weird turn signal problem.

[sctur601]

Hi all I am having a poblem wih my turn signals on my 90 yj. The right turn signals work fine, but when I turn the left ones on both rear tail lights blink, but the front one works properly. I have checked grounds and such and everything seems to be ok. has anyone here had a proplem like this? Could the switch be going bad?
Thanks
Shawn

Same think on my XJ. From the research I have done it seems to be the flasher module. Good luck.

Yes, check the module/switch...
