Thanks Tiny. I believe the driver side horn is the only one with rust on the connection where it goes into the horn, but when this post started I sprayed pb blaster on the screw to loosen it up so if I did need to get it off and clean the connections/take apart the horn I could do it more easily. I know my grounds are good because when I took the bolts that hold the horns off the area where the bolts were was shiney.
