Custom Module Layout Not Working in Magento 1.7

I've been fighting a while with a problem, but I can't find a solution.

Here is the thing:

Got a module that I need to show in the sidebar of catalog product view so this is my module.xml in default/default/layout/module.xml (module.xml is fictional name)

garantiaextendida.xml:

<?xml version="1.0"?>
<layout>
<catalog_product_view>
    <reference name="right">
        <block type="garantiaextendida/garantias" name="garantias.banner" template="garantiaextendida/banner.phtml" />
    </reference>
</catalog_product_view>
</layout>

config.xml:

<?xml version="1.0"?>
<config>
    <modules>
        <Felisiakluciano_Garantiaextendida>
            <version>1.0.1</version>
        </Felisiakluciano_Garantiaextendida>
    </modules>
     <admin>
        <routers>
            <garantiaextendida>

                <args>

                </args>
            </garantiaextendida>
        </routers>
    </admin>
    <adminhtml>
        <menu>
            <garantiaextendida module="garantiaextendida">
