I need to replace the switch that my turn signal lever plugs into. I see that it has a small wiring harness going down to the base of the column. I also noticed that its all one piece. Does anyone know what this whole part is called? Ive tried stores and a dealer and they dont know what Im talking about. My blazer is an 89, so the problem is that my wipers wont work because this part froze up. If I had a name, maybe someone would make some sense of it.
