Question about 1997 Jeep Grand Cherokee

2 Answers

Fast Blinker When the headlights are off both blinkers work fine and at a normal speed. When you turn the headlights on and the left blinker on at the same time, the left blinker blinks very rapidly. The right blinker remains at a normal blinking speed. My blinkers (rear and front) blink fast on the driverside only when my headlights are on. The passenger side blinks normally and both sides blink normally when the headlights are off. Are the headlights connected to the blinkers in the wiring? And how do I fix it without bringing it in?

    I think you have a ground problem with the turn signal lights or the headlights, you should check, verify, and clean the ground wires in both sets. The headlights and blinkers are only related by power and ground in the circut

You have a bulb on the left side that has both filaments touching inside the bulb. Remove both front and rear bulbs and get replacements at an auto parts store.

Usually a fast turn signal means that there is a light out. You should probably check all of your lights, including back-up lights, and turn signals. If there is one out then replacing the burnt out bulb should fix the problem.

The problem could be the wiring connecting to the lights, you need to check them for bare wires. Look them through for any metal hanging out of the rubber insulation. You may need to get new wiring.

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.

There is a short or something is broken in the multifunction switch (headlight/turn signal switch). It will most likely need to be replaced.

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.

Have you checked to see if you have a blinker out? If you do, then thats your problem. If not, check your blinker fuses. Hope this helps, James Booth.

Left blinker is fast front blinker light working left rear blinker light not working.


When a turn signal bulb is blinking fast, it is an indicator that a bulb is bad in the system. Replace the left rear turn signal bulb, then see if the left front blinker has gone back to normal. This is most likely your problem. Let me know if it is still a problem and i will help you fix it. Good luck

Left blinker blinks faster than the right. which the back left blinker does not work and front left blinks really fast.Right blinker works normal?


Flasher relays relies on bulb wattage for the speed of the blink.
You probably just have a blown bulb in the left rear blinker.:)
