So I have a 2003 tl-p, and recently the turn signals stopped working on both the inside and outside of the car. I checked the fuses and replaced the flasher relay, however the problem persists. There is no clicking sound from the flasher relay when I engage the switch. I do not want to buy a new turn signal switch if I do not have to, is there any way to tell if it is in fact the switch or not?

 

install the spare fuse of that rating and test again,,spare is stored in fusebox

never think you can tell one of these micro fuses is good without a test meter

is there power at the fuse port?

you can buy signal parts used if needed,, dont hear about them wearing out --
but it can happen,, if you are a really good driver and signal all the time!

 

is this since you did the switchbacks? ck all the ground wires for those

 

Ok thanks I will check those and report back, the switchbacks have been done for over a year so it shouldn't be them. However the led switchbacks do seem to need replacement more often than I would have thought, they flicker and go out after only like 5-6 months.

 

sounds like bad ground to me

 

so here was the problem..checked all the fuses and the ports they went into. checked the ports the flasher relay went into, & turns out that the flasher unit that i had purchased from the store was faulty. sucks, but at least it wasn't anything too problematic. thanks a bunch for your help bro.
