/diy/ - Do It Yourself

Its the flasher relay, now get off my board

>>1475876
Is this something i can replace myself?i have absolutely no skills other than what I can YouTube....

I'd say water got in and corroded contacts in your lamp. Replace the lamp since it's not waterproof anymore. Had literally the same issue with mine.

>I'd say water got in and corroded contacts in your lamp.

yeah, those things can fill with water if bugs make homes in the drains

>>1475878
It literally plugs in like a fuse. It'll probably be in the fuse box in the engine compartment, where the big boy fuses are like the starter fuse.

>>1475880
I replaced the whole fixture about a year and a half ago. That dent you see above the light? Yeah, thats from me being stupid and backing up into a tree.....

>>1475876
If it’s this >>1475886 you can also try to get in there and swap it out with a known good relay, hit the switch and see if it works. If it’s blown, go buy a new one. Super easy to replace.

>>1475880
One of my reverse lights doesn’t work. Replaced the bulb and it still doesn’t work. Investigated further and the plug is all fuckin corroded. Tried to clean it up a little and still makes shirty contact so I gave up.

What’s the best way to clean that crap off? Maybe I will order a new connector or go to the junkyard and cut one off another car.

>>1475887
As a native american, I feel you need to go back to the tree in your jeep and do a what we call a repentance dance for it to work again.

It involves get drunk and backing the other side into the tree.

>>1475872
Did you use led bulbs or regular old school filament bulbs.

>>1475957
Old school bulbs. I wasn't about to spend 20 bucks on something that has an issue #jew

I need a wiring diagram or I'm completely in the dark here.
It does sound like the flasher like >>1475886
said, which is one of the countless problems with Chrysler products, but the fact that it's when your brake lights are on is odd.
need wiring diagram, I can tell you where to look if you can find one for your specific car.

check the ground connections, all of them
this is first to do on vehicle stuff

>>1476265
>1476265
This. Sometimes the ground is literally next to the light, sometimes it's way the fuck up under some shit.

>>1475872
>blinker works intermittently
I have the same problem.
It turns off and on and off and on.

>>1475872
Screw it change the tail light circuit boards if they are in the housing

>>1475949
Kek'd

>>1475872
If it works OK normally until you put your foot on the brake then you've got a dodgy earth. Find your earth points from the bulb(s) and clean them up.

Op here, so when you guys say check the ground.... the bulbs plug into a screw in socket like pictured, then there is a wire that connects to the entire fixture. Where should i be looking?

Before you touch anything electrical, disconnect the battery
If you find suddenly the light doesn't work at all check the fuses

19 posts in and the make/model is still unknown

OP when was the last time you changed the blinker fluid?
Be honest stuff happens

spit it out son
we are your friends we dont judge

start at the bulb with a multi meter and start tracing it back. You will find a cracked, split wire eventually. If by chance Johnny Dumbass installed a pigtail for a trailer...BINGO east fix. Only 3 wires to your tail lights not including ground

>>1478651
*4 wires

what i do in a situation like this is just run new wires

fuck tracing wiring waste of time

run new wires right from your switch back, ground each light seperately to the frame to stop backfeeding.

but in this case OP you put a single filament bulb in place of a dual filament bulb

go back and buy the proper bulb guy

>>1475872
have you tried turning it off and on again?

>>1478644
Oops. Its an 04 jeep grand Cherokee

>>1478560
Man, look everywhere. Look at contact points. Any residue, corrosion, burn marks. Take a multimeter with continuity mode, attach one probe to grounded metal thing in you car and other one to ground contact in fixture. Now fiddle with the cable. If beeper stops, then the cable is broken somewhere.

>>1478745
This is what I was thinking. It sounds like a fucked up bulb or one that's not a perfect match.

>>1478745
>what i do in a situation like this is just run new wires
youre full of shit moron it easier to trace a problem than this larper fagottness

>>1478745
I got the exact bulb the guy at the auto store said i should get..... 3157 for an 04 jeep grand Cherokee

>>1478910

the guy at the auto store is retarded

at least make sure theres 2 filaments in your new bulb

>don't eat tile cement
All are things that you should know and will aide you in life.

>>1475872
first problem is thay they're attached to a jeep

This is the classic indication that your ground (chassis) connection is bad. sometimes the bad connection is in the plug/socket to the light cluster. Find the connections, take the time to clean them up properly - and 98% chance that everything works.

Op here,
I replaced the whole tail light today. Im hoping that fixes the problem, so far so good, but like i said it was intermittent, so i won't know for sure for a few days.

And yes, this will be the last time i purchase a

I unfortunately drank the jeep koolaid while my wife was working for a dodge, Chrysler, jeep dealership. I think ive bought the car 2 times over now with all the repairs. Next vehicle will be a Silverado i think.
