My turn signals on a 2010 jeep patriot work for 3 or 4 blinks then start to blink fast and the front quit flashing. what is wrong

Wiggle the turn signal switch and see if those lights blink.

The flasher is defective.

why skip RR lamp? what does IT DO? be like 1st 1st look.
dim, out, fast?

the rapid is talking to you
it means current is wrong,
shorted, or open lines. to the right.
its the wiring
if the bulbs are like 1157 brass base bulbs
why not replace them first , they can short inside,
asking online for guessing is silly, why listen to 10 examples for this.
but is cut wires.
shorted wires.
keep i mind the blinker asks funny for both opens and shorts
its a feature, that.
low current or too much.

the acid test is connect 2 TEST bulbs in parallel to the multi-function switch output right side,
blinks ok now, bingo bad lamps or bad wiring, from there to the right side.

if the hazard fails you never said????
if rigth front is dim or dead the bulb is blown or shorted
if new bulb there , then the wires are shorted.
to it.
the only help on line worth squat is how to test and use your meter.
you can, check for voltage
you can check continuity on that line (its just 1 wire)
and check for shorts on that wire to ground (lamps pulled right side to do that, lamps read 0 ohms cold)
look for collision damage RF? behind lamp sockets?
be first.
in my book.
looking is always first. sure.


I have your SM book open now, chapter 8w-50
the haz/blink module has just 2 pins, left and right out.
pin 3 on the module runs front and rear blinks, (a fact to know)
RF is BR/RD, brown -red stripe?
all comments USA on USA forum. USA car.
ok?

the right side lamp (sidemaker) only blinks turns if parks ARE oFF

Id try 2 new blinker lamps front and 1 rear.
that be first. or test the lamp on a battery , and no not get burned fingers hot wring a shorted lamp.

wish i knew
what rear did
and what both did on HAZ
out, dim or to fast.

This indicates a bad bulb. Just walk around the outside of the vehicle while it's in the turn signal flash mode and observe which bulb is not flashing-replace bulb.

Try replacing with the same bulb type as was failed. Flasher unit isusually reliant on resistence from the bulbs to what speed that side will flash at when powered.Some of these led type have less resistence and that equates to a faster flash speed.That is why when one bulb blows that side will flash faster or may even stay on without flashing.You could even swap the led to the other side( to confirm.Check with the bulb retailer to whether they have those bulbs with a higher rated resistence in led.If this vehicle has leds as standard,you may need to get the correct type from dealer. Hope this helps or get back with findings if it still has fault after replacing bulb.

I just had that problem with my jeep cherokee and either your bulb has burned out or it is burning out. Time to replace it. Turn the signal light lever on the side that's flashing fast, get out of the vehicle and look at the front and back signal lights and replace the one that isn't blinking...hope this helps.

Normally when this happens you have a blown bulb on either the front or rear the fast blink is because with only one bulb working the flasher clicks it faster less of a load means faster blink.

likely not, but change /check anyhow....If problem persists, likely you will need to change the module that controls directionals (usually under dash to the right of steering column)

sounds like the bulb you have is the wrong resistance the new noen bulbs will do this
