How To Fix Blinker and Tail Light Issues on a 73-79 F150

- When I started working on this 1977 F150, I had some bulbs that weren't working. So after replacing the bulbs, I thought I was finished. BUT, when I would turn the headlights on, the turn signal bulbs on the dash would light up. I also noticed that the bulbs on the front of the truck were not lighting up with the headlights on. And to top that off, when I would turn the blinker on either side, the little light that lights up the headlight and windshield wiper knobs would blink! What I ended up figuring out is, if your ground wires in the blinker and tail light sockets aren't making a good connection, this is what's going to happen. In the video, you'll see how I was able to fix this problem with the existing sockets. In all honesty, the best thing is to replace the sockets. I've got some ordered and will be replacing these. Please drop any questions you have below and if you think the video was helpful, please subscribe. More 73-79 F150 videos will be coming. Thanks!

Thank you for making this because everywhere I found has been absolutely useless
Glad I could help.
Thank you so so much for the information. Bought a 1978 to work on with my grandfather and he passed away before him and I could even work on the thing and being in my 20’s, I have no knowledge of car systems older than I am!😂 Thank you again for posting what you found.
My 78 f 150 has had the same symptoms for 7 years. Tried everything. Watched your video and an hour later it's fixed! My ground contact was completely rusted and broken off. Finally I have turn signals and marker lights. Such a relief! Thank you so much for this video!
Glad it helped, that’s awesome!
Same problem on my 74, thank you for the video. Very informative, going to address this tomorrow.
I just got done changing out the rear tail/turn signal sockets on a 76 for a friend of mine...bought the dorman replacement sockets....worked great...couldnt find new sockets for the backup lights...i bought 2 more tail/turn signal sockets and used them for the backup lights..the sockets fir perfect into the housing . I just hooked up the red wire on the new sockets to the hot wire for the backup light...that way it uses the bright element of the 2 element bulb...taped the extra un used wire out of the way
Dude i fought this issue all weekend and finally found this video, had it fixed 10 mins after! Thank you!
That’s awesome, glad it helped!
@@TheKeymaster316 I have same problem works for 10 minutes after that nothing and wen I brake that from signal light up like that tail brake
I've got the same problem.
I'm going to look at it this afternoon thanks again
thank you i was just setting out to troubleshoot the same problem and found you video the first and only one i needed. success! job done. thank you x100
Glad it was a help to you, right on!
I’m about to start tracing my tail light issues on my ‘78 and this video should save be so much time. I haven’t opened anything up yet but I assumed my intermittent tail lights were a ground issue (only had the truck 3 days). Thanks for the info!
I hope it helps, good luck!
Thanks for the info, I have a 79 with the same problem in the front drivers side, now I know what to look for. I like your rims to cause i put the same ones on my 79.
57truckz I’m glad I could help. If you have any questions, please let me know.
That was the whole problem you are a lifesaver. Thank you so much
Glad I could help!
Thank you for the video. I replaced all my lights with led lights some were not working before i replace the with leds. Ordered new sockets they all work now.
Glad everything worked out, that’s awesome!
That thing you found in the garage to stick in the socket is actaully the headlight switch rod...if your looking for it thats it. Also having the same issues will give it a shot thanks
gear head yes, I did realize that later on. Was missing the knob so I didn’t realize it at first. But it makes a great ground rod!
76 f100 stepside. you fixed it. thank you. good info.
Glad to help.
Thank you a million times
The best way to check electrical issue with those old ford's is to disconnect all fours harnesses to the head lights and markers. Lift the hood there's one square connecter on each side near the inner fender and on the back of the box under Neath . Once u disconnect turn key on and check cluster for blinkers working. Now plug one light in at a time and check for faults example flicking dimmer ect. This way you can determine where the fault is. Then go from there
Sounds like a plan, I’ll definitely keep that in mind the next time around. 👌🏻
looks like going little further into depth tomorrow, just needed make sure was going into right bag of worms, rear turn, but not when lights r on, front don't work at all, they did work until I added missing front l bulb, and replaced burnt out turn on r side front. so think my ground s are n plugs need some attention. Nice video.
Your video helped a lot. I knew I had a ground issue in the front right. And after some continuity testing (as shown in your vid) I found the issue. Unfortunately, when trying to get the ground wire out the socket, the wire let loose in the connection. No way I could get that out (corroded). So after getting a new socket and wiring that in, problem solved. Thanks again!
Man, that’s awesome, I’m glad I was able to help!
That little triangle shaped rod you are holding is ironically a head light knob rod with the pull knob removed.
Thank you
I replace my signal switch that in the column and my signals still not working not getting power to my relay ether but when i turn signal on hold my brake the signal cut off my brake light and don't flash just off i run new ground don't know what else to do replace all bubs
Can it be the same problem if my brake lights don’t work but my turning signals do?
I grab my replacement sockets from the newer vans that share the same taillights.
I have this issue.
But mines on the rear.
I have no lights on the rear but the left turn signal.
Everything has been replaced and i have no power to the harness.
Turn signal advantage headlight switch had been replaced.
Its so frustrating
I have a 75 that turn signal lights are solid with or with out heads lights on, been reading every forum I can find and I cant seem to figure out. its driving me nuts try to figure it out.
I’ll bet the grounds somewhere are the culprit. Good luck!
Could this happen with reverse lights as well or could that be a neutral safety switch?
I can imagine that you would have a similar issue with the reverse lights if the grounds were bad, for sure. On this particular truck, I swapped the column out, which originally had the 3 on the tree. The button for reverse was under the hood, but since I removed the linkage under the hood for the column, I had to rig up a toggle switch for the reverse lights. My current truck is an automatic and I’m not sure where the reverse button is. But I would always start with the sockets in the tail lights. Turn the key to on, put the truck in reverse and take a test light and see if you have power to the reverse socket.
So basically what I have to do it go around the whole truck and replace all the bulbs and check for rusted of burnt connectors
Possibly. Although you can repair them, they are so cheap, it’s easier to just replace them. 👍🏻
I am having a similar issue with my 79 but my blinkers on the driver side don’t work with the headlights on but work with the headlights off
Front and back
It’s amazing how much the grounds affect things. Make sure your grounds are clean and you don’t have any chopped up wiring held together with duct tape.
@@TheKeymaster316 yea and what’s bad is I checked the grounds but it still did it but buddy checked and mess with the front ground and boom working
Really random, but where did you get your wedding band?
I’ll have to ask the wife. 👍🏻. She used to sell Silpada jewelry, so it may be from them.
@@TheKeymaster316 thanks! getting married soon and haven’t found one I like other than that one. Also A+++++ on the video. I had 3 bad sockets on my 79 so you got me fixed up!
@@clinthughes2606 that’s great, glad I could help. And congratulations!
@@TheKeymaster316 thanks brother. If she remembers where it came from let me know!
That piece of metal is from a head lite switch.
Yes sir, just used it for the video because it fit perfectly in the hole. 👍🏻
Do you still want to sell thus truck?
Sonny Winstead sorry, need to edit the video. Just sold it a couple of weeks ago.
Can you solve your puzzle ring?
