It's always a good idea to check brake regularly. No surprises are the best surprises. Having a nice shop makes all the difference. Have a great week.
I complain about this heat but with concrete below me and a fan blowing on me all is well.
Sir you just saved me another prescription for antidepressants.
That's a great comment. Thank you.
I've pressed breaks with 2x4s, logs, bricks, and everything else under the sun. I have a reversing clamp like that! That's genius and I'm definitely stealing the idea!
Showing you a tip you haven't already thought of is amazing. I'm glad I showed the clamp idea now. It's cool when you know you did something that others can use or learn from.
Excellent find Wyatt. Sometimes electrical problems make me feel like a first year rookie.
Thanks for sharing
Oh yeah I struggle but with the help of scannerdanner, Eric, Ivan, Keith and a lot of others I'm getting more comfortable.
@@wyattoneable love them guy's.
Tracing it down can be a headache, glad you found it and was able to fix it...another one checked off the list. Y'all take care and God Bless!
Yes indeed. This truck needs a lot of attention. I have been neglectful but I'm catching up now. :) Thank you again for being here.
Great diagnosis and repair! Thanks for sharing! 😃👍
Your up early!
Good job of finding the problem. You looked at the wiring diagram, and kept it simple. Must people would have tried a reply without performing inspection and testing. I call them "Parts Bangers"
I was glad i had some clues do to troubleshooting plus a cruise control that worked intermediately. By getting the wiring diagram I could see that connector had wires going to the brake lights and the cruise control...bingo! Thanks Dave.
i love me some wiring issues! i am a solder, deox and heat shrink guy also....never have another problem at those connections. nice repair. always enjoy seeing another video from you.
They should last longer than I do. Thank you for spending some time here.
Thank you for the sleeping music I was having a hard time you did the trick thanks
Very nicely done Wyatt. Thanks for sharing 👍
Hi Dylan, nice to see you hear. I appreciate the comment.
Test light for the win! Nicely done Wyatt!
I love that tool. So easy and straightforward on simple circuits. Thanks for the comment.
That's a slick trick of keeping the pedal pushed down Wyatt 👍 and another job well done 😉
Thank you for the comment buddy.
Hey Wyatt, thanks for the video. Electrical business is a weak point for me but I learned something today. Have a good weekend.
Glad you enjoyed it Wally.
Fantastic use of the scientific method and diagrams!
DE, nice that you are watched and commented. I appreciate that.
Getting under the dashboard is the hardest part of that job. Nice diagnoses and repair.
I appreciate you friend.
Great find Wyatt and good that you could get a connector prewired. 😀👍
I was surprised the connector was available too. I was hoping the whole assembly was available but no such luck. Thanks for being here Terry.
Top notch / quality repair!
I'll never be as good as you but if I can keep this old truck going I'll be happy.
Thank you for taking the time to make this video sir. Hope I have luck fixing mine
Thank you for the comment and I hope you find a fix!
Wow! That was a tight job but it looks like you went straight to the issue! Nothing like finding out problems through the process fixing other things, like in this case, the lack of braking on the trailer. Very logical diag! Thanks for sharing Wyatt!! 🤗🤗😊😊
Tight fit and I'm not a small man. :) I found the problem pretty quickly but getting to it was another story. Thank you for the kind words.
Nice diagnosis Dave. Sure to help some folks!
Thanks John. How you doing?
I gotta try this on my 07 Silverado now. Great instructional vid, man.
Thank you for the comment . I hope you find the issue.
Working under the dash laying on your back is tough. Also trunks are no fun either. I installed car stereos back in the early 80's. I can still remember lying on my back in a trunk cutting speaker holes for 6x9 speakers in the rear deck. The goggles would fog up and the metal would still find a way into your eyes,shirt ,you name it.Still have stiff necks from it after all these years. Your vids are awesome.
I know exactly what you mean. I never installed speakers professionally but I have done a few. My first car was a 1959 BelAir and the putting speakers in that was great because the truck was massive. But every other car I did was a pain in the back. It's funny the things we remember, thank for the comment Mike.
People tell me I have a screw loose. I hear something rattling, so I think they're right, but darned if I can find the source.
Good job, bro.
:)
It's all in your head. :)
@@wyattoneable Ah, whew! That's a relief!
ive been told i have a screw loose to.lol
Nice job finding the problem. 👍 I'd probably still be stuck checking fuses if that was my problem.
Hi Zib, nice to see you here. I had a clue it could be the brake switch or related wires because my cruise control was acting up as well. Now I have brake lights and cruise control!
I believe I have the same issue on my 2006 Dodge Ram 2500 after an after-market trailer e-brake was installed...will be checking cables tomorrow! Thanks for the lead!
Good luck!
Very good and Congrats on the 3k plus subscribers Wyatt!
Thank you very much Sepp. I always relax when I watch your videos. This is too much work here. (ha ha)
Great work, Wyatt.
Hello Jake, thank you for the comment.
Great video Wyatt thanks for sharing another one. Stay safe
Hello Rick. It's always a pleasure to see you here.
Nice job finding that ghost under the dash.
I need to lose 50 pounds. :)
Great video bro, my first thought was maybe a fuse out but was a wee bit more than that but you tracked it down and sorted it. Nice fix. All the best
You're on the right track. That's the first thing I checked too. It wasn't that easy right? But it's done and I'm happy.
Tight squeeze in there for me too :) well done buddy 👍
Great to have you here so early Steve.
Great repair Wyatt. Had to fix mine last summer, man that was tough. No room and everything in the way. Trust me no cameras were used, i would have to bleep it a very 5 seconds if I did.
Oh yeah, there was no way to get a camera in that hole. I filled it up myself! (ha ha)
Nice work as always.
It's my only truck now. I need to bring it up to code. I sold the camper yesterday. Kind of sad.
Bought a 1998 Chev k1500 used and no brake lights. And I believe I do have the same problem at the Relay. need to get me a new tester to make sure. Thanks for the video.
Best of luck with the 98. I appreciate that you made a comment.
Heck yeah man. Keep the vids coming.
Thank you.
Great job. It’s always nice when the damaged wiring can be removed from the vehicle for repair and even better that a repair connector was available.
Yes sir, I got lucky on this one. Access to the connector was tough but I was glad I was able to get it out. It made the job much easier. Thanks for the view and for leaving a comment. Always nice to see you here.
Good video Wyatt. Know how it feels to get under the dash. Can still do it but sometimes it's a challenge. Maybe the hardest part is getting Bach out. Lol. Like the way you used the clamp. Have quite a few of those as I also do woodworking. I'll give it a try. Thanks again for the tips and video 👍👍👍
I sure appreciate the comment!
@@wyattoneable Anytime my friend Artie 👍
Great job Wyatt! That was like me under the dash today lol I had to reinstall the glovebox 3 times cause I kept forgetting to plug stuff in, thought I'd try a shortcut .... Nope! Had to take it all back out again and I still forgot to plug in the glovebox light! Will start again tomorrow 🙄😂😂😂
Ah that's aggravating. I hate going backwards on a project. I'm glad you got the patience to take on a project and see it through.
Lol it was really because I lost one of my diamonds out of my engagement ring and it just snowballed into taking the seats out, fixing the scuffed leather, shampooing the carpets while I had the seats out .... 🙄😂 Didn't find my diamond though 😔
Good morning! first video of the day with a cup of coffee.
Your up early too. I couldn't sleep so I got up. I have to wait for coffee as my wife is still sleeping. Thanks for watching.
You did it nicely. Thanks
Thank you!
A fix like this is satisfying, excellent diagnostics and thoughtful recording!
Thank you very much. It means a lot.
thanks from sweden 🇸🇪
Thank you for the comment.
I spent all day yesterday fixing the brakes on Grayv's S10 Blazer... had a real bad grinding noise which turned out to be a broken caliper...it trashed out a new rotor and brake shoes in less then 2 months. Had a beck of a time getting the brake line fitting not to leak on the new caliper... But that's the way it usually goes for me when i try to get things working right. LOL
I sure wish that Toad had a garage setup like yours though... it was HO HOT HOT yesterday!
Sorry to heat that Les. Doing the work ourselves saves money but sometimes working is such a headache!
Boy do I hate crawling on my back under a dash! I have a hard time breathing as it is ... but when I get myself all pretzeled up in there on my back, it cuts my lung capacity in half for some reason. I get pretty ornery working there for any length of time! 😂 You get BIG respect from me because you don't have to do it ... but you DO IT anyway! And do it well, I might add. 😎👍👍
Nice find, and great video, Wyatt! Thanks for the kind words at the end, too. 🍻
Well thanks Smitty. I've always worked on my cars. In my teen days I couldn't afford shop labor so I think it's become habit for me to "figure it out" as my dad says and do it myself. When I first met Eric I told him I wanted to learn how to diagnose cars because I thought I would flip them as a hobby. That hasn't happened yet, but I do enjoy this path of learning and meeting cool people along the way.
@@wyattoneable - Exactly how I got into this trade. I paid for a brake job once as a teenager, and my jaw hit the floor!
My grandpa worked out of his home for years, but that skipped over my dad - he hated working on stuff, lol. He'd only do it if he had no choice. I picked up where my grandpa left off. Yeah this whole RUclips thing has been fantastic, both with the automotive videos I watch, and the aviation side of things. I'd never have considered buying a paramotor without RUclips! What an amazing thing - didn't see that one coming 30 years ago, lol. Glad to have virtually met you as well.
@@SmittySmithsonite I'm the oldest of 5 kids, three boys two girls. Me and the next boy down both work on our own cars, the third brother??? Nope, not a chance. I think he's the smart one. But yeah, the downside is he just had a fuel pump replaced by a dealer at the cost of $780. I looked up the part on Rockauto and even the high end price was $300. That's when I'm like "Yeah, I'll keep working on my cars as long as possible".
@@wyattoneable I have 3 brothers and 2 will work on them one won't, always makes it sound a little beneath him. I watch Eric a lot and just did brakes on my wife's 2009 forester both ends calipers and all. The central Ny state crusties! Been working on my own for 50 years, turned 66 in july.
@@wyattoneable - I hear that, Wyatt! I'll be doing this until they put me in the ground. :)
I don't like anything under the dash. I should say, under the dash don't like my back. Nice fix.
It's a terrible position to try and work. I'm happy the work I did fixed the truck or else someone else would have gotten this job. :)
good thinking by putting on the flashers to check the bulbs and nice splice work! my harbor fright light just fell apart, that plastic link at the bottom of the bulb fell apart... its under 90 days I will try to warranty it.... or ill buy another for 25, I like the tip light it has I think I have had every brand none last
That's a bummer. I think they will replace it. My HF is pretty good about that. Thanks for the comment scuba.
Really help’s 👍🏽
This is my most watched video. Thanks for the comment.
I just had to take apart a connector that looked just like that one for a blower motor resistor. Mine had a couple wires that had drawn enough heat to melt that connector on a couple of pins. Luckily I was able to keep the old wiring for all but two of those wires, and now I have some specialty crimped wire sections ready for the next one that comes in with a similar problem.
Sorry man, I had to look into my spam area to fond this comment. I don't know why it's doing that. Thanks for the comment.
@@wyattoneable mines doing the opposite..the on the relay test..my brake side works. But the hot one that suppose to stay hot doesn't work 😒 what is the problem
Looked like a super comfortable position to work in. lol
I pinched a nerve in my back a couple of days before so that just added to the pleasure!
@@wyattoneable Oh FUN! Hope it is feeling better!
EEEK
Under the dash is the worst
Great video
Especially when your old and fat!
Cool .... I learned something .... let you fix it! LOL
ha ha. That works too.
Great job Wyatt. I wonder why that harness failed 🤔
The wires move with the brake pedal is all I can think of. They became weak over the years. It sounds reasonable to me. :)
Smart guy!!
I appreciate that. Thank you for taking the time to watch and comment.
Man I am here late for me! Great find and fix Wyatt. Hey saw the Easyrider movie poster in back Guess you heard Peter Fonda died. Damn!
Yeah, sad news. When I saw that movie in 1969 it changed my life. When I watch it now it seems like a silly movie. But it still has a great following.
@@wyattoneable well I still love watching it!
You mean you didn't throw a relay and a new brake switch in first? Amazing what a diagram and a simple test light can do. Nice work, Wyatt!
I'm learning the right way thru all the smart guys on RUclips. :)
@@wyattoneable Exactly! What I have learned from those guys over the last few years is not insignificant. Putting their knowledge to work in my garage has been extremely rewarding.
Thank you for the easy to follow instructions.i have about the same problem so gonna give your instructions a try.just wandering,i have a trailer brake switch at the bottom of the dash.when i depress the trailer brake switch should the brake lights come on also?thank you for your help
I hope you find the issue. Normally the trailer brake light switch will only illuminate the brake lights on the trailer. Of course if someone wired them differently then who knows?
Thank you
I'm glad it helped Chris. Come back anytime.
Had a similar thing. My truck was already rewired with new pice. Wires where just loose. Check all fuses first...would have never know where to go next. Thank you
Thanks for leaving a comment Craig. I'm glad it worked out.
Hey Wyatt I am having the exact same problem as you and I'm trying to get that wire out but I cannot unclip it. How did you get to it with all the stuff in the way? I replaced the brake light switch and that did not work. I saw your video and checked and sure enough my wire looks just like yours
Oh gosh, this has been a while. I do remember it was tight up in there. I may have used a long handled pliers to reach the connector. I know I've done that before in tight areas. I hope you can be flexable enough to get it replaced. Good luck and thanks for the view and the comment.
good useof that clamp i have to check if mine will due that.
nice vid. good diag. under dash stuff not my favorite either ,rewired a head light switch last sat. on an old rambler melted poor grounds.
That clamp came in handy. Thanks for watching and for leaving a comment.
@@wyattoneable your welcome!
2 foot breaker bars works on my '96 Silverado brake pedal
What ever works right?
Heck I'll drive from Illinois to have u fix my wiring if it's the issue lol
That would be a long drive but I wish you luck in finding your issues. Thanks for writing something in the comments and welcome to the channel.
It's also been very hot here in California.
I lived in Ventura and it would stay pretty cool along the ocean but drive 10 minutes towards Ojai and it would be 30 degrees hotter. You must live inland a little?
wyattoneable Yes I live inland. It’s a big difference in temperature when your close to the ocean.
Kind of odd this connector failed? Did it get hung up on the mechanical portion of the brake pedal?
They move with the brake pedal so I'm thinking the motion over they years just wore out the connection points. No signs of being worn or of contamination. Thanks.
I don't know if this would help you, but I keep a string of electrical tapes, all different colours. I can tape my wires the colour I want as I go. I still havnt got my jeep back yet. When I get the little thing back I'll film it. It's quite a funny little thing. laterz Wyatt
Hello old RUclips friend. That's a good idea. I have different colored tape in many different locations throughout the shop. It's time to consolidate. 😉
Yo tuve el mismo problema con mi 1999 gmc suburban
Where did you disconnect the connector that does not come from the brake switch? In order words the cube shaped connector. TIA
That's hard to answer because it's just the other end of this harness. If you have a similar truck it's a matter of following it to where yours goes. It connected to another bundle of wires related to part of a total wiring harness. That's the best I can do.
I can feel my relay switching when brake pedal is depressed. Is there still an issue with the wire harness?
That's impossible for me to guess from here. There are so many possibilities. You have to narrow down the issue by going thru the things you know are good, like to make sure you have a known good bulb.
Sma sent me here. Hello!
Hello, nice to have you here.
thumbs up
Thank you sir!
Nice fix, sure would be nice to have a little more room under the dash.
I thought about pulling that seat out for more room but access under the dash was still an issue. They left no room for working that's for sure.
Do the suburbans of these years not have a brake relay when looking in my under the hood fuse and relay box there is no relay or metal prongs for a relay and my 30 amp fuse is missing a metal prong for the other side of the fuse? Great video.
I'm positive they have a brake relay. The fuse box cover should identify that relay.
Only asking because on the diagrams i have found it says except suburban/ utility. So it makes sense that my fuse and relay box doesnt have the pins for it. It is identified on my fuse box cover but like i said it is not pinned for the relay and one side of the 30 amp fuse is not pinned also.
I am having the same problem 99 suburban dont have that relay but on my 98 Silverado does have it... so I swap out my 98 motor to a 99 suburban now my brake lights don't work and the 3rd brake light stays on.
Any suggestions
@@tony-ynot9770 It's hard to diagnose a problem without being there. I don't know what changing an engine would have to do with the brake lights not working. Maybe just a coincidence?
Where did you get that connector?
NAPA
Hey 👋 friend. I am new on your RUclips channel. How do you feel today? I saw you on sunshine’s channel. She is a friend of mine.
She's a hoot right? I'm married to a German so I get it. (ha ha) Welcome.
Do u have diagram for a95 Chevy 1500 brake light switch
I have access to Alldata DIY addition. You can get what you need there but it costs some money to become a subscriber to the website.
If u have an electric drivers seat a 2x2 or 2x4 also works fine.
So true.
My day time run tailights light up when headlights are on, but no brakes.. all fuses good what can be the problem.. ford ranger
It's difficult to diagnose a problem over the internet because it could be many things. I'd start with checking the brake switch.
I have several fuses that don't work when being tested in the slots, however fuses aren't blown. I move those fuses to other locations and they do work, just not in the slots where they belong. When pulled out and inspected, the two silver prongs look burnt. What does this mean? I have a total of eight fuses that do not work and are burnt from pins but still function in other slots. Has anyone seen this before?
If the fuses work in other slots then you have no power going to the slots where they did not work. Burned pins are an indication of a bad connection. Try cleaning the pin and the slots with sandpaper and see if that helps.
What if I dont have power to the constant on the relat
Then you'll have to find out why there is no power. Without a wiring diagram I wouldn't know how to help you. Sorry.
Oh dear. Yes. I know what you are talking about. Had the same issue with my Smart 44 (dont laugh! It is still a car!! ;)) So I went to my lovely mechanic who doesnt charge me like mad, cause he is a good dude. And magically he drove around 2-3 times and unlocked the wheel and it was good again. No one knows why?!! Good to make a test drive, of course! ;)) Sunshine
Sometimes a fix a car and don't know how I did it. This one wasn't so bad but yes, some cars are crazy. I won't fit in a Smart. (ha ha)
@@wyattoneable lol!! it is a 4 by 4!! :-D
How come the wire are not color codeed?
My guess is this part fits different applications.
If you have a bad socket what can be used to test it?
I'm assuming your talking about the socket for the brakes light bulb? With the brake pedal applied you can check the two connecting points with a known good light bulb or a multimeter.
@@wyattoneable
Yes I'm referring to the bulb socket. I just happen to have a multimeter.
@@wyattoneable
When using a multimeter to check the bulb socket which setting should the multimeter be on?
@@CrowdPleeza DC volts
I have the same thing except no power to constant at rely?
You have some more work to do. I hope you find the problem.
I found it loose connection at fuse box what a pain in my butt
Bolt for brake loose
Can this working 1990 Chevy 1500?
Yes. It is the same system but you may have a different problem. Good luck.
I replaced the brake switch and still no brake lights. Only running an turn signals work. Also check the fuse and it’s good. I checked for power on the brake light cable on the harness and I don’t have power when stepping on the brake pedal
@@a.alcantar5794 There is a brake light relay in the under hood fuse box too (at least there is on mine).
Yes I do thanks anyways
nice trouble shooting
Thanks. I still have a lot to learn but since this is a hobby I'm enjoying the challenge.
Damn Chevy's. 🤣😂
Wait until your Ford gets 200,000 miles on it. If it lasts that long. (ha ha)
For dumb people like me it would be nice to know where that part you replaced came from/goes.
The part number of the brake light switch connector I used is on the box around the 3:35 time stamp in the video. But your vehicle may be different so your local parts store can look it up for you. Thanks for watching. They have gotten really expensive so good luck.
Thanks, very interesting. I have two loose wires in my fuse box area and I am not sure where they are suppose to go..1997 Dodge Intrepid...anyone have an idea...they have a little sharp pointed brass clip on the open end???
Without looking at a wiring diagram it would be impossible to speculate. I hope you get the answer you need.
Ny breaklights completely stopped working, hazard lights still work though
i switched the breaklight switch couple days ago and it worked for a few days but now breaklight dont even turn on when i unplug the switch. Could the new breaklight switch messed up the wires ?
It sounds like you may have a short in a wire somewhere. Is the fuse blown?
