So here's some background on the issue.
My Impreza's driver side turn signal is very dim and will sometimes hyperflash erratically. I've tried changing the bulb and cleaning up the contacts in the socket and neither fixes the issue.
My Subaru mechanic told me that this is a common issue with this model year and the socket most likely needs replacing, im no longer within range of my mechanic so I was wondering if I could do this myself.
Unfortunately the socket type is not like other Subaru's where it can be easily snapped on and off. I've posted an image. What might be the steps to fixing this, as a last resort do I need to head over to a dealership?
