SOURCE: 2001 Sienna rear window defogger doesn't work

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.

SOURCE: which fuse is for the rear window wiper and rear

You Have one fuse for the wipers in the car. Left side of steering wheel and the back cover should list the fuses and location. The other box is located in the engine compartment above the battery. They should list the fuse locations under the compartment covering the fuses. Hope that helps

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 ?

WHERE IS THE FUSE FOR REAR WINDOW DEFROSTER WHAT NUMBER FUSE IS IT IN THE 2007 ENVOY


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.

Which fuse do I replace for rear window defogger in a 2001 nissan almera


There may be a fuse in the fuse panel under dash, but defoggers are often found with a circuit breaker rather than a fuse. There may also be a relay in the circuit to the rear window. You could pull off the connector at the window, and with key on and defogger switch on, check for power at the connector. If you have power, one of the grid wires on the window may be broken. Kits are available to fix that.
If no power at the window, IDK, may have to find a wiring diagram, or have an electrician or mechanic start looking into it. Good luck.

Do you know where the rear fuse box is ?
Rear Window Defogger Description and Operation
Rear Window Defogger System Components
The rear window defogger system consist of the following components:
• HVAC control module
• Liftgate module (LGM)/endgate module (EGM)
• Rear window defogger grid
Rear Window Defogger Operation (With LGM)
Battery positive voltage is supplied through the LGM 2 fuse to the LGM for the rear window defogger system. 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 LGM to enable the rear window defogger. The LGM enables the rear window defogger by allowing battery positive voltage to the rear window defogger.
When the rear window defogger switch is pressed for the first time, the defogger cycle lasts 10 minutes. Further operation results in 10 minute defogger cycles.
Rear Window Defogger Operation (With EGM)
Battery positive voltage is supplied through the EGM 2 fuse to the EGM for the rear window defogger system. 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 EGM to enable the rear window defogger. The EGM enables the rear window defogger by allowing battery positive voltage to the rear window defogger.
The following conditions must be met for rear window defogger to operate:
• The end gate glass position is not below the index position.
• The window express down movement is not requested.
• The window down movement is not requested.
If the end-gate glass is not fully closed, the DIC displays "Tailgate Glass Down" when the rear defogger operation is attempted.
When the rear window defogger switch is pressed for the first time, the defogger cycle lasts 10 minutes. Further operation results in 10 minute defogger cycles.
