Hello, I have a 2001 Grand Cherokee 4.7 4X4. Turn signals worked intermittently and now not working at all. I checked all bulbs and the fuse...All good. So I replaced Relay. still nothing. So I replaced multi function switch. (turn signal switch). Still nothing..... My hazards have and always work. Park lights work. They even flash when I lock the jeep with my fob... I am totally stumped and out of money for this issue. Anybody have any ideas? Please help... Thanks.

 

See my sig, #1.

 

Have you replaced the flasher? It's a multi-circuit 9-pin unit that costs about $50. It's located on the top of the junction box under the dash and is a real PITA to get to. There's an aluminum brace for the steering column covering it and it can't be removed without WAY too much work! The FSM says to remove the 2 electrical plugs on the junction box and drop it down for access. I got it out with channel-lock pliers and it took me 45 minutes to get it back in with my fingers. There are 3 circuits in it; one for left turns, one for right turns, and one for the hazard warnings.
