Why My Turn Signals Don't Work ~ Diagnosis
HTML-код
- Опубликовано: 16 май 2017
- The turn signals in my 2005 VW Passat do not work. Today we are going to diagnose why the signals failed, including the hazard relay, checking fuses, and separating the circuits.

There are many methods of diagnosing turn signals not working. This is just one method. I used this method because anyone can do it, and you don't really need any special diagnosis tools.

Hello HM, an excellent and thorough presentation for repair. I'm a mechanic myself and was looking on youtube for the diagnostics for a wiper switch for a 1997 Ford Ranger which has been giving me a headache. Your method of teaching is excellent, and though I didn't get anything dealing with my wiper switch, still, I learned your technique for solution of a short, and it is a good technique . . . excellent.
BMW drivers be like "What's a turn signal?"
erik myers lol or everyone I Utah !!!
BMW BIG MONEY WASTER
Youre suppose to know where they are going to turn
But what is it idk
Mine litterly dont even work
No questions today, just a thank you for taking the time to record and upload the knowledge
+Brad Nimbus thanks so much
hey Charles. I have lots of specialty tools in my tool arsenal. your videos/expertise is part of it. thanks for sharing your experience. I've wrenched for over 30 years professionally but in reality my whole life (49).a good tech never stops learning. if I ever get a chance, have a cold one on me.cheers mate.
Awesome video!! I had some issues with my 03 V6 b5.5 Passat where I replaced my relay, and even the turn signal wand and still had no signals for almost 6 months. Well, finally one day while my mechanic was replacing my steering wheel he realized these sort of connectors that we're placed DIRECTLY UNDER THE STEERING WHEEL AIRBAG COMPARTMENT. Once connected, I had turn signals again, even connected my old relay just to discover it still worked fine and I'm pretty sure my old turn signal wand still works too. But this was just in case anyone had the problem and these AWESOME VIDEOS LIKE THIS ONE didn't help...
YOURE A DANG GENIUS. SOON AS YOU SAID WARNING LIGHTS BEING CONNECTED. I PERKED UP, hit my warnings and signaled left and it came right on
Well done, Charles! You missed one critical diagnostic step, though: You forgot to check for a BMW badge on the trunk lid! ;D
+rhkips Hahahha it's true
rhkips haha...that is exactly what I was about to post
I have the same problem and was just going to replace the fuses and be done with it. Knowing that the headlights may be the cause of the fuses blowing saves me a great deal of time and money. Thanks.
Excellent video. Just bought a 95 wrangler. Turn signals don't work but the guy I bought it from had replaced headlights with LED. I think this video is the exact trouble shooting guide I needed! Will find out shortly. Thank you!
A great tutorial that is well articulated in layman terms.
Strong work Brother. 👍
Thank you for this video! I have figured that mine is a wiring issue and didn't have a clue as to where to begin looking. I will look inside the headlight to see if the problem is there. Thanks so much!
Perfect video that just focuses on the diagnoses which is really good. My issue was with the wiring. This video helped me realize that. Thanks
Glad to help
Great walk through. That wire insulation crumbling is unbelievable.
Thank you for the informative film. My Turn Signals stopped working, I did several things on it, so it was sitting for a while. What it was in my case:
I found it!! And what it was, I removed the headliner board for re[placing the upholstery on it, and disconnected the wire to the ceiling lens. The shop manual (I fortunately have for that car 2001 Saturn SL2) advised to attach those wires w/scotch tape, so I disconnected it fm/the plug by the rear window. The plug was sitting on a thin plate, which I assumed was there for keeping the plug in correct place. After I did some research I've learned that grounding could cause Turning Signals go off. The Manual showed 2 grounding wires on the rear close to that plug. There was a clip on the plug, metal one. I disconnected the grounding there, so even w/plug in the T S-ls didn't work of course. It might be helpful for someone else. Pls check the grounding as well if you have a problem w/T Signals and the fuse is fine. I was about to replace the Steering Column Switch, and actually ordered one already (so will have a spare now, not bad thing though).
just finished my basic electrical class today at UTI and this was really cool of you how you kept going to see the real problem of why they fuse melted. more electrical diag videos please :D
Hello friends! In case the turn signals don't work and the hazard lights do work, you can try and check the hazard lights relay situated inside the hazard light button. Reinforce the contact between the metal slips as they to tend to go apart after some usage. This was my case, after 100.000 miles, and the fix was easy (pull out the button and pry the metal slips closer). I am currently at 170.000 miles with the original button/relay! Safe driving!
Great advice! I will try that tomorrow in my Passat. Thanks!
Adrian thanks for the advice. Today I checked the turn signals fuse (10a) and it was blown. This was on fuse slot #2. Replaced, checked and it was good to go.
I must say I installed 2 years ago a turn signal LED dynamic strip. I guess the load is a little too much for that circuit, maybe upgrading to a 15a fuse will do. Will have to check amp load on that circuit.
Thanks anyway man for the advice.
@@rudolfhuijs4526 up
Here again Charles. I had the same issue on my Passat, turn signals not working, but hazard lights ok. Checked the fuse on #2 and it was blown. Have to mention I installed a pair of dynamic LED turn signals 2 years ago without cancelling the bulb (load) inside the headlight housing. For now it was replaved with a 10a fuse, but I should check the circuit's load. So there it is, sometimes we mod smthg and later it backfires. Kind of like that engine you destroyed with the nitrous! 😝
Charles finaly got to the problem with the turn signals, being eratic , it was the signal lever internal problems . unbeleivable ,thanks for your help .
Thanks lots of people have terrible things to say till it happens to them thank you for your time...
Hi, this is a very patient mechanic. And he doesnt shot gun a problem. Very cool
Thank you
Wow thank you man. This video help me to understand many things. Thank you very much.
Much appreciated for the video, I appreciate the help 🙏🙏 had no idea the two worked on the same relay
I own a 2003 V6 B5.5 Passat wagon that looks and runs like new, but only because I am obsessive with maintenance. I'm the original owner and I love it. I had no idea these headlight wires were so prone to cracking - good to know. They should have used wiring with silicone insulation or some other material if subject to that much heat. Had to replace the wiring from the ECU to the coil pack recently ... after 14 years of baking from engine heat they did started to do the same thing. PS - love the videos.
thank You..You made it simple for me....My hazards don't work nor the turn signals. I noticed my passenger head light was out of the socket.. I need to check it further...Thanks I will check the fuses again
Your advice was spot on! Now do a video on why overhead light not working! please. lol
Thanks to this video, I fixed my turn signals. While I was at it, the electric locks and seats. The fuse wasn't the problem for the flashers. It's something in the steering column. Adjusted all the way down, they don't work. Up a couple steps, perfect. I don't adjust it anymore.
Thanks for the diagnostic steps. Solved the problem for me, i.e., short in headlight from missing wire sheathing.
By far you are the best mechanic I have come across dealing with the VW/Audi manufacturers. Thanks
This freakin guy just solved my school bus light issue
0zzz
always trust the bearded guys! 😂
Thanks so much.saved me big money and time.
Had same issue..all wires bad inside headlite..
Thanks so much
I am currently editing the video(s) for removing the headlights and fixing the issue I found.
it's always seemed like voodoo to me, to figure out how to replace a wiring harness... I can never get my head around where the various harnesses run to, I'm afraid to start unwrapping things, etc...
JD when I was getting started learning electrical, when all plugs could interchange, i looped masking tape on both sides of connection plugs with something identical written on each before separation to easily identify mated plugs. I have noticed an increasing trend of all connectors are becoming unique. Another thing to remember is wires don't really deform after long-term placement and many hot/cold cycles so don't bind them in bundles and majority of harnesses will layout almost exactly with little effort. I wish you luck but after basics are learned the rest is mostly some knowledge and mostly applied common sense.
Humble mechanic.. Left turn signal turns of headlights.. Any idea why?
I have a similar problem with my jeep. Except that when I turn on the blinker, the dashboard light comes on and does not blink. And yet the hazard works fine. Any ideas?
I'm at a lost, was tighting my drivers side headlight and having a hard time putting the clip on 2006 bmw 325i, I made contact with the needle nose plyers and now my turn signals, wipers , bright lights all together not working
I love your way of working.
Thanks a lot for the video
This was exactly what happened with mine. Thanks
Man, cars are fascinating
Good job! Info is all good. Diagnostic is as important as fix!
Hi I’ve just come across your video along with others. Really helpful how to explain everything. Unfortunately I don’t think it will help me with my problem on my 2003 beetle. No indicators or hazards, all fuses good, replaced the hazard relay, after we did that, all indicators and hazards working fine, then 30 mins into driving the car, smoke coming out of relay switch and no indicators again 😕
This is a bulb shorting, replace all turn signal bulbs.
This reminded me of every cell tech call ever. " Did you try restarting the device". Yeah dude we've checked the fuse. Jesh
Thanks so much for sharing this,it's a great help
I hear you. Well I did the check on the hazard light and then went and loosened the headlights on each side and did the checks. My hazards came back on. Then the blinkers started to work again. Thank God. I didn't want to have to take it to my mechanic. I have a 96 Honda Accord LX. And I think the power steering fluid container is spraying out fluid on to the wires that go to the driver side head light. The whole area on that side is really oily. So I don't know. But the blinkers are back on.
Great video Charles, as always! ❤️👍
Great breakdown on how to find a issue.
+wyattoneable thank you
When I am checking fuses I always make sure to check them all like you do. I also like to study the fuses and the fuse card or owners manual, depending on the car, for fuses that should be in a certain place that may be missing. I have seen problem on cars before where nobody could figure it out and I would find a fuse missing altogether.
+Mr.Mister I've seen missing fuses burn techs so many times. To me, checking fuses also includes looking for missing ones.
I've seen guys spend days on cars over missing fuses.
HumbleMechanic Yep. Thanks for the reply, as always.
fuse removal tool, mind is blown!
This video was easy to understand and helpful. Thank you
Very Nice info! Logical and to the point. Good work! Thank you!
+Murphy Padgett thank you
Hi. MR Humble thank you for showing me to fixing the signals now is working thank you every much good video I will 👀 next time.
This is great, thanks! I am, oddly enough, working on my maroon 98 S10 and certainly this is the route I need to take. Both sides dead at same time, now to check fuses, and wiring. Could be grounds corrosion or wiring breaking I mean the thing is ancient at this point. lol. Parts cannon approach wants me to swap the signal tree in the column as it is a known issue, but the wipers, cruise control all work perfectly.
It is rarely just the fuse, so hopefully I can track this one down. 190 bucks is pretty steep for that unit so it will be worth it.
Did you ever find the issue? Having a similar problem with my 00 vette. Front signals don’t work. Changed the $300 column stick and nothing changed 😭
Great video, straight to the problem no joke
Great video! Now I have an idea of what to do!
just fixxed my car and the problem was just a fuse!! thanks a lot,,
Thank you for this video. For some reason mine doest work but does click by the fuse box. Then if you really push on the relay a certain way, it works. But I can't get it to work steady. I have replaced the relay
This is a great video. Thank you so much.
This was really helpful, thank you.
Your good buddy, explanation is clear.
I have this exact car but it’s up to 155 k miles. Only thing I had to replace was a hose that I got for $16 in Amazon. And now have to fix a fast right signal that’s probably a faulty bulb.
Always feel like I’m the luckiest VW owner from everyone’s stories
Djeezuss , that's really bad plastic... wow, never seen that ..
Thank you just worked out what my problem was
You are freaking amazing and just solved my crisis LOL
Thank you Sir.
For the effort, I appreciated on ur
Tutorial.
super fan of diagnosing videos
Thanks
Nice Phatbox ;)
I love mine.
Great mechanics are thorough mechanics like our expert here.
I had somewhat of the same problem My 2003 chevy venture would blow the back door automatic door open would blow the fuse. I used a 12 volt test light . I had a repair book for it and chased down the wire along the floor and found out it was caused by the factory had not put a waterproof system around the wire harness . I checked the other harness on the other side and it had the water proofing . I took it to a dealer and they had to fix it for free since it was a factory problem.
I have to thank you for this video. I have a 2003 Pontiac Sunbird, 115k. The turn signals and reverse lights had stopped working (they share a fuse on this car), and checked fuse, not tripped. replaced bulbs all the way around (Reverse now works), no luck on signals, BUT
...I did turn on hazards, and they all worked. (surprise me..duh) Here's the part that confuses me: the turn signals work, for now! What should I be looking at to prevent this problem in future? Wish I had thought to check hazards first, but lesson learned there...thus my thank you for the video..Any ideas on prevention?
I'm having issues with turn signals, thank you for the tutorial, I'm about to jump into the car and see if I can fix it today.
Good luck!
That 1.8t would really benefit from a GT28rs or at least a K04. :)
Hey, non-VW question (Audi) I upgraded all of my exterior bulbs to L.E.D.'s and I'm getting all
the expected bulb out faults at the dash. I was led to understand that
as an alternative to having multiple resistors for every replaced bulb
to remedy this, I could replace a specific turn indicator relay (not the
emergency flasher switch/button/relay) instead. Through all of my
searching both my car and the web, I am unable to locate any actual
information on a relay for the turn signals separate from the
emergency flasher switch, yet parts stores appear to sell them. I have a
2008 A4/B7 Quattro S-Line sedan. I need to know is there in
fact a separate relay from the emergency flashers for the turn indicator
lights? My turn signals hyper flash due to the L.E.D.'s, yet my hazards
do not, and function as normal.
gread video. Quuck question though, any idea why my indicators for low and high beam abd fog lights are not working when headlights are on
Excellent video. Thanks.
It's a common problem that the hazard/blinker relay unit fails, replace it and you are golden. ;D
+sucowar that's the most common issue for sure. But not he only one ;)
Good video , Charles ! A lot of people that watch your videos probably are not professional Tech's . I'am assuming . I know what bulb monitoring is but maybe some of your other views may not , maybe you could explain that in one of your pod cast's . Working on ford vehicles , this feature would have a message on the DIC .( Check left front turn signal bulb ). Or something like that . How does VW do this function . Ford uses (SJB) smart junction box.
Appreciate the information though. A lot of steps. To finding the fix.
That is sometimes how it goes. Most of the time it's a simple quick check, but others require more
Very informative, thank you.
Thank you
Hello i loved your video i have a 2006 dodge dakota that does kinda same as yours but mine emergency lights works perfectly but not thw signals lights.
My turn signals work sometimes but sometimes don't. Hazards work even when turn sigs don't. Fuses are good. Help
Hey humble mechanic I got a 1998 Audi A4 2.8 and my turn signal don’t work. Both the fuses are good. I had to put a turn signal switch in the car as it was damaged. Any ideas
It’s not issue I’m having but very helpful thanks
What sort of testing probe are you using...would like to get one. Thanks
After I changed both of my headlights on my Mitsubishi Galant 2007 , the turn signal stopped working. They checked the fuses but, all of them were good. So frustrating being without blinkers.
Happened to me today, knew what it was right away.
I had an intermittent problem with my right turn signal. It’d only happen if I took a hard right or hit a bump. I knew what I was looking for but the wire eluded me. I ended taking it to the dealer. The poor tech spent 8 hours to find it. He got paid for 1. Flat rate took his lunch that day and I feel validated in how hard it was but bad for the tech.
It's after midnight. I had a new radio put in my 2010 KIA Soul today at Best Buy. He told me the factory radio was toast. The new radio has GPS and it's really nice to have my music back. Tonight I noticed my directionals are not working. Oops! I'm going out to the alligator-infested parking lot here in Palm Springs, Fl and try to pull a fuse or two. Thanks for your great video. I can't get back to Best Buy until Wednesday. Off to Pompano Beach tomorrow to take delivery on a 2002 Cadillac Deville. I wonder if the dark cloud that always follows me will come along on the train ride?
Be safe!!!
Very well done.
what are your thoughts on having a set of circuit breakers that match the fuses for use in troubleshooting? at $13 each for the manual reset ones you could get a lot of fuses, but I think it would be good long-term and ensuring that when the replacement fuse goes in it won't blow
I’ve had an ongoing issue with my left side blinker whenever it rains. 2005 Passat TDI wagon. I’ve spent hours, techs have spent hours. Nobody can figure out where the fault is coming from because sometimes it shorts and sometimes it doesn’t. Got a 10 amp auto-reset fuse for the blinker slot and it’s a lifesaver because the damn thing was shorting so often I’d have to pull over and put in a new fuse on the expressway. Anyway....gonna check the headlights and see if that might be the issue. But I think the problem is likely in the side mirror shell. Wires got dried out and when there’s moisture present, they get all persnickety.
Great on the head light diagnostics I had the same problem on my 09 tiggy.
Now I have another issue that I'm asking for help with.
Every time I remove the oil cap the car almost stalls and runs terrible.
I'm thinking a pcv valv? What do you thinking?
Thanks for the help
+Jeriko A, Sosa that's normal. It makes a big vacuum leak.
If you took it off and the car ran good I'd be worried
Absolutely excellent!!
U helped me of just the picture thank u
Thanx man, I've been looking thru alot of these trying to figure out y only my right turn don't work and all I've been hearing is it's either fuse or flasher relay if not those the turn signal switch..I bought flashers and bulbs and seen the switch goes for $175 used and I would hate to pay that to find its not that,my main problem is the previous owner thought he was a master electrician,those wires are thrown on the starter fuse and the fuel pump moved to the horn fuse and radio wired into a non existent ac unit wiring...so im just looking for more wiring problems...lol
U find the issue? Mine works off and on too I heard it’s a known issue but I need the fix for it
Well, I have watched your vid again w/o realizing it. The guy I bought my 2001 Beetle from (lives 4 houses away and) has his own shop in town GermanWerks - yet he doesn't know how to fix many of the issues I am willing to pay to get resolved (which were present when I bought the little beast.) I should have figured it out by now (5 yrs later) he sold it because it became a hot mess and wanted to pass it off to someone - anyone - else. My dilemma is what to fix of the many issues just so I can pass it off to someone - anyone - else.
But on the positive side, everyone (it seems) young, old, male, female, gay, straight all look at my little buggy and smile. (prob not WWII Vets if still alive)
I think it's a great little ride, my skinny butt fits the seat but I don't think the transmission is going to last much longer, it's getting harder & harder to shift into reverse. And now...that's enough endless bother from me. If I have the little Black Jelly Bean (I HATE ANISE! - the flavor of black licorice) in another 4-5 yrs and find your site, I'm sure I'll have a new set of so sorry for me having to tolerate the little Black Beetle of which I have no trouble stepping on the insect any time of the day or night.
ur a good guy. Thank you.
Thank you
Fixed it with your thumbnail. Lol Thanks!
Hahahah
I have a 2003 ford focus. In summer when interior of car gets warm/hot turn signals don't work but hazards do. Also wipers don't work in intermittent or wash, but they do work in low or high. Both functions will start working again if the car interior gets cool enough, but can take till the next morning. I'm thinking it's timer/relay on what ford calls a GEM (generic or general electric module). Any similar issue with VW , other brand or worked on a ford?
@mossman381. Thanks for replying. My signal and flasher lights blink inside appearing ok, but rear right blinker not working after another new bulb. It did blink while hanging on the bumper. Right blinker blinks faster than other on the panel. I'm gonna refer your videos to mechanic and tell him to change hazard switch. I really think he gave it back to me not working. Thank you so much for the videos.
Thanks dude I rectify my Lexus is 250 by your vedio
My hazards work , when pressed the cluster lights up and flashers on the front and back on the vehicle work but when i use the turn signals nothing happens. No cluster lights and no exterior lights. Would I still replace the hazard relay? I have a 02 VW Jetta
So you altered the tip of that PP? I like it. Going to have to steal that one.
Steal on man. I love the bent tip. It's great for this set up. It is not so great for the newer fuse panels on VW
Did you become "bent" as a result of working on VW's for so many years?
Seriously, I like your approach to diagnosing vehicle ills. A professional and common sense approach to proper diagnosis.
Thank you, Nice Video.
i had a similar problem on my mk4 golf. the passenger side headlight wires were super bad and i had no interior lights
I have Kia Amanti 04 turn signals work hazards don't, I forced them on with the autel scanner and it worked. I checked fuses, wiring looks good but I don't have the connector end view to distinguish the wiring. So I don't know if it's the button itself or faulty wiring
