Question about 2012 Chevrolet Malibu
Changed fuse 3times and it keep blowing out
You have a short in the wiring of that fused circuit, or less likely that one of the mirror motors has a short. A short is an unintended path to ground, like an exposed wire touching body metal, or an internal motor failure. If that fuse is only for the mirrors and nothing else, it will be easier to find. A likely place will be in the door openings where the wires can get stretched and chafed. Pull the protective boot away from the wires where they enter the door, and check carefully. You may need to get to the mirror motors and to the switch for them. If everything looks okay, better get a multi-meter to check sections of the wires for continuity. A wiring diagram will be needed to find the right color wires that you will be looking for. I am guessing that each motor will have 4 wires to it, 2 for side to side, and 2 for up and down. These 4 wires will come from the switch on the driver's door that operates them. Power travels from the fuse to the switch, and then to the mirrors, as the switch operates them. The ground wire for the mirrors will originate at the switch, or it may be a shared common ground at the driver's master switch for the mirrors and the power windows. The short may be in any of these wires, or in the switch (evident at the connector to the switch as melted plastic, perhaps), or a short in one of the mirror motors. Good luck and good hunting.
