Turn Signal Relay Acting Crazy

Okay, I searched this and couldn't find much for a conclusive answer.

2000 jeep tj, 4.0 i6, 5-speed tranny.

My signal relay has been acting crazy and i cant figure it out. First i had the OEM flasher relay and it was clicking very fast like i had a signal light out. It would only click fast like that when i wasn't using the signals or hazards. If i flicked either of them on to use them they work perfectly like normal.

Logically i thought i needed to replace the flasher relay, so i did. I got the new one in and the problem was gone for maybe 10 min. Then the new relay, instead of clicking fast, started buzzing like crazy. I replaced all turn signal bulbs because i found a post saying it could be corrosion. nothing changed.

Any ideas? The signal still works like normal, i just have to put up with intermittent, and incredibly annoying buzzing noise.

First thing I would check, is the ground connection on the flasher relay itself. The black wire is a ground. Try using a jumper lead from there to a known good ground and see if that solves the issue. If not, the flasher gets it's power from the hazzard/normal switch (red/white wire), then delivers it back to the turn signal switch via the pink wire so there's a posibility that one of those switches is malfunctioning and both are within the multifunfuntion switch.

Could also be a pinched wired in between.

No, no, no. Its a simple fix. You need to change out your blinker fluid. Buy a bottle at autozone and call it a day.

It's likely the multi function switch.

mines doing the same thing right now, clicking like crazy. it started after my jeep got poured on yesterday with the hardtop off. the multi function switch might be shorting out internally.

My relay started clicking like crazy after a very over-zealous high pressure washing under the fenders. So I'm guessing water got in the fender lights.
Clicking became less and less random then eventually stopped after 7/10 days.

Wouldnt i need the multi-function blinker fluid instead? Is it in the same isle as the clutch lubricant and the blinker diversion valves?

Really appreciate all the suggestions guys. I'll try and report back what i find after troubleshooting it a bit better this weekend.

I didn't know this was such a phenomenon on the internet. It's most definitely real. I don't know about you guys, but I'm getting some.

What the heck is blinker fluid? I've never heard of it. I've heard of brake fluid, tranny fluid, window wiper fluid. Learn something new everyday, I guess.

The girlfriend ate up most of my time this weekend so i wasn't able to get into fixing this issue. On the plus side, it hasn't been doing the buzzing thing much at all.
