Tail lights not working but brake lights and turn signal lights do

Hi, this is Bo, an auto expert on RepairPal's Car Genius team! Your Blazer sounds haunted, and it's not even October yet! For the taillights, start by checking the fuse box for any blown fuses related to them. If the fuses are good, inspect the bulbs and wiring for damage. Sometimes, there are dual filament bulbs, and the brake light filament may have burned out. it would be weird if both went out at the same time, but it's not impossible. The gauge lights and gear indicator sound like a loose connection or bad ground. Gently tap around the dashboard to locate where it flickers. A loose connection needs tightening or repair behind the dashboard. If unsure, a mechanic can diagnose and fix these issues efficiently. Good luck busting that ghost!
