks

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.

Wiring diagram for rear window defogger 2005 silverado from dash to deffoger


Rear Window Defogger System Components
The rear window defogger system consist of the following components:
• HVAC control module
• Body control module (BCM)
• DEFOG relay
• Rear window defogger grid
Rear Window Defogger Operation
When you turn the ignition to the ON position, ignition voltage is supplied to the DEFOG relay coil. Battery positive voltage is supplied at all times to the DEFOG relay switched input. When the rear window defogger switch is depressed, the HVAC control module illuminates the rear window defogger indicator and sends a class 2 message to the BCM. The BCM energizes the DEFOG relay by grounding the control circuit of the 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. Ground for the rear window defogger is provided by G306 or G390 (crew cab).
When you turn ON the ignition and press the rear window defogger switch for the first time, the defogger cycle lasts 10 minutes. Further operation results in 5 minute defogger cycles.

Do you know what your messing with ? What's the problem ?

My rear defroster won't work I have a 2000 Buick Park Avenue


Could be a bad relay !
The rear defogger circuit is protected by a 40A fuse. Voltage is supplied through the fuse to the rear defogger relay. When you press the rear defogger switch, the heater and A/C programmer sends a class 2 message to the body control module (BCM), to ground the rear defogger relay coil output circuit. This in turn closes the relay contacts allowing current to the rear window grid.
Do you know what a class 2 message is ? What a BCM is ?

Defogger window wont work


front or rear.?
my guess, wild is, the rear electric defogger, is dead.
the test is so easy.
attach any voltmeter to the 2 grid terminal. and turn the defroster on.
12v there? yes, then the grid is open.
no> the relay that feeds it is bad. (or its controls or FUSE is blown)
check all fuse first.

Rear window defogger stopped working


In the fuse block, you will find 25A FUSE 17 which feeds the rear window defogger relay coil and 30A circuit breaker 4 which feeds the contacts.

I have a 1990 Ford Taurus and my blinkers don't


blinkers sounds like the flasher unit is not working. It's located under dash. Also check for burnt out bulbs.
Rear defrost, or rear defogger?: Your defogger for the rear window would run off a relay, probably located in the fuse panel of your car. Often, the connections at the rear window get broke or disconnected.
Front defrost: does your heater blower work?

I have an '03 Olds Alero and the rear defrost is not working...replaced the relay....switch lights up and continuity is good across the grid. I put the relay in both ways..not knowing if it makes a...


The relay can go in either way--no problem. The relay runs off 2 different fuses--one to power the relay itself and one to power the defogger. Make sure both fuses 33 and 46 in the engine compartmet fuse box are good.
Next, have someone listen to the relay while you turn on the defogger to see if it's clicking. If it isn't clicking, the problem is before the relay--probably in the control panel.
If the relay is clicking, the problem may be with the antenna amplifier (radio borrows the defogger grid to improve reception). Not sure where that module is but would guess it's in the right pillar by the passenger's fuse box. If you can find it, check continuity across the 2 black leads. Also verify the back side of the defogger is getting it's ground.
Please let me know if you have more questions.
