Up early doing my homework......there are several mechanisms inside the door that people discuss. You have told me it is the door handle switch which makes sense. I watched the vid you included which just showed a close up of the part and a circuit board....but when I search ebay for this part I keep getting a micro switch cable thing........So I am guessing by the pics in the vid...this cable attaches to the part with the green board that might have a bad solder connection. Is that correct? If so...the part in the link I will include is not what I need then ...right?
