I temporary solved the issues by changing % by AAA

function my_posts_where( $where ){
$where = str_replace("meta_key = 'courses_AAA_week_day'", "meta_key LIKE 'courses_%_week_day'", $where);
    return $where;
}
add_filter('posts_where', 'my_posts_where');

/* my query args */
$args['meta_query']=array(array(
                'key'       => 'courses_AAA_week_day',
                'value'     =>  $day,
                'compare'   => '=',
                'type'      => 'NUMERIC'
            ));
/* ... */
