I have an 87 long bed with ac, and during the interior renovation process i removed the passenger kick panel where the vent is and the circular black piece has seemed to have ran off and now it won’t blow at all, but you can hear the compressor kick on but no fan. im assuming it’s because the part i removed, but i can’t figure out what it is even with the diagram. it’s my first c10 and vehicle for that matter, any help is much appreciated
