Turn signal issues

i have a 2001 volvo v40. in the last year, i have had to change the front driver’s side directional/turn signal bulb multiple times after the bulb would just stay on and not blink, with the rear driver’s side directional blinking rapidly, as with the light in the car. when i had changed the bulb previously, all was well. today, i purchased new bulbs and noticed not only was the bulb i replaced fine, the new bulbs acted in the same manner (on, no blinking). fuses are fine, wiring appears good. any ideas? thank you.

Step 1 is to double check you have the right bulb and it is inserted correctly. Next step is the check the socket for any signs of trouble and may require replacement. Look inside the socket to see if something is bent out of place or corroded.
