Hi , i have a 2004 FLSTC/I, i have a problem with the left blinker not working front and rear ,the front marker bulb was burnt out so replaced ,the marker does come on,the rear bulb is good ,checked all the wiring and all seemed good,any advice or ideas what to try next,thanks in advance

 

Sounds like a ground issue but it's not an easy task to find it. A test light and a lot of patience is needed for this one.

 

What is it actually doing?? Or not doing??

 

sorry, its not blinking when turning signal on ,front or rear left side ,clutch side

 

i know this sounds crazy but i had the same thing. the bulb was incorrectly in the socket. there are 2 pins, u can actually get the bulb in both ways, however u will notice 2 on either side of thr bulb, one higher one lower, try half turn.

 

Swap out the right and left side bulbs to double check that it is not a bulb problem. If not a bulb problem, check all fuses and relays, especially any that were installed in-line... while doing this make sure each connection is tight and has dielectric grease on it for weather proofing. These two steps correct 99% of turn signal problems... if still not working, it's time to bypass the wiring harness and run new wires... one of the wiring harness wires may have separated.

 

If this doesn't work get a multi-meter and check it out. Start from the bulb housing and work your way back to the switch.

 

fixed Hi ,it ended being one of the pins on the blinker wire was not pushed in all the way in the connection ,thanks for the help

 

Like the above poster said ,the bulb is upside down,had the same problem
