1992 jeep cherokee all blinkers stopped working, checked flash unit and I dont think its a bulb becouse they gradually got weaker and more irregular over a period of a week or so.

fuses, check fuses first any time electrics or electronics, fail.
for ever.

double, anon posted, why?

Hi, I would check the flasher unit as well as fuses 3 and 16. The flasher may be in the fuse box. If not, check under the dash.

Just no turn signals in the back now? Maybe didn't install the bulbs tight back into the asm? No brake lights...do the lights work with headlights on and just no illumination with the brake pedal depressed? Could be brake light switch.

it should be on the fuse block.

you may have a bad bulb socket..the jeeps are known for that.

Btw, I’m available to help over the phone in case u need at https://www.6ya.com/expert/sean_54c3a3dc48a7773c

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!

Hi Bill,I think before replacing anything else you should give that hazard switch a good workout.The switch doesn't get get used very often and the contacts get corroded and can upset the indicators.Good Luck.

likely your flasher unit was failing or you had a bulb out somewhere. Flasher should be on right side of steering column under dash yours could be a "combination flasher" Older models had flashers on fuse box under dash on left side.

your multifunction switch in the steering column needs to be replaced this is very common.normally the job cost about$ 275.00

Open the hatch, there are some 10 millimeter screws on the inside. Take those out, gently pull on the whole taillight assembly. the whole assembly should come off. Then turn the light plugs counterclockwise, change the bulbs. Be very careful - these bulbs can break when you squeeze them to pull them out.
