check yoru fuses first and then seeif button is sending power to mirror. pic attached where they are it could be a switch or the motor in the mirror as well

Thanks. Fuse blew. Changed and then blew again when used switch.

then either the motor is bad a wire is making contact with the body someplace. if you disconnect mirro motor connector and try switch that will elilmnate motor aand if fuse blows you know it'aharness problem or switch problem

Thanks.
