Sills

I was going to post under small questions however realized others may have this issue so started a thread. I have a 97 s14 Silvia, Rb swapped with a ws pro harness however it did this back with the stock Sr aswell towards the end. Left hand signal works perfectly, When I use the right hand singal its always a surprise what happens. Either it will work properly, which is the least likely thing to happen... Sometimes it will flash quickly as if a bulb isnt working, or most commonly when I got to signal nothing happens at all. The right signal light on the dash will also glow a dim solid green without flashing and usually will stay lit even after the collumn has returned to the middle or even when im signaling left. Please help me figure out what to look for. Ty in advance.
