I have a 1998 passat, when i have the back passenger door power plugged in besides speakers, and lock the doors, it will not recognize that the door is lockedd and the alarm will start going off. I have checked all the wires inside the rubber boot where the door closes, and I cannot figure it out. Also, when you lock it the dome lights and map lights over the back doors blink. Any help would be very appreciated. Thank you!
