The camera work, the running commentary, the inset schematic with highlighting, the completeness of the vid -- probably the best I've seen period! THANK YOU for such an EXCELLENT tool!
Excellent troubleshooting! This is what separates the men from the boys in our field of work. I've seen alot of "shooting from the hip" and parts changers over the years. Well done!
You caught me thinking the question as to why you used a test light to check ground when you could have used a DVOM. Your next sentence showed the voltage drop under the load of your test light, and I felt a little sheepish. I probably would have missed that, and spent hours trying to figure it out. What's the point of that diode anyway?
Awesome video. Really hard to find anything about mid ninety's chevy DRL diag. Which is odd because there are usually several choices to pick from with a OBS
Can you please help me find this part on my Chevy Express Van 1500, 2001? They have been flickering and buzzing and now they don't work but affect my dash and starting ability. I'd like to remove the diode and bench test or just leave it out to see it it changes the behavior.
I been working on my 96 Hoe for sometime now and it is almost impossible to find good video references to repair her, your Videos are FANTASTIC! Thank you for doing such a great job!
So what happens if the relay ground is no good? Where do I look from there? I have DRLs but no low beams with swith on. Have high beams, just no low beams. I have replaced the brake light swith, turn signal switch and headlight switch and DRL relay. Checked for continuity at diode. But the ground side of the relay is no good.
Installed sylvania leds and new sockets in my 02 suburban, having trouble "seeing" then light as the parking brake kills them. Idea to just set car up so they light/or not? THX
I love this video and your direction on it. How you provide the wire diagram and explain what you're doing and thinking and following along with everything on the diagram.
I have a 2000 GMC Savana 3500. The rear running lights won’t stay on for some reason. I hear a loud click then they turn on then I hear a loud click again and they turn off? Any ideas on what it might be guys? Ground? If it was a fuse the rear running lights probably would work intermittently. ?
Excellent, thank you, my wife was experiencing DRL warning lamp on and sliding doors not opening in her Honda Odyssey (youngest daughter jumped into the driver's seat as my wife was filling up with gas). Seeing in this video that there is connection from DRL to parking brake, I suggested to her to see if the parking brake was accidentally on a bit. That fixed the problem...nothing like diagnosing car problems from work over the phone =).
Hello..thanks for your detailed video here but I am a bit slow with electronics..I have a 93 suburban and am removing the OWL headlights and replacing them with old school round headlights..I don't want the daytime lights..hpw can I wire it so that just the parking lights come on when I flip the top rocker switch...also there is already a problem because sometimes the DRL and parking lights do not even work..I think it's in the switch because if I turn them off and on they will work again...thanks again
GREAT video. I have a problem with dim lights at night but haven't started diagnostics yet. This video gave me a lot of info that I'm sure will be useful if my DRL goes out. Sure would like to see a video on diagnostics of dim HB & LB lights at night. My truck is a 1998 GMC Sierra but I've seen a lot of GMC/Chevy trucks running down the road at night with lights that so dim I'm sure they are like me......LOOK out for that deer!!!!!!
Just watched this video got a problem I can’t figure out 1999 GMC suburban K1500 5.7 v8 just all of sudden my headlights won’t come on new multi function switch new headlight switch running lights all work signal lights work brake lights work just no headlights low or high beams new DRL relay to what can I do
Have a 1996 3500. Low beams stay on until emergency brake switch is closed. Two black wires have great ground off daytime running lamp module. Could the module be defective?
Great video Ty I have a2003 Chevy Tahoe and one day the parking lights came on by themselves and I can’t turn them off in less pull the fuses for the taillights or unhook the ground on the battery would you have any idea what might cause this? Thank you in advance.
Hey I really like your videos I have a 1998 GMC Sierra having problems with a headlights when I click the high beams on no lights coming on but relay down on the floor next to the turn signal flasher relay buzzes
Can you use a jumper on the diode connector for emergency purposes? I have 97 gmc and the diode went bad, but I live in Costa Rica and can't find a replacement anywhere down here.
I have a 2000 Oldsmobile intrigue, the chime will not stop repeatedly dinging when in reverse or drive. Yesterday installed new passenger side headlight and daytime running lights stopped working then but no dinging at all yesterday. This morning the chime starts and will not stop if in reverse or drive. Please help what the fuck do I do?? This is sooooooo annoying
I would like to see if somebody has run into these problems is to parking light staying on on a 1999 Ford Windstar 3.8 l a s a l my friend disconnect the switch stays on the only way they come off is by turning taking a battery cable off I've been accounted for a lot of years but I haven't been able to figure this one out plus I don't have the van here please in Florida he's an older gentleman I would like to give him a hand if anybody can give me a about a cool appreciate it
i have a 97 regal and the passenger side daytime running light is off and the blinker doesn't work correctly on that same side... on the rear of passenger it blinks fast.. and i have a parasitic drain on the battery just after a couple hours.. could this be related to my issue ? or a way to fix my issue?oh and the first and third digit of the mileage is not showing either x2x863
Grateful to have come across these videos. I was able to diagnose, isolate and repair my non functional drl thanks to your walkthrough it's schematic. It is troubleshooting like this that not only separates the skilled from the novices but also teaches those with the desire and need to learn about their systems.
old video but really good one . recently i had one light burn out and so i decided to replace both DTL sockets and i did and know i have no power to either socket . i thought i soldered the wire reversed . DTL fuse under hood checked out good . not sure how i lost power
My fog lights work I was just messing around with my tail lights was about to change them but didn’t not my drl is not working what do you think it could be?
thanks i appreciate the compliment,I love the challenge that comes with electrical troubleshooting, I like to think its one of my specialty's, i enjoy it... so as long as you guys enjoy the vids i will continue, thanks again
I got a 97 Chevy Silverado and my passenger side head light runs demer then the driver side where's is the ground wire at Please help I will greatly appreciate it
We did removed the drl module to thinking it would fix our issue. The lights turn on on the switch but when I place the car in start position they won't come on....My Dad seems to think it's has something to do with the brake switch but we can not figure out how to bypass the emergency brake. Any help would be great!
Thank you very much for the compliment :) glad the time of editing didn't go unnoticed... these circuits can get pretty tricky. understanding and reviewing the schematic is crucial My hope is some will study this and have a better understanding like you mentioned... you may be on the right track with the guess, im heading to the shop shortly if i have some time i would like look into the noise. thanks again,
On my 2002 Silverado I'm installing all LED bulbs in the truck. I upgraded the stock flasher relay module under the dash with a new one to keep the LED's from hyper flashing. So today on the driver left side I put in the new turn signal LED bulbs with resistors for the higher lumen 3157 flashing rear bulb, and one 3157 bulb for the front. As well one front side mini flashing LED bulb that is lower lumens without a resistor. This was on the left/driver side of my truck. When I tested the left side, the turn signal in the back and both front signals were flashing. Then the mini flashing LED bulb stopped working. So I swapped it with a different mini LED bulb, and nothing, no flashing. I even tried a resistor on it, and nothing So I took the resistor and mini LED out of the left light socket and put back in the stock incandescent bulb, and it still wouldn't work. Now what is happening is the front 3157 & back 3157 largef turn signal bulbs that should flash. They just stay illuminated even though the left turn signal is not turned on. What could this be, because at first the front mini LED flashing turn signal along with the two 3157 bulbs front and back were all flashing fine. With that said before I installed all the bulbs, I did clean all the light bulb sockets with fast drying electrical spray/protectant. Though non of the other LED light bulbs had a problem. I thought about buying and splicing new mini light bulb sockets on the front. Then it got dark so I couldn't do anything else. And I don't believe it's a blown fuse or the front and back turn indicators wouldn't just stay illuminated. I'm totally stumped on what to do, could you please help me, thank you. ~Carl
I fixed it, you have to pay careful attention to which direction you put the upgraded LED Bulbs and relays in the turn light indicator sockets. Boy it was time consuming!!!
I did not think this would help me until I got to the part where you describe the Diode. Then it hit me!!! The 2002 Chev ZR2 Tracker Diagram I have from web shows a Diode!!! I could not make out the printed symbol (very small on screen and lettering tiny). Now I know. It has to be the Diode because the voltage issue is the same---reduced power. My problem is the interior lights have failed. Now all I have is the challenge of finding the Diode in the vehicle. Thanks much for the detail.
Hi I see the video in the one I'm working it doesn't have 86 86 the ground like you say I tried to figure out this one for my my dad becos he's got kidney disease and I don't know where is the all the grounds I hope you can read it thank you for the video
I'd like to see that device in action -- good idea. The only negative is the fact you need to be careful regarding what voltage gets sent where, though in this case the risks are small.
rtoledo2002 Exactly! Problem solving as a general skill is not common knowledge to most. And it is not being taught to the public in any significant magnitude that I am aware of! You just don’t know how much you don’t know, so understanding that is critical. A drawing or other technical document gets you closer to a solution. Even if you don’t understand what something is or what it does, at least you know now those things are present and should be tested or accounted for. There is much freedom to be found with the recognition of “I don’t know” if answers/information is then sought out. This builds confidence and self worth/value and empowers the individual to grow more... ♾💡🌈
:) many many times this misleads people including myself... Most DC live testing I Perform with a test light (With a bulb) just for that reason. An LED test light would show ok and can mislead as well. i should state some circuits are sensitive, so care needs to be taking while using a test light. i should cover that in a future video ... not 100% certain, will look into it though thanks again always look forward to your feedback
lol glad i could make your day a little better, thank you. That fancy test light is what came out of one of those Saturdays i had nothing better to do lol so i made a stubby test light with a needle point, that was over 5yrs ago one of the best tools in my box ;)
Everybody wants theirs off... I want to get mine running. Where is this diode for my 2000 Astro Van? It's not where you located yours. I thought I had it fixed... but nope. I DID fix the high speed blower though.
I have a 2001 chevy suburban 5.3 the driver side low beam light won't come on. The build works and i changed the fuse/dimmer switch. Also when I click ghe high beams, the passenger side won't come on..STUCK
Mine won't go out. I have a leak around some glass somewhere and water is getting into the car. When it get's hot there's condensation everywhere. I'm thinking the moisture may likely be the problem. Yeah. I know I have to take care of the water issue, but in the mean time I need to figure out why the headlights won't go off. And realistically, it may not be the day runners. I know I have heard what sounds like a relay trying to switch back and forth and the lights flicker when it does. My first try is to replace the headlight relay which is what brought me here looking for the location of the relay.
Hi I have 2003 z71 Chevy Tahoe and the chmsl does not work. I purchase a new one and it still does not work. the regular brakes are working fine. I did notice when I press the break power supply ends (found that with a tester) Just wondring if yo have any thoughts on that? thanks
I have no rear lights or interior lights when my headlights are on. Brake, signal and 4 ways are fine. After checking the fuses I discovered #15 was burnt. I put a new one in and checked the lights again and they still didn't work. I re checked the new fuse and it was burnt too???
hey rob i have a prob with my 2000 blazer when i over ride my driving lights my over head driver information center shuts off is that supposed to do that or no
1996 chevy silverado 1500 truck -- headlights are not working. so we change the headlight switch, headlight relay, head light diode. and still don't work . but the daytime running and hi beam works. what is our next thing to change or fix?
90% of your tests at the relay...amen brother, haha. This is the reason why I love relays, because at the relay, you can quickly determine...1. how the coil is controlled(ground side switched or power side switched) 2. Bypassing the load terminals(if the circuit now works) you just ruled out the entire load side of the circuit. 3. Current draw can be measure there(load side) and so many other awesome tests, mostly with inexpensive tools anyone can purchase at Sears or some ma and pa hardware store. The fact that your test light was nice and bright at fuse 15 but was dim at the relay is an instant red flag. Obviously there is a voltage drop problem and that problem is between the fuse and the relay, in this case, the diode. Love the work Will, keep it up.
Very very good demonstration. I have been struggling with this very problem on my 2000 Sierra 1500. It started as intermittent but is now chronic. What schematic software are you using? And how can the Ambient Light Sensor be tested ?
hi I have a 2005 nissan x-trail after driving for a while the left drl goes off in the same time the right drl goes on hb these don't change antil turning off the car for while. Any help thanks
I have a 05 chevy avalanche a d both turn signals work. Both brake lights work. And both reverse lights work. But the day time running light/night running rear lights on the left side will not turn on..... I am baffled.
I really enjoyed this video. You have explained everything very well for me to understand. I do not have the exact same problem, but I think it will help me solve my problem. I have one question: If the DRL Relay is not working could it disable Daytime Running Lamps & Low Beams? At the 3:40 mark in your video you said if the headlight switch is on that there is no need for the DRL Module to be working. From the wiring diagram the Lamp Feed travels to Head Lamp Dimmer Switch to the DRL Relay to the Low Beams. If the wires are good and no ground outs, are the two suspect faults the Head Lamp Dimmer Switch and the DRL Relay? Or just the Head Lamp Dimmer Switch? I have a '98 Chevy K1500 with no DRL or Low Beam. High Beams work. Checked fuse 4 & fuse 15. I'm checking the DRL Relay in the morning. I hope it is not the HLD switch. Relays are easy access to replace and less expensive. Thanks again for posting the video!
Great video. I am curious what the symptoms were that turned out to be a faulty diode? What was not working properly on the truck before the resolution? On my suburban, the daytime headlights work fine during the day. At night when I turn on the light switch, the instrument lights do not turn on, nor to the rear running lights. Weeks ago I checked fuse 15, but until I watched your video, I did not know to also check fuse, which I will do asap. Based on my symptoms do you suspect the DRL circuit ... If not, what should I check first, the diode? Your video is one of the best I have seen. Thanks so much.
i just wanted to say thank you for your videos on the day time running lights You help me narrow mine down to the relay switch and now my low beams work again. thank you agin.
hi i have a question, it is on 2004 sub my head lights are on all the time and the driver side running lights the passager side is not the amber light on the passager side worked till pulled the bulb out i put a new one in still does not work thanks
great job i have a truck 96 gmc i just put a head light swicth in now i dont have running lights or brake lights n blinkers in the back of truck but have power to the harness i cheak the fuses all good n the bulbs r good im lost now

I have the same problem,how do we fix it?
My 2002 gmc savana had no headlight left except through the DRL! Replaced every bulb, fuse, switch, etc….

I don't have a good ground on my DRL relay at terminal 86,where does that ground originate from?Thanks for your great videos.
Thank you, im going to check that out Looks like a great setup. Part 2 will be up soon
I'm checking fuses . I see what you mean with the numbers. Fuses good , my hdlp- hi is out. Lights in front but not in rear . Daytime running lights

Ambient light sensor working backwards! Where should I start looking?
best diagnostic video ever how do you get the wire schematic to highlight, some sort of program?
Gm...I had this issue and managed to get one light to come on...the other still hasn't came on...why has 1 came on and not the other?
do you have a Video of when you turn your lights and turn right it makes all my lights blink in the front any ideas ?

i have question my patriot jeep 2015 my headlight turned on by itself when engine not working every haft on hour
Did you make the part 2 video? I am trying to locate the module.
On my 2002 Silverado I'm installing all LED bulbs in the truck.

With that said before I installed all the bulbs, I did clean all the light bulb sockets with fast drying electrical spray/protectant. Though non of the other LED light bulbs had a problem.
I thought about buying and splicing new mini light bulb sockets on the front. Then it got dark so I couldn't do anything else. And I don't believe it's a blown fuse or the front and back turn indicators wouldn't just stay illuminated.
I'm totally stumped on what to do, could you please help me, thank you.

I fixed it, you have to pay careful attention to which direction you put the upgraded LED Bulbs and relays in the turn light indicator sockets.

Nice. The parking brake had fallen just enough to light the indicators. Pulled it up and the DRL is back in business. Thanks!
Mine won't go out. I have a leak around some glass somewhere and water is getting into the car. When it get's hot there's condensation everywhere. I'm thinking the moisture may likely be the problem. Yeah. I know I have to take care of the water issue, but in the mean time I need to figure out why the headlights won't go off. And realistically, it may not be the day runners. I know I have heard what sounds like a relay trying to switch back and forth and the lights flicker when it does. My first try is to replace the headlight relay which is what brought me here looking for the location of the relay.
Hi I have 2003 z71 Chevy Tahoe and the chmsl does not work. I purchase a new one and it still does not work. the regular brakes are working fine. I did notice when I press the break power supply ends (found that with a tester) Just wondring if yo have any thoughts on that?
thanks
I have no rear lights or interior lights when my headlights are on. Brake, signal and 4 ways are fine. After checking the fuses I discovered #15 was burnt. I put a new one in and checked the lights again and they still didn't work. I re checked the new fuse and it was burnt too???
Okay I have a silverado 05 my day time lights don't work. The only time they do work is when ever I activate my truck alarm , any suggestions thanks
hey rob i have a prob with my 2000 blazer when i over ride my driving lights my over head driver information center shuts off is that supposed to do that or no
Is this the same set up for a 95 suburban
1996 chevy silverado 1500 truck -- headlights are not working. so we change the headlight switch, headlight relay, head light diode. and still don't work . but the daytime running and hi beam works. what is our next thing to change or fix?
90% of your tests at the relay...amen brother, haha. This is the reason why I love relays, because at the relay, you can quickly determine...1. how the coil is controlled(ground side switched or power side switched) 2. Bypassing the load terminals(if the circuit now works) you just ruled out the entire load side of the circuit. 3. Current draw can be measure there(load side) and so many other awesome tests, mostly with inexpensive tools anyone can purchase at Sears or some ma and pa hardware store. The fact that your test light was nice and bright at fuse 15 but was dim at the relay is an instant red flag. Obviously there is a voltage drop problem and that problem is between the fuse and the relay, in this case, the diode. Love the work Will, keep it up.
Superior knowledge of the vehicle´s circuits only comes from a full understanding of electricity, and that´s what I found in your video. Thanks
where do you get your interactive wire diagrams?
Very very good demonstration. I have been struggling with this very problem on my 2000 Sierra 1500. It started as intermittent but is now chronic. What schematic software are you using? And how can the Ambient Light Sensor be tested ?
hi I have a 2005 nissan x-trail after driving for a while the left drl goes off in the same time the right drl goes on hb these don't change antil turning off the car for while. Any help thanks
I have a 05 chevy avalanche a d both turn signals work. Both brake lights work. And both reverse lights work. But the day time running light/night running rear lights on the left side will not turn on..... I am baffled.
I really enjoyed this video. You have explained everything very well for me to understand. I do not have the exact same problem, but I think it will help me solve my problem.
I have one question: If the DRL Relay is not working could it disable Daytime Running Lamps & Low Beams?
At the 3:40 mark in your video you said if the headlight switch is on that there is no need for the DRL Module to be working. From the wiring diagram the Lamp Feed travels to Head Lamp Dimmer Switch to the DRL Relay to the Low Beams.
If the wires are good and no ground outs, are the two suspect faults the Head Lamp Dimmer Switch and the DRL Relay? Or just the Head Lamp Dimmer Switch?
I have a '98 Chevy K1500 with no DRL or Low Beam. High Beams work. Checked fuse 4 & fuse 15. I'm checking the DRL Relay in the morning. I hope it is not the HLD switch. Relays are easy access to replace and less expensive.
Thanks again for posting the video!
I have a 07 impala with no drl just on the passenger side. Why? Turn signal work brake light works all around...just no drl on pass. Side
Great tutorial on auto electric troubleshooting. Clear and simple, like everything should be. I have tried this website but have message as FORBIDDEN
If I just remove the relay will the drl turn off? I’ve already taking the module out and they’re back on some how lol
Great video. I am curious what the symptoms were that turned out to be a faulty diode? What was not working properly on the truck before the resolution? On my suburban, the daytime headlights work fine during the day. At night when I turn on the light switch, the instrument lights do not turn on, nor to the rear running lights. Weeks ago I checked fuse 15, but until I watched your video, I did not know to also check fuse, which I will do asap. Based on my symptoms do you suspect the DRL circuit ... If not, what should I check first, the diode? Your video is one of the best I have seen. Thanks so much.
i just wanted to say thank you for your videos on the day time running lights You help me narrow mine down to the relay switch and now my low beams work again. thank you agin.
I have 99 yukon Denali I have no power to fuse 15 but fuse 4 has power lights work by switch cause I removed module, why does 15 have no power
Were do you get those schematics?
excellent information, I have a 2011 GMC Sierra, and will remember this video if/when my daytime running lights are problematic...thank you...
Man my lights just stopped working in caddlic don't have tools to check things like you do
Man your awesome!!!!! I have been trying to fix this for days until I watched your very easy to follow video. Thanks sooooooo much!!!👍👍
Where is the drl module located on a 2000 Ford Focus SE? I have high beams and fog lights but no low beam or daytime running lights?
hi i have a question, it is on 2004 sub my head lights are on all the time and the driver side running lights the passager side is
not the amber light on the passager side worked till pulled the bulb out i put a new one in still does not work
thanks
Funny, Most driver are disconnecting Daytime Running Lights (less tickets and better MPG).
do you know where the drl module is on a 2000 silverado 2500?? you seem to be the only person that has any kind of since on here... thanks.
Todd
Excellent video!!! Now I will apply my new found knowledge and see if I can solve my DRL problem. Thank you so much!
great job i have a truck 96 gmc i just put a head light swicth in now i dont have running lights or brake lights n blinkers in the back of truck but have power to the harness i cheak the fuses all good n the bulbs r good im lost now
I am having trouble with mines DRL in my 2010 toyota corolla they won't turn on could you help me out
