Question about Jeep Cars & Trucks

1 Answer

2005 WH Jeep Grand Cherokee 3.0l CRD front right hand turn signal lamps will not turn off

Left hand turn signal lights work normally. They turn on and flash then turn off automatically. But the right hand side has a problem. The 3 front bulbs stay on solid (no flashing) and will not turn off with the control lever or the key. The only way to turn them off is to disconnect the battery or pull the FCM1 power fuse. The right hand rear bulb flashes but at double the speed. The integrated power control fuse and relay box is under the bonnet and is located next to the battery. When the right hand turn signal is active a relay for the trailer tow circuit clicks in time with the interior flasher unit. All the fuses in this power box have been removed and left out to test if another circuit Is back feeding the 3 front flasher lamps. No backfeed. The circuit earths must be ok because the lamps are on. The only thing not checked is if a input to the Front Control Module (FCM) is active? This can turn the output on. If the hazard button is pushed all lamps flash except the 3 front right than stay on solid. Any advice will be greatly appreciated.

Check the wiring to the FCM. If you have to replace it, it is EXPENSIVE!! http://www.jeep4x4center.com/jeep-grand-cherokee/front-control-module.htm

SOURCE: electrical problem

Find the ground wire on one of the lights and add another ground wire to a good clean metal surface and see if that fixes the problem. It defently sounds like a ground problem at one of the lights.

SOURCE: Tail lights don't work on 1998 Chevy Silverado.

check the wiring from the tailights back to the fuse panel, it sounds like an open connection. if i recall correctly check under the dash on the drivers side near the fuse panel for a bunch of wires in a bundle and look carefully for a wire or two that are cut/shorted/or seperated, you can also check under the drivers side kick panel by the hood release.

If you have trouble finding signal flasher, turn your right side blinker on, and follow clicking noise to flasher.

SOURCE: jeep - right turnsignal won't flash

Probably a bad ground on your front right signal, or a bad bulb. Try switching the right with the left, and see if the problem stays in the same place, or goes with the bulb.

How to fix my right brake light and fast moving turn signal on my 2000 Jeep Grand Cherokee?


The most likely problem is two burned out light bulbs. A burned out tail/stop lamp on the right side and a burned out brake lamp on the left. If you have already replaced the bulbs, then yes, the circuit boards are the next most likely cause of the problem.

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.

I need to know which connectors go to which O2 Sensors on my 2005 Jeep Grand Cherokee 4.7L 4WD. Can you help?


Hi, the easiest way to tell is by the signal wire color. These are the signal wire colors:
right front: dark blue/pink stripe
left front: dark blue/light blue stripe
right rear: Brown
left rear: dark blue/yellow stripe

On my 98 jeep cherokee when connecting the tailgate replace kit I accidentally touch the yellow left turn wire, with the brown tail light wire. As result my left side on the 4 way exterior dim lights no...


If it happened the way you described it. I don't see how it could possibly have damaged anything. I guess what you are saying is that the left tail lights are not working? ("4 way exterior dim lights"???) Touching the tail light wire to the turn signal wire will only cause your turn signals to light up. (I am assuming that the tail light switch was on at the time)
I think it is more likely that the brown wire touched ground. This would make a bright flash, blow a fuse and cause the symptom you are describing...I think you need to check the fuse again.
There are separate fuses for the left and right sides. The left side tail lamp fuse is fuse #7 in the junction block it is a 10 Amp fuse. The junction block is located on the right cowl side inner panel - We are NOT talking about the Power Distribution Center under the hood.

All of the above is also assuming that we are talking about a plain Cherokee, Cherokee SE, Cherokee classic or Cherokee Limited.

If we are talking about any of the Grand Cherokees, you may have a fried lamp outage module.

Pretty common problem if you have a weak or bad ground, check all the ground connections by the back lights.

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)
