Hey eyedoc, got a question about my vent air blower in my 2006 tacoma. Do I need to remove the 4 bolts AND the 4 screws? Or can I just remove the four inner philips head screws and leave the outer ones, I am assuming those are holding the panel that allows access to the 2 gold adjustment screws. I really want to handle this myself, even though I am covered under warranty, the dealer ordered the blower and sound kit, but it will take a month and a half due to backorder.
