Turn signal/ Hazard lights going crazy!! help!!!

so im having a bunch of turn signal/ hazard light problems lately and im looking for some help. Yesterday I first noticed that my right turn signal was not blinking, so i did some tests today in the garage and figured this out.

First my hazard lights have not worked since i bought the jeep a few months ago.

now today.....
when jeep is off and headlights are off Hazard lights turn on about 90% of the time 5% they dont. other 5% left turn signal blinks fast
When jeep is off and headlights are on Hazard lights do not blink but do turn on

When jeep is on and headlights are off Hazard lights turn on and blink, Left turn signal works, when i put right turn signal on hazard lights turn on
Whan jeep is on and headlights are on Hazard lights do not blink but do turn on, Left turn signal works, When i put right turn signal on it clicks once and stays on (does not blink)

so what do i do?

Sometimes the problem can be really simple, my jeep would do the same thing and it was just the battery terminals needed to be tightened. maybe you could try that

Do you have any buddies who have jeeps the same or close to the same year as yours? you could try swapping the turn signal switch and relay to see if it helps. Also do you have any LED lights wired up?

My jeeps right blinker light comes on with the headlights and blinked fast. I found it to be a bad connection in the right front connection. I can get out when it does it leave it on and go wiggle the connection and it starts working. Havew not had time to pin point what is the true problem, bad connection or loose wire

Im not a pro on vehicle electrical, but always check grounds first. Bad grounds cause all kinds of strange problems. (Actually always check fuses first then grounds but yours doesn't sound like fuses.)

RH turn signal is the longest wires, i.e. the most resistance, most often the first to fail with a signal flasher going bad. Have you tried the $5 fix and just replaced the flasher unit? Rapid flashing is sometimes a symptom on those. You also may have a bad ground in one of the signals, have some one observe the brake lights, is one dimmer than the other? Is one of the front signals dimmer when you can get the 4 ways to work? Does stepping on the brakes make any difference?

I would replace the flasher (multifunction switch). It controls all of what you described. It's only $20.
Mine kept coming slightly unplugged, so I taped it tightly together with electrical tape and I haven't had any problems since.
