Left Turn Signal Issues

[juniormorales9]

Hello I am having issues with my 2004 silverado

 

Left turn signal does not work

Right turn signals work

Hazard lights all work

 

I ordered a flasher module and that didnt fix the issue and also checked the fuses

 

Any help is appreciated, thanks

is there power on both side of the LT fuse (there are little posts on the fuse where you can put the tester leads)?

 

or, if all the left side turn lights flash when you turn on the hazards (as well as all the right side ones), then I would consider the turn signal switch or the wiring harness to the turn signal switch has failed (ie, the problem is between the lever on the steering column and the BCM).

 

Oh yeah, I would suggest testing before throwing parts at it.  For something like this, something like the Autel PowerScan PS100 circuit tester would work well for finding where the problem is...  Well, and also having the wiring diagram for the truck so you know what wires go where...
