I also thought I would add that I just pulled the little plastic panel that contains the dead pedal for your left foot when on the highway so that I could access the fuse panel area and the associated ground wire. The ground wire looked perfect, and I removed the grounding bolt and cleaned it and the eyelet that it goes through. I put it back in and there was no improvement. Is there anything that I should check out while I have better access to the fuse panel? All the fuses are good, but is there some other connection to go after in that area. I checked every connector that I could access and, as usual, they all looked perfect, with tight connections and zero corrosion.
