Either your control module is burned out or your window contacts have become detached. Permatex offers an electrically conductive adhesive for the latter (less than $10). For the module, it's a combo radio antenna and defrost control. It's located on passenger side in back at the pillar. You have to take off the fabric panel to get to it.

Which fuse box on the 2011 Chevy Malibu is the fuse for the rear defrost


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.

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 ?

How come on my 2005 pontiac aztek if i take out the rear defroster fuse (#21) the light still lights up on my dash and the relay still clicks?? Help why did this rear defroster stop working?!?


I found this. Your heated mirror also works off that relay. You can do ohms test on the grid, if the grid is open, no continuity. The auto store should sell a product to paint over the open spot to restore continuity, if you can find the open spot.
Not trying to cause trouble, just killing time. Have a good day.

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.

Rear defogger/defroster is out in my 2007


The 30 amp fusible link located in the drivers side junction block controls power to the rear defoger. It is larger than a regular fuse it is pink and has a clear top.
The easiest thing to check first is just touch the terminal on the rear glass with a 12 volt test light or a DVOM to see if you have power.

Rear defogger for toyota 4runner


most likely its a linkage assembly in a/c controls that the linkage somehow binded and is not makeing a full contact
check the fuses and engine compartment relays

for the defoger on the rear pull the door panel off use a test light to test the leads so that you can get a good connection

most likely the wireing is not the cause and i recommend checking the linkage to or relay, fuse to the rear defoger
