As for my continuing problem. I believe I narrowed it down to a short. On the heater relay socket I have 3 prongs that are charged. Using a test light I have 2 prongs lighting up bright and 1 dimmer . If I remove the stop lamp fuse it lowers the voltage on the dimmer one. But it is not out. I unplugged the brake switch and it had no effect. Checked the brake lights and they are working normal. Hope the weather holds out so I can get to the bottom of this.
