Well, I removed the pushbutton controls from my 300D to resolder the connections and now my rear defrost doesn't work. The pushbutton controls are working fine per Ken300D's soldering instructions but I can't figure out what happened to my rear defrost. I checked the #10 fuse and it looks good. Any thoughts on this one? Is my relay bad and if so, where can I find it.

Thanks.
