Hey guys and gals I have a couple of questions as to what these things are. It's on a 1988 gmc 1500 2wd suburban. The black with aluminum fins is located under the column and the blue plastic thing is located behind the headlight switch. What are they and what do they do? I've never seen them before on anything before other than me and my brothers truck. Both are the same trucks mostly.
