2002 wrangler gauges going out when i depress defrost switch

2002 TJ
one foggy windowed day i press the rear defrost rocker switch to turn it on, and my dome light came on, my gauges went dead, and as soon as i let go of the switch, everything is back to normal, but no defrost. when im holding the button down, it will defrost, but im not gonna drive around in a stick shift during michigan winter trying to steer, shift, not hit semis, and hold down a little button to see out my back window.

I had a new radio put in by best buy. And had an aftermarket before this new one, but it worked just fine with that radio, and the wiring should not have changed with my new one. especially since i have used the top before with the new radio with no problems.

That definitely sounds like a short. If this started happening after the radio was installed, more likely than not, it's because they either spliced into the wrong wire or they nicked or cut the wire insulation, causing the short. You can look for yourself, just start at the defroster switch, and trace the wiring as far as you can go. Then do the same for the radio wiring. Somewhere along the line, you'll find the problem. Or take it back to Best Buy and make them fix the problem. I would advise caution on that though, as they can install a stereo, but that doesnt make them experts on automotive wiring. Best bet if you dont want to do it yourself, take the Jeep to a good garage or a dealer, have them find the problem, and if it turns out Best Buy caused it, take the bill for the repair and let them pay it.

Defrost on my 2002 Cavalier will not work properly. Will melt ice off windows in the winter, but the side windows stay foggy unless I crack open a window.


your car's interior is wet-damp and is not being allowed to evaporate. Leave your windows cracked open in the garage a few day...and/or dry out the carpet or mats with a heater-blower.

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.

No more brake lights on my 2000 TJ,is there a fuse for rear brake lights?


Yes, there are 2 actually. One located inside the vehicle and one located under the hood. This could also be the brake switch located on the pedal. Check for a break in the wires on both light units especially if you have been four wheeling.
