on my 63 c-20 , when i turn the right turn signal on, both front signals flash and the green indicator doesnt flash inside the dash and the rear signals work the way the should. and my left turn signal works fine. i have no idea what could cause this because i just put a brand new turn signal switch in it about 5-6 months ago. as always, any help is greatly appreciated thanks
