Fast blinker replaced bulb works for 1/2 day goes back to blinking fast

Hi, this is Bo, an auto expert on RepairPal's Car Genius team! It sounds like you’ve got a sneaky electrical issue. When the blinker works for a bit and then starts blinking fast again, it's often a sign of poor contact in the bulb socket or possibly weak ground. You’ve already cleaned the socket, which was a great step. Check for corrosion in the socket or any loose wiring around it. You might need to inspect the ground connection or consider replacing the socket entirely if it’s worn or damaged. If you need any further advice or want help finding a trusted RepairPal shop in your area, please feel free to call us at 877-913-1554!
