I'm hoping that someone here can give me an idea of what happened and how I can fix it. (I have a 2004 LJ)
Here's what I did: I replaced my front running lights / flashers with LED bulbs and had the fast flashing problem. I put the stock bulbs back in and went to AutoZone and got an EP-27 flasher module. I removed the stock flasher module from the steering column and installed the EP-27 module. I hit the Emergency flasher button to test it and all I got was a buzzing noise for a few seconds. I replaced the OEM module and now I get nothing from the turn signals, emergency flashers, or brake lights. I've checked the turn signal fuse (#13) and the brake light fuse (#2) and both are Ok.
What am I missing here? Is there a fuse somewhere that may have blown? The fact that the EP-27 buzzed for a few seconds and then quit leads me to believe that it may have been a fuse.
Any help would be greatly appreciated, thanks in advance for your replies.
