Weird beeping while driving

So just happened and can’t get it to go again.

Drove for about 10 miles, was driving about 45mph in 4th gear, downhill not much gas.

All of a sudden I started hearing a beeping noise. Same noise when you leave parking brake up. Checked parking brake and it was down all the way.

Started to slow down to pull into a parking lot and as I pulled in it stopped.

All gauges were in normal operating range. No dummy lights, other that the airbag light that’s been on since I bought the Jeep.

Have driven the Jeep about 40 miles today just running a few errands.

Should I chaulk it up as a 14 year old Jeep gremlin or does anyone know of something to check or keep an eye on?

Yeah no turn signal on or anything.

It was weird.

I’m picking up my daughter and I might try to go the same route to see if I can recreate it. If not, I’ll just chaulk it up and move on I guess.

Lol.

I actually was able to recreate the beep. Again going downhill about 40mph in 4th.

I also noticed that my blinkers are barely blinking with the parking lights on. Just replaced them all with some LED and an LED flasher relay. You can barely tell they are blinking with the parking lights on.

Might go back to non-led relay and see if the blink brighter with parking lights. I know they will hyper flash but atleast I should know if it’s the relay or the bulbs.

It is the LED exterior lighting. Keep the LED relay. The LED's will change the input voltage to your blinker circuit and your instrument cluster will start beeping because it will think your blinkers are on for an extended time, seeming randomly like a mind of it's own. You need to reduce the voltage to the left and the right blinker wires coming out/in of the instrument panel by using proper diodes or resistors or both. A LED load reistor, one for each wire, under the dash on a proper metal mount should work too.

And don't forget to add blinker fluid to proper level... 😉🤣

My aftermarket multifunction switch will sometimes act in a similar way, I jiggle the turn signal lever and it stops.

I had the same thing happened to me while driving 45mph and in 3rd gear. The beeping sounds like the ebrake reminder beeps and comes on randomly.

My problem was either both the multifunction switch that was going bad and rusted contacts on the front turn signal bulbs. Replaced the turn signal bulbs and packed it with dielectric grease. JB weld the stock multifunction switch (there's a model fix on this) and all is good.
