Installed led bulbs for brake/turn signals in a 1994 YJ. Changed the relay & everything seemed to work fine. Then discovered the front side marker/signal only works with lights off. Lights on they don't work at all. With stock bulbs they did work with headlights on. How can this be fixed?
Mods, it's a modifcations post. rare... here...
first off ,you did willingly break your car, why do that.?
and if car has issues later on the road, the mechanic will hate you for this.
he may in fact say, sorry buddy, take it to a custom shop....
(it is your car, but...... think about the future... and resale, id never
buy your hacked up car. me and millions like me.... )
but if so inclined, you take the factory drawings (FSM)
then red ink the mods.
then post it and i can answer with 100 % accuracy,
your lights on off post makes no senses
my guess is the park circuits are crosswired.
one big failing with LED modders. is the lack of understanging
that some components on the car are sensitive to current'.
or have normal leakages. bad for LEDs.
that would just hate LEDs.
and the one in this car is not SPECIFIED.
how many LEDs did you install and where, we got the turns stated.
are you LEDing the Park circuit too ? aka TAIL?
the hazard module in the column, is an electronic type module.
the jeep lights are oddly wired,
see the schematic below. see how the
1 lamp element us used for many functions?
ignore red balls, they are for brake failure only.

the blk-yell is the park feed. if the park switch leaks, the LED will glow easy. . keep in mind the switches being old and the grease starts to conduct (metal wear ) and at 0.010 amps the LED glows.
so fails. a 1 amp factory lamp draws 100 times more, so will no glow.
see? the only solution to that is a new combo or removing all the nasty old grease in the switch. (im a certified tech, retired and see it all)
now look at the tan wire. ( the brake/ turns are shared , on jeeps)
see the TAN?
see how the markers are wired to brake turns? feed>?
odd , huh?
for sure the LED usage will in fact find all current leakages in the whole circuit. just 10/1000th of an ampere and it glows,
i hope this helps, but do post the mods to my drawing.
and we can in fact find any failure. any leakage,
sure can. with and accurate drawing and a meter.
good luck.

I had this same problem on a 1995 Lincoln Towncar -- thought I might have to replace the Signal Switch - then it was suggested to check the ground for this wiring. However I was told to check the HAZARD SWITCH. The Hazard Switch was not On or Off it was stuck in the middle. Simply pushing it up and down correct the problem. I was also told that maybe a little WD40 on the HAZARD SWITCH might help.
This is an easy try me first fix. It worked for me and cost 0.

I had the same problem with my 1999 Yukon. The electric board needed to be replaced. Rust starts to build up and shorts out or blows the bulb. The dealership charged $73.60 for the part and I installed it myself (Saved $30).

Find the ground wire on one of the lights and add another ground wire to a good clean metal surface and see if that fixes the problem. It defently sounds like a ground problem at one of the lights.

on my 2006 dodge ram 3500 5,9l same problem with headlights and turn signal , the problem was with a fuse box , i replaced the fuse box everything work just fine.
