This is a blinker relay. It is usually shaped, on a Jeep, like a cylinder and in some cases like a square. It is located under the driver dash usually within the fuse panel. It simply pulls out, usually with a bit of extra force. Read the part number off to your local parts house and they will have it in stock 9 times out of 10. Simply replace and align all of the pins, push firmly into place and the blinker should be restored to normal. *Be sure to check all of your bulbs because blown bulbs will also cause undesired blinker flashing or lack thereof. Hope this helps, good luck!

Seems like an Earth problem for the RH lights.
Grab a Jumper lead. Attach one end to a good earth (engine or Neg. Battery post).
Other end to the RH metal mud guard.

Left turn signal not working but blinks real fast when put on

sounds like burnt out bulb. This is usually an indication when the bulb blows. Turn on blinker and check front and back to see which bulb is out..

Why are the turn signals not woring on my jeep?

Without any details I could only advise you to (find) the "turn signal" (plug-in", it is actually your "blinker". If you can not find it call a (auto parts) store and or the a dealer for your type of car. They will be very happy to help. This "blinker" I refer to is (not) expensive. Good Luck.

2007 Jeep Grand Cherokee..tail ligts and blinkers do not work when headlights are on..they work otherwise..another problem when headlights or running lights are on and I use left blinker, it blinks...

mporteous, It sounds like you have a light switch problem. I can't think of any other reason for the running lights and tail lights not working in this situation. Are your brake lights working when the headlights are off and how about when they are on? Do your four ways hazard lights work in these situations? Try all the lights under these conditions. The reason the left turn signal blinks very fast is because one of the bulbs are burned out. Try the left signal and one light (front or back) will stay on and the other will not come on at all. Replace the bulb that does nothing. Do this before you try all the lights in different situations. I think that you will have to replace the light switch. Good luck with this.

Ihave a 1999 box cherokee. The turn signals won't come on but the hazards will?

Assuming all bulbs are good, you could be looking at the Combination/multi-function switch/module. Basically it's your blinker arm switch which is attached to a module that is housed in the steering column.

Turn signals blinking fast and stop when brakes applied

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)

Intermittent left turn signal - 1999 Jeep Grand Cherokee

Generally, if a bulb has failed or is making only poor contact, the blink rate will increase since the standard blinker relay uses a thermal strip heated by current flow to the bulbs and when it is too low, it blinks rapidly and briefly.
You still have the front bulbs to check and maybe pulling the fuse for that circuit and plugging it back in might remove some corrosion from the blades.
The flasher relay is probably OK since this would affect both sides.

YJ Blinker Relay

Hi there,

Both the hazard and the blinker flashers are located on the fuse panel. They pull straight out.

When both turn signals fail, the cause may be a blown fuse, a faulty flasher, a broken turn signal switch or a bad connection.

When you try the turn signals, do they light up and not blink?
-If so, probably the flasher unit.

When you try the turn signals, does nothing happen?
-Check the fuse

Let me know if the problem continues after replacing the flasher.

Blinkers not working

Did you check the bulbs? If one bulb is burned out, the blinkers won't word on that side. You could have one bulb burned out on each side. Start the car, put left signal on. Check front and back lights. Is one light on but not blinking? If that's the case, the light that's not on at all is burned out and has broken the circuit so the good light stays on and won't blink. Check the other side. You also have a 'flasher' , actually 2. One for emergency flashers, one for the turn signals. It could be that the turn signal flasher is shot. You just have to unplug it to remove. It's probably located near the fuses. good luck countrycurt0
