Well my 76 D100 turn signals do not work right. The right side blinks but very slowly and the left side only blinks if I do it manually by hand every few seconds. My hazards do not come on at all unless I turn them on and turn the turn signal at the same time. I am thinking turn signal switch but before I order it I wanted to see what you guys thought. Also what do I have to do to replace it. are there any special tools I will need.
