SOURCE: 1989 Buick Century passenger side rear window will

I would see if the haynes manual or chiltons manual has specs for the driver (main )switch so you can test ressistance. Sometimes when they go bad they can show up in one door, also verify voltage to the side rear window switch, as well as ground , the wire colors and location should be in the manual also, if everything checks out there start leaning toward the motor ,in that case you need to trace wire colors as well as schematics (manual), and bypass the switch to the motor directly this should identify yor culprit. hope this helps chris

SOURCE: Rear window defogger doesn't work.

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.

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 ?

I have a 95 Grand Am GT 3.1 rear defroster is not working where are the fuses and relay for the rear defroster


Have you done any testing? If not, find the connector for rear defogger grid, probably in the trunk, somewhere. The purple wire is voltage, the black wire is ground. Turn on defogger, use a testlite between terminals, if the lite comes on, the problem should be with the defogger grid, itself. You can check for continuity in the defogger grid. If no continuity, there is a break in the grid, If you can find the break in the grid, the auto store should have this stuff that you can paint over the break allowing continuity in the grid.

I'm just trying to pinpoint problem.

I'm a jack of all trades and a master of none.

My 2004 6cfl. Trailblazer rear window defroster is not working. The wires appear to be making a good contact. The outside mirrors defrost ok using the same switch as the test window defroster. Is there...


There is a module that controls the rear window defogger grid . LGM/ EGM Liftgate or endgate module .Receive's message on class 2 serial data network from the HVAC control module to turn it on when button pressed . Fuse # 3 30 amp located in the rear fuse box . 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.

Hyundai XG350 rear defogger doesn't work. I have changed the relays, checked all the fuses all good, dash switch works because I changed that too. checked the wire to the grid thats' ok too. now what?


The rear defogger is controlled by the Electronic Time and Alarm Control Module (ETACM). It receives a signal from the switch, and if the car is running, turns on the rear window defogger. Most frequently the problem is a blown 30A defogger fuse. Other common problems are the defogger switch itself or the switch not being plugged in properly, but there can also be a bad defogger relay, defective ETACM, or wiring issue. If you're capable of doing some electrical diagnosis, I'd encourage you to register for a free account at www.hmaservice.com (requires Internet Explorer and Adobe SVG Viewer) and print the schematic from the site. Also, does the indicator lamp come on when you depress the defogger button,I hope this help you in the right direction now you know how it works

93Toyota Corolla DX > Rear Defogger Inop


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.
