Hi; newbie here(Irishmike) I have a 06 silverado with actuator door problema, also the chevy mech. removed two relays and said that it would cost me $455.90 plus labor to fix the problem. I have no idea were the relays go, but can replace the actuator, if I have to. would anyone have an idea were the relays go?? part # 8918778 module (GM) and part # 89019320 motor? (GM)
