- In this video I fix the no low beam headlight (day time running lights) condition in this Chevrolet Trailblazer. The low beam headlights weren't coming on. The high beam lights work perfectly. I discovered it was a pretty simple fix! Just needed to replace the Headlamp Driver Module (HDM) relay.

Turns out it was a pretty simple fix! Failblazer: Failure is always an option!
"Failure is always an option" lolol
Funny cuz it seems like a whole mess of things want to fail all at once in a family members' '04. Hoping to get it all fixed up if they ever let me! It really is a nice vehicle. And I used to be completely against SUVs.
OMG dude your are a lifesaver ! I have a 2005 TB and I did the swap ! BOOM it works ! Thanks a million ! 2:15
Thanks a lot Big Bro!!!
Thank you so much for this, fixed my 07 fail blazer.
Your constantly calling them failblazers but they are 16+ years old brother 😂
Thanks for sharing bro! You’re the man!
It could’ve cost me around $300 until I decided to watch the video and I literally fix it in 5 minutes for free. God bless you and you’r family
Thank you a million times over for your easy to understand video. My husband is disabled and I was beside myself with my low beam headlights not working. I went to Auto Zone, told the guy what I wanted and purchased the relay switch and now I have lights once again. You taught an "old lady" how to do a simple fix on my Trail Blazer and I can't thank you enough. Please keep posting "fixes" for Trail Blazers on You Tube - I'm a fan for sure!!!!
Huge thanks! I'm rolling at night again. My 06 EXT has nearly 190k and just keeps going! We all appreciate your videos that keep breathing new life into our vehicles!
Thank you for this video. We were having this problem with our Envoy. My son insisted it was something that was going to be expensive and would have to go into the shop. After watching this, I went out and to the car to check this. My son came out and insisted it wasn't this but I convinced him to humor me and check it out just the same. We didn't have a spare but switched the two around to see if that was the problem and sure enough it was. He is now out looking for the part. Thank you again, this video was real easy to follow and understand.
Thanks so much for the advice which turned out to be right on the money for the problem with my 2004 Trailblazer headlights. You saved me a lot of grief.
I'm adding my thanks and appreciation here, too. I have a 2008 Trailblazer and the low beams just went out tonight; thanks to you, I was able to obtain a relay at my nearby Autozone store and got it replaced incredibly fast. Thank you so much!
I was leaving at 4:30am to bring my mom to the hospital and when I cranked up, no headlights!🤬. Check those 10amp fuses and said wait, let me see what UA-cam has to say and your video popped up. Spot on and thank you 👍🏿 I've got fuses but no relays. Will be hitting up Auto zone to get a couple and then Amazon to get a Grab Bag full...lol. Thanks again, I got mom to the hospital right on time ✌🏾
Man you are my guy thanks so much. I got 2 mechanics that didn't no what to do until we ran across your channel. You really, helped a brother out.
Same issue with my 2004 Chevy TB. Switching the relays showed it was bad. Thank you sir!
I couldn't figure out why both of my headlights would just stop working at the same time. The relay! This video was just what I needed.
Thanks for filming and posting this. 👍
Thank you thank you thank you! My wife called me as she was leaving work from the hospital saying the low beams won’t come on. I eventually had her drive home with the high beams. I would have had no idea where to begin to fix the problem had it not been for your video. I turned to youtube and found your video first. What a God send for me! I can’t thank you enough!!!
Glad the video helped you!
I have a 2006 Isuzu Acender the Trailblazer clone. This just happened and your vid was spot on! I love my SUV, 315,000 miles and I towed a horse trailer for 7yrs with it, beast!
OMG ! I JUST REPLACED THE SINGLE LOW BEAM WIRE HARNESS AND BULBS, but same problem. Your video just directed me to check other things now for a possibility. Im learning as i go the hard way i guess. Thank u very much for this video.
Thanks so much for the video. Super easy fix, but I wouldn't have known where to start without this video. I swapped the relays, low beams worked, went to the auto parts store, and had it diagnosed and fixed all in about 30 minutes for $36. Really appreciate it, man.
Good deal!
Ya hice eso pero no me funciono q más podra ser. Gracias
I've replaced headlights, check fuses, check plugs. Your video fixed it. Thank you.
Glad it helped
Brilliant and illuminating video! I had checked the two fuses. They were good. I bought new #9006 bulbs. Put one in. Didn't work. Only then did I do a Google/UA-cam search. Lo and behold, it was the Headlamp Driver Module (HDM) relay. There are two identical relays right next to each other in my 2006 Chevy Traiblazer L6. I swapped them and the low beams started working. The other relay is for fan control. On my way to the auto parts store for a new HDM relay. In the old days, we never had solid state relays to complicate auto maintenance and repair.
Everytime I go to the junkyard I always grab a handful of fuses from the trucks. Those relays are ridiculously expensive so it's nice to have extras.
Yes, a very good idea to grab 'em up cheap at a junk yard!
Ooooooo thats a good idea!!! Going this weekend to the junkyard.
Ridiculously expensive? $30...
@@ArSpartan0103 yup, a regular 12v relay can be had for around $3...
I just bought a cateye and I'm having the exact same issue. Definitely going to check the relay. Thanks
Dude you just saved me a trip to the auto mechanic!
Thank you!
Thank you!
Thank you!
Thank you! Weird thing was when I swapped the relays to check it and then swapped them back the relay worked, lol. That damn truck, I love it!!
thank you so much it works for me, I just changed the relay today, and let's see if the problem continues
A million thank you's! You just helped me discover the reason my headlights weren't coming on. God the part, plugged it in a WALLA! Let there be lights. I could hug you. :)
2 minutes in, right as you said the 2002s have 2 relays you can swap and test out, I paused everything. I went outside and gave the headlights on the old trailblazer another try. Holy smokes!! It actually worked! I checked fuse 3,4,5&6 and didnt see any that were blown. All I could think of doing at that point was either trying my luck on youtube and or pulling a wiring diagram. And sir you came through Thank You!
advice was spot on. swapped the relays lights working. thank you
Wooooo!! Thank you bro, thanks for shaving this video with everyone. Helped me out a lot.
thank you so much this saved me so much time.. I already tried to replace the headlight switch itself I was about to start looking at the bulbs and then I came across this video
This just happened to me today and they blew me off at the AutoZone. I went back and said I want this. Boom! It worked.
Thanks for this!! And here I was thinking the relay switch was going to be an electrical connector. Just a fuse relay? Easy peasy!!
Thank you soooooo much. I watch your videos all the time. You always have great advice. Please keep up the good work. 🌞 May God bless you 🙏.
Thank you so much!
Thank you I went through checked so many fuses you solved my problem saved me a ticket driving to work ❤
Você resolveu meu problema com meu 05 trailblazer , aqui em Massachusetts obrigado
I just fixed my truck with your video. Thanks so much!!!
Got the perfect 2nd vehicle since I've owned my 05 TB... a tow truck! My mechanic drives it more than I do.
Thanks Fixed my problem. I put in a salvaged fuse box to fix a open connection causing stalling, and that relay was blown. Thank you so much
Thank you for the quick emergency repair I was able to do in the dark
Dube!!..your a God sent bro...just got yourself another subscriber...thanks big brother!!
I came home from work on my high beams tonight, I'll definitely be checking this out tomorrow, maybe make my dad shocked I know what the problem is haha.
@The Daninator
Appreciate this video I replaced the low beams bulbs for new ones and I knew it wasn’t the bulbs watched this video and figured out it was the relay!!
Thank you so much buddy you made my day I went to Vance auto in that’s what it was $31 I have headlights now thank you again so much Steve From Chesapeake Virginia
Thank you, saved me a big mechanic bill!!
Thank you sir for the detailed video you’re very understandable on your video keep it up I just bought me a 2006 Chevy trailblazer myself and I thought it was electrical issue and the thing that you just show me just saved me a world of hassle. Thank you for the video. Very detailed good way to go thank you if I did not check the relays like you did I would never of known that I guess is a common problem. They just save me about seven hours of work. Thank you.
Thanks for the advice sure enough switched relay and started working!! Off to get relay thank again!!
Great to hear!
Absolutely saved me some headaches. Ty
Thanks for the info for this. I have a 2008 Trailblazer, been solid for me so far. But damn, the price for that small little relay is outrageous. There basically free at the junkyard, get 3 and would easily have one that definetly works.
Failblazer! hahaha I laughed out loud on that one. Nice video too. Thanks,
That was the issue w the 07 I was working on. Thank you.
You da man Dan! Checked the bulbs ok, put a multimeter on the socket NG, checked the fuses ok, multimeter on the fuse block contacts ok. Was just about to dig into the dash to check / replace switch ... wait YT to the rescue !!! Advanced Auto Parts store $43 HDM relay ... fixed.
Yeah man, that's the fix! Sure wish I had seen this BEFORE going to buy two replacement bulbs, taking of the grill, installing them and finding out they still didn't work!! Oh well, I really have been pretty lucky with my '08...thanks again
Damn same thing happen to me I was like man I did all of that for non 😂
Thank you very much direct to the point and help me out tremendously good job good job❤
Thank you so much you help fix our Failblazer no low beams
Wow that's a nice 2009 trailblazer so I have the same type model mine is a 2007. Can't believe my headlight finally burnt out on the right side all these years later. That was an easy one to replace so I can see the one on the left side is definitely dimmer. That's the hard one to replace. Can't believe how nice his glasses on his light I was just buffing mine today made them look much better but not as good as his I'm thinking about taking some really fine sandpaper I have and sanding one area of it to see if it helps. The sandpapers for like sanding clear coat. One time I saw a 2009 trailblazer for sale pretty good price. Probably as good a shape as mine which is excellent condition. When I saw the mileage I was like no way. It had $225,000 mi on it and at the time my car only had 175,000 mi on it. So it's 2 years newer and 75,000 mi more. And I know I have replaced everything on my car. You know those two little empty holes down by the fog lights well I found a square halogen light that's just a little bit brighter than a fog light. And I installed them down there so when I'm going through fog I can flip a switch and turn them on wow it is great.
I like the check wallet thing! Very appropriate! :)
this worked perfect for my 2007 envoy thank you sooo much
Awesome 👍
Thanks for the video.. question, what if it's only ONE (passenger side, low beam) headlight that keeps randomly going out.. the bulb works because sometimes it randomly comes on for about ten seconds when I start the truck then goes back out shortly after...
2003 v8 trailblazer it’s definitely a failblazer but you saved the day thanks
This video just saved me so much trouble! Thanks!
thank you fixed my girls car quick
Great video. I’m surprised you call them failblazers but your family has 2.
Thanks. I have on 06 "FAILBLAZER" I hope this is the case. I don't want to replace the switch.
This worked for me also, thanks for the video and sharing the knowledge ✌
Great to hear!
I’ve a 2006 trailblazer, so I’m pretty sure it’s the same issue I’m having 🙂👍. Went and bought the relay as well. Thanks
Thanks for the video. Took care of the issue.
hats off to you, sir! I owe you a beer!
Thanks for that tip! That saved me alot of trouble.
Glad it helped!
Thank you . You helped me big time 🙏🙏
Thanks alot for video post....... went to auto parts store and got new relay..... problem solved ! Thx ! 👍
Thank you very much for the video, I was able to fix that same problem
Lmfao, check wallet light. Great video bro.
So after installing a new air conditioning system my low beam headlights would not work so I watched your video I took The highbeam relays and switched it with the low beam relay and my low beam started working but yet my highbeams still worked but when I switch them back the low beam will not work so how will it work for the highbeam but not the low beam?
Thank you..! Man thank goodness I didn't pay much for mine. I'm gonna fix it and be prepared for nickel and diming, or a for sale sign!
Omg. The "Check Wallet" light 🤣
Your video bailed me out today. Thank you.
Glad I could help
I have the same problem, thank you for this video.
Thank you so much, fixed my issue.
Thanks this helped me with my 05 🙏
Saved my ass I have a 2002 chevy trailblazer low beams went out switched relays working again
Thank you you fix my problem!👍
Worked like a charm. Thank you!!!!
Great to hear!
Hi✋
I bought 2002 Trailblazer Ext last month
Today i noticed my lights doesnt work - tommorow i will chceck fuses and i hope it gonna help
But i have another thing and i dont know how to solve this. Probably at the same time when lights broke, also rear section of air contidion starts blowing whenever i turn off the car ( and it blows about 1 minute ).
Is it another issue with A/C or maybe i accidentialy turned something?
Greatings from Poland! :)
Great Job Young man!!!
Love how ya call em a fail blazer lol
Thank you so much for your help I greatly appreciate it 🙏 God bless
Excellent video!
Both my high and low went out on the way home. But then they all came back on. Does that relay control both? We just had a freeze. I wondered if that would cause it.
It work the relay switch was
Exactly 31.07 thank you 😊
Are bulbs a separate problem from fuses and relay fuse? I could have an issue with the switch itself like you’ve mentioned but how would I find the exact issue without spending money on the wrong purchase and without going to a mechanic? If that’s a thing.
Daninator you have been a godsend for me when dealing with the wife’s failblazer.
Glad the vids have been helpful!
Good stuff. I have the same problem (no low beams) on my daughter in-law's '13 GMC Terrain. I'm hoping it's just a faulty relay. We'll see. Thanks for the tip. I'll check that first.
Thanks from one Dan to another, spot on problem!
Got a 2007 Chevy trailblazer replace the two fuses for the low beams which a package of them cost about five bucks and brought the relay it was under forty dollars . Quick fix then decide to replace all of the ten amp fuses I had them
Thanks you saved me a ton of money.
Hey do these tb’s normally rev high on the freeway? I’m at about 23-25k rpm at 65mph 😬
I have an 07 TB. Over the past few weeks my low beams would just go off while driving down the road at night. Kinda scary in some dark areas of town. It seems pretty random, but I have noticed that the lights seem to get a little dimmer before going out. I don't think the light sensor up on the dash has ever worked. The low beam headlights only come on when shifting out of Park, or in the manual on position. Always have low beams at beginning of trip though. I rarely notice the lights during the daytime. Will checkout AZ and AAP later when they open to get a new relay
You just saved my life thank you
Thank you , your advice saved me money
Replaced both relays. Headlights work, but now check engine light on. Any suggestions? Check engine light was not on before i replaced the relays.
TY i was about to change out the entire switch
Part #15016745 they say it does not fit Trailblazer 2008 !?? Anyway, I order it in Amazon. Meanwhile, I tapped it on garage floor a few times, put it back : I have both low beam again.
Have the same problem with a '07 Equinox LS FWD. All lights work except lo beams. GM decided that permanent relays on the fuse block circuit board was a good idea. $200 bucks to replace.
My question is (besides why) with this set up how could a DYI diagnose this w/o paying a mechanic? Thanks...
