2018 gmc savana no right brake/turn signal. please help me fix it.
hi. this is my first post. I need some expert help. My passenger side brake light and turn signal lights don't work. I checked the bulbs and they are all fine. I cant find the flashers and I cant seem to locate any blown fuses. please help.
some clues might be that the passenger side flasher used to flash a lot more rapidly than the driver side. then one day, the driver side started flashing rapidly too....thats about when someone told me the passenger brake light was out. the bulbs are normal incandescent type. Thanks for any help out there.

How did you test all of the bulbs?
Looking at them isn't a great test. Could you try them in a socket that works?
How did you test for voltage on the sockets?
ok So i guess I need to take the tail lights back apart and prove the bulbs work, then we can talk about it, and maybe i will find something i overlooked. i would be stoked to find both double filament bulbs bulbs are actually bad.and thats all it is.
i did the test. i took the bulbs out and tested each filament with a bench power supply. one filament was failed. it looked perfect on a visual test. you guys nailed it. thank you for all your help. cheers.
