Sounds like the blower motor is going out. and need full voltage to run. Are you might have leaves or trash in the duct work causing to motor to drag at low speeds, and making it make the noise that it is making.

you need a tool to measure high pressure. you can also make it by yourself.
when you have tool and proper fittings (same diameter with spark plugs) you will need to remove fuel pump fuse. you will remove all spark plugs. you will screw your pressure gauge to one of spark plug holes. someone will cracnk engine(but it wont work of course) you will record pressure value you read on gauge. and you will try on all cylinders same way and you will compare results. all cyclinders must be read close to each other.
sounds like you may need to look at the compressor under the hood and see if the wire on it is plugged in and make sure its not cut or broken. the squeak could be due to a loose belt try tightening it if it is possible
