Help please! I dont know a whole lot about wiring and my turn signals have quit
working on me, they flash once and stop working, does any one know what the problem could be or trouble shooting i could do to solve the problem, i drive a 99 cherokee sport

 

try changing the flasher relay

 

I'm having a similar issue with my 2000 Cherokee as well. I've put in 2 relays and even changed out the switch. Mine will blink a few times and quit. It happens in both directions, however the flashers work perfectly fine. I think there is another problem. I'm going to check fuse #12. I've kind of run out of options.

 

usually with electronics if it works a little then quits, something is heating up and failing, or you have a bad ground...see if you can get a diagram . If you find one post it.

 

i have a 2000 grand cherokee ,turn signals dont work..... any idea where the relay would be??? i read on another post the ground for the rear lights is under the the rear driver side door sill, im gonna check that

 

check the headlight delay relay...it can cause the tail lights/ headlights to do some crazy stuff when it's bad.
