The fasteners look like an allen head with a pin in the middle. Looks like you would need an allen wrench with a tiny hole drilled in the middle of it. Any ideas what/where I could get a tool like this?

@toolbag it sounds like you are talking about the tamper resistant Allen screws. It is a security feature that is easily circumventeed wit tool kits like like these. you can get those for Torx as well as many other screw heads.

I have got the screws out but the unit still seems to be sealed. I gave a new lower hose duct to replace the spilt one but now at a loss as to how to get to it.

Any body know exactly what size tool to take apart? Have tried every size and can’t get it apart!!
