blinker issues

My 01 tj is having issues with the blinkers. I wired in some led marker lights on my flat fenders into the blinkers, so they would blink along with the blinkers. They worked for a couple days, then I noticed when I would turn my blinker on it seemed like it was struggling to blink, like it was getting slower and weaker. Then it blew a fuse and nothing would work. Emergency flashers or blinkers.
I've replaced the fuse, flasher relay, and multifunction switch.
Current state: if I push down the emergency flasher, my brake lights will work, still no turn signals or flasher. The Wierd thing is that if I flip my blinker lever back and forth while I'm on the brakes, my rear blinkers will flash, but if I flip the lever all the way, they won't flash. It almost seems to me like the relay isn't getting power.

Does anybody have a wiring diagram for the blinker/flasher/brake electrical??

Also, my cruise control stopped working, which I assume is due to something with the brake electrical stuff

Also, I have unhooked the led marker lights, so everything is back to factory

How did you wire in the leds? The side marker lights use a floating ground through the front fender parking/turn signal bulbs, so there is no dedicated ground at the marker lights. You can find wiring diagrams here Jeep Information Center, Jeep Parts Catalog, Jeep Repair Manual & More
You will probably have to look it up under a 2000 or 2002. Check fuses first.

Not to hi-jack but I have a similar issue. When I hit the brakes, the left blinker won't work unless I push down a bit on the lever, all the way is nothing. Immediately after releasing my foot off the brake pedal the blinker magically works again. Right blinker is not affected. I have LED tail lights and LED CJ style blinkers in the front.
Taylor, you may have issue as me and I think the power is the problem. Maybe not enough is available for everything at once?

I think, in your case, it's most likely the multi-function (turn signal) switch.

I have a 2001 that I recently installed Rear LED Stop Tail Turn and back up lights. Had same problem went thru 3 different Flasher units til I found this one (Amazon.com: Jeep 2001-2006 TJ Wrangler LED Flasher Relay: Automotive)
It solved all the weird electrical problems that the LED's create. In the long run this was the easiest and cleanest way to fix this. There are other ways (putting a resistor on the + lead to LED is a option) it kinda defeats purpose of using LED's in my opinion.
Hope this helps

The led flasher and load resistor have both been used to fix the fast blink issue when using LED's. The oem flasher has a circuit that measures voltage (and compares it to voltage across a shunt) and goes to fast blink if a light is burned out. It will see led's as burned out lamps and continue to fast blink.
I used a load resistor in my tail lights for a while before going to an LED flasher, and found that not to be a great idea because of the heat generated by the resistor. I would recommend that if you are using led tail lights to go ahead and get an led flasher. I used this one: http://www.amazon.com/dp/B00KQUZHRA/...190_TE_3p_dp_1

I don't think the OP's issue is a fast blink issue.
