Custom Post type Query by Taxonomy

Question

This has been driving me nuts for hours. I've checked numerous pages on the web for an answer but I can't find one. I'm trying to get all of the posts from a custom post type, that are attached to an array of taxonomy ids. Here's the code

        $args = array( 
            'post_type' => 'contractors',
            'showposts' => -1,
            'tax_query' => array(
                array(
                    'taxonomy' => $taxonomy,
                    'terms' => $taxarray,
                    'field' => 'id'
                )
            )
        );
    $query = new WP_Query($args);

If you're wondering about the variables...

$taxonomy="service_type"; //and yes, this exists
$taxarray = array(24); //and yes, this id exists, and yes it has custom post types attached.

Basically, when I print_r($query), no posts are returned. Of course, I see all the other junk that spits out of it, but there's no posts. I'm pulling my hair out over this.

EDIT: I don't know if this is helpful, but a couple of things should be noted. I'm trying to do this inside a custom class->function, and I'm on the latest wordpress, and php 5+.

EDIT #2: New pastebin with fuller code: http://pastebin.com/px9N4LCV

FINAL EDIT: I figured out why it wasn't working. I was running the query too early, and Wordpress wasn't recognizing my taxonomy yet.

I think showposts was replaced by posts_per_page in wordpress 2.1. See pagination parameters. Also note that print_r($query) won't return any results because $query variables is WP_Query object; you need to exceute the query.

$args = array( 
        'post_type' => 'contractors',
        'posts_per_page' => -1,
        'tax_query' => array(
            array(
                'taxonomy' => $taxonomy,
                'terms' => $taxarray,
                'field' => 'id'
            )
        )
    );
$query = new WP_Query($args);
$results = $query->get_posts();
print_r($results);
