Golf IV / Jetta IV :: 3rd Brake Light Isn't Working?
Sep 30, 2015
I removed the rear shelf to do some reupholstering. Obviously, the third brake light is enclosed in this assy. Now every thing is back together and my 3rd brake light isn't working anymore. Probably got banged around when it was out. On troubleshooting it, it actually works but comes on so low that you can't even see it behind the glass. I even disassembled the whole thing and directly wired it to the car battery same results. All LEDs illuminate but at a fraction of what they should. I'd say maybe 1/10 of what they should. I checked continuity of the whole circuit board and every thing checks with no broken solder except for 1 diode. It's the black one on the far right that has no continuity. Why such a low illumination?

I just got a 2001 Jetta 2.0 (I know slow but I needed a work vehicle) and the dash lights and passenger rail lights don't work, the check engine light, fuel light, all those type of lights work, but the speedometer and blinkers and that stuff don't work, and then the blinker works in the back but no break light. I'm pretty good mechanically but when it comes to electrical stuff I'm completely stumped. What it could be? I haven't looked into anything due to just getting it last night and having to work this morning.

About a week ago I turned on the Climatronic a/c in my 99.5 GTI for the first time since I bought the car. Everything worked fine until a bug splattered my windshield. I sprayed washer fluid and the wiper moved extremely slowly to the halfway point and then stopped. The wipers have always moved slowly since I got it about 6 or 7k km ago but have never become stuck. I turned off the a/c and let the car sit for a while turned off. When I turned it on again, the wipers worked fine but the were noticeably slower then before.
Cut to a few days later, I turn on the wipers to test it out and it gets stuck again, this time about 3 inches from the bottom. I can hear them clicking as if they are restarting the cycle, but it only twitches.
Cut to now, the wipers try to move every time I turn the key to ACC, as well as twitching when the car starts. When I start driving, after approx. 2 minutes my ABS light comes on and doesn't go away until I shut off the car.
I have provided a video. This is my only car and there's rain coming up in the forecast ...

My brake fluid is fine and fuses 5 & 9 are good. Brake lever is all the way down as well. Have read that for some simply replacing the cap worked. Car is a 2000 w/170K. BTW, A/C does not work, clutch not spinning, fuses ok there as well. I've made sure a/c button is not on nor is recirc button. Some have said probe can be related to this but that also can show up with a bad fuse # 5, but mine is good.

So my brake light on my dash is on. The other morning when I started my car the like came on blinking with only 3 beeps. No more beeping after that just blinking. Now it has been doing this every time I start my car since (3 beeps and blinking). My abs light is also on but it has been on for years. I checked the brake fluid and it is full. I also never use my ebrake because it doesn't work so this shouldn't be the problem.

So yesterday on my way to work the EPC light came on. Everything seemed fine. No loss of power or check engine light. Just an EPC light on the dash. So after searching around and checking the forums I decided to step outside and check the codes. I have a bluetooth OBD2 deal that talks to my phone and I have software on my phone to read and clear codes and other things. I checked but no codes. So I decided to do the clear codes function and it made the EPC light go off. On my way to grab some lunch the EPC light came back on and I noticed my cruise control would not work. Did some more research and figured it must be the brake light switch.
Went and bought one for 15 bucks and installed it. Cleared the light again with my phone and headed home. On my way home the EPC light comes back on. Once I get home I check and find my brake lights dont work at all. I checked the switch and it is functioning properly. I could even unplug the brake light switch and jump the red/brown power wire to the red/black wire and they still wouldn't light up. No power getting back to the lights. This morning I get up and head to work. No more EPC light and my brake lights are working fine. I'm thinking maybe a short in that red/black wire but I just don't know. Does that wire go straight from the brake light switch to the brake lights or does it go through any modules or connectors or anything? I would love to get a schematic of the Brake light wiring. 2002 GTI VR6.

So my brake pads worn light came on recently on my 03 jetta...low and behold all 4 brake pads needed changing...funny though because upon buying pads with the sensor when I went to put new pads on the old ones didnt even have a sensor it was already cut at the harness and spliced together to keep the light off....so upon inspection one of the wires was black and the other copper....idk if one was supposed to be black or if its because its fried? Anyways i went as far up the wires as I could till they are harnessed in with the abs sensor wires...still one wire black....spliced together crimped and still the light comes and goes....I dont have access to the vcds or vagcom so can't turn it off that way..

So I noticed a few days ago just one of my license plate bulbs blew, so I tried throwing another in and it won't light up. If I check for 12v at the housing and I have 12 where do I go from there? 2005 golf 2.slow

So the 12V power outlet (the one up front by ashtray) in my MK4 Jetta is not working anymore. There was a penny stuck in there and my dumb friend tried ramming his phone charging in anyways and it sparked and now won't work even though I got the penny out. I already checked and replaced fuse 41 and it did not do anything or look blown. Now, the fuse area is looks pretty gross and I'm going to remove it and clean it, but do you think there's maybe a short or something to do with ground since it sparked like that?

I started the car one morning after it snowed. the red "BRAKE" light is constantly on and while the car is moving it beeps which is extremely annoying.. I have tried:
-Topping off brake fluid
- another ebrake sensor (under the center console)
- brake pads have plenty of meat on them

My 1.8T with auto trans is stuck in park. I've read that the likely culprit is the break light switch but before I order the part and install it I wanted to check what else it can be because it was working fine before I fixed some coil wires. Basically I unplugged the ECU and tested continuity from the coil connectors to the ecu connectors.
I found an issues, resolved it, plugged everything back in, fire the car up, turned it off, re-installed all the covers, etc. Then I repaired a broken wire in the trunk lid wiring that was broken. But when I went to back it out of my garage I couldn't get it out of park.
If it's just happened to go while doing all this other work then it's just a coincidence, but are there other things I can check based on the ignition work I've been doing?

So, I was attempting to install license plate lights rather impatiently in a parking lot the other night at my weekly meet. I pulled out the factory lights, put in the LEDs, reconnected them, turned them on and all systems were go. I shut the lights off and at that point went and screwed the license plate light housings back into place and went and turned the lights on again, and they were not working, at all. I then decided to reinstall the stock bulbs and check it out, and they were not working at all either. So I haven't gotten to dig too much on this at all, but the headlights and taillights still work so I know it isn't the switch.
Plans for Tomorrow: Pull the light housings back out, take photos of everything, make sure all electrical connections are clean and looking good, and then try to get to the bottom of it.

my right rear tail light is not working. I tested the tray on the left side and the brake light works, so the problem must be from the right connector or right wiring back somewhere.
any tips on how to find the problem from here?

Experienced problems with their right taillight, both brake and turn signal light stopped working. This occurs intermittently. I have replaced my rear license plate lights with error free leds .

I have a 2000 VW Jetta GL. A few weeks ago I noticed my charging light come on followed by abs and airbag lights. Which would mean that the alternator is not charging the battery. However I kept on driving and this light would go off. However when I hit a bump on the road this light goes off meaning that the battery is being charged by the alternator. I recently installed a sound system in the vehicle which worked without problems for a few weeks before I started having this problem. Since then I have changed the alternator, battery and taken out the sound system. I now have a 125 amp alternator instead of a 90 amp alternator. The charge light doesn't come on anymore after startup but the abs, airbag and emergency brake light with a beep is now occurring.

Had the 2003 Jetta in for inspection, and he said the rear brake caliper was gone. SO he replaced it.
Now in the morning when I leave for work, as I go up my steep driveway, the brake warning light comes on and beeps at me. Then it stops.
On the way home, as I come up the steep road to my driveway, the warning light comes on and beeps at me!
All other times and all other driving, it's fine.

When I look back into the rear view the top brake light isn't a solid light, it keeps blinking but sometimes it won't blink and just have a solid light. Also, my friend pointed out to me that both of my reverse lights arenot even coming on. I suspect a loose wire somewhere. Where should I look? Or something else?

I have a 03 GLI 24V VR6 6 speed and im having an issue with the brake light.. ive checked all the fuses and emergency brake sensor and they are all good, the issue is the brake light flashes 3 times then will stay on almost immediately and whenever it does the entire drive of the car changes.. without the light on the car runs fine but when it comes on its like the car goes to a limp mode and is leaning out on fuel.. it wont rev past 4k it falls on its face and basically jerks along until I get where I am going.. I've replaced ABS speed sensors, MAF, and front brakes and axles recently.. before this was an random issue that would come and go but now its almost every time and it makes it undriveable..
