Why My Turn Signals Don't Work ~ Diagnosis

[@johntothejackson]

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

[@rishreinen5587]

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.

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...

[@johnhuffman9693]

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!

[@olenaerhardt7725]

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).

[@kencoggins3346]

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.

[@uncrunch398]

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.

[@bobbyboy1318]

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!

[@rudolfhuijs4526]

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! 😝

[@JD-xt8cj]

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...

[@Nipplator99999999999]

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.

[@Mr.M1STER]

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.

[@HumbleMechanic]

+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.

[@jhyde2129]

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.

[@adrian-gabrieldinescu4066]

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!

[@rudolfhuijs4526]

Great advice! I will try that tomorrow in my Passat. Thanks!

[@rudolfhuijs4526]

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.

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.

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.

What if you push up for your right turn signal which flashes but then your left turn signal starts flashing instead like its switching back n forth?

[@kittywong2450]

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.

[@scientist100]

I had come to see if there was a way to diag these kinds of vehicles. The one I'm dealing with is a newer car which works over com lines. What's weird in my case is that the turn lights work after a period of time; so this is what it does: 1. Turn signal on the right side: front right blinks normally for 2-3 times and then becomes solid, after around 10 seconds, it starts to blink normally but the flasher indicator on the cluster blinks rapidly even though that's not the case with the physical bult on the front right only, it does that throughout the whole time. 2. Same with the left turn side, except the bulb that is acting up is the right rear. Using the hazard button duplicates the same scenario for both lights; I'm starting to think that the BCM called Vehicle Electrical System Control Module is failing. Sets codes for open circuit / short to power in both cases, the monitoring system is not working properly; swapping the bulbs to the other side of the turn signal lights do not follow the fault either so the bulb cannot be the culprit. Just not sure why it fails like this and replicates the fault every time; I've never seen something like that before.

[@Waldo425]

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.

Wow, that harness looks gnarly. Makes you wonder if it would be better to make a fresh light harness for yourself and re-pin the connectors - if that's possible on these cars.

[@HumbleMechanic]

+aussiebloke609 it's possible. Doing that would probably be a little cheaper too. Luckily VW offers the harness separate. I had one in my tool box for some reason, and bought another one. So fixing this cost me about $40

[@aussiebloke609]

I'd hate to install something that was going to get so ratty again. I think I'd do the rewire, just so I didn't have to worry about it in the future - unless they've upgraded their insulation since. I've had cars that were left out in the Australian sun for 30 years, and the elec. insulation didn't get nearly as brittle and flaky as that.

[@KingZoneOne]

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.

[@mickjager5974]

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?

On my 96 Toyota Avalon my front blinkers work but my rear do not. The blinker blinks fast as if it knows the bulb is out. I replaced the bulbs, but still no luck any guesses?

Question- both turn signals are working but the hazard indicator button stopped working. If I turn on left signal and Hazard button together then the hazard light button and signal blanks. If i turn on the right signal and hazard button, the signal blanks but the hazard button does not. Any advice on where to check why the hazard is not working?

Hi Charles! Two questions from Brazil: Does the electronic central of a mk7 golf record an access log from a non VAS/VAG scanner? In USA if you use a ordinary scanner to check an error code in a VW car the dealer can cancel the guarantee of the vehicle? Thanks for your great videos!

+Paulo Ferro using a different scanner won't do anything to the warranty or guarantee. I am not sure exactly what you're asking on the first question. I think it will work just fine.

[@pauloferro138]

Many thanks for your prompt answer! The first question is related to an argument of the dealer in my city. The guy said that the ECM record any access of a different scanner than an official VW scanner and if this registry is known by the factory/dealer it cancel the vehicle guarantee. Thanks again!
