Hello
Recently my volvo was worked on by some repairmen and suddenly I begin to notice many electrical system failures. First, the right back signal light seems to turn into ambulance-type flashing and the service light lights up when I turn right signal light on. Then my room light burned out. Next, the electrical clock can't track time acurately. Last, my car's power lock fail to allow me to open/close all doors at the same time. Is this all caused by a simple mistake on wire connection or something bigger? Please help to make this misery go away!
