2012 elantra gls no brake lights new switch fuse is new still no brake lights

Hi, I'm Chad. Welcome to JustAnswer. I'm reviewing your question and I will be posting your reply ASAP.

Hey how are you

click on link to view the switch pin out connector & BCM module diagrams

There is 4 most common issue for no stop lamp

1-Wiring or ground faulty

2-Stop lamp switch faulty

3- fuse (15 amp) blown )

4-burned bulbs

5- BRAKE LAMP RELAY ( CLICK ON LINK TO VIEW LOCATION OF IT )

,So you have done most , we have a wiring issue or missing ground, the ground is supplied by the bcm

If you do not mind me asking ,are you looking at fixing this yourself or looking to know the most possible cause of this issue and taking it to repair shop for the work ?

Do you have any prior experience in electrical troubleshooting and testing with a test light for power & ground ?

Do you have a test light & or power probe for testing ?

Please let me know

Thank You

The relay and the bcm is the most common issue ,but start with relay ,and pin out the switch connector and see what you are missing
