So I have an 2004 fx4 and I put led bulbs in both the head and tail lights and I know they blink faster with led bulbs but my passenger side blinker will most the time not work. If I turn my right blinker on it just turns on and dosnt blink, I don't know if it is a relay or fuse because it only dosnt work for the right blinker the majority of the time. Any help would be great, thanks.

 

Did you put an LED flasher in when you converted the bulbs?

 

No just the led bulbs and they were working fine( just blinking fast) but the right blinker just turns on instead of blinking

 

Put an EP27L flasher in it and see if that fixes your problem.

 

Have you checked your blinker fluid?

 

Yeah... sounds like the right side blinker fluid is low...
