I want to add a manual fan switch also, I've heard is much better and keeps everything way cooler

So I pumped the brakes until the low air warning came on... and the fan doesn't turn freely but it still moving. Is it supposed to move at all or no?

No, you most likely need new fan clutch. Should not cost more then 1k
Ladytrukr Thanks this. -
If it running hot you need to have it looked at very soon.
Good luck post what happens please -
just turn on ac while on idle with hood up and yoiu should see fan cycle on and off if working properly, either your radiator is blocked or you might actually need a thermostat.

Should she ba able to spin fan when its engaged?
Ladytrukr Thanks this. -
Bleed down all your air pressure with the engine off then try and spin the fan.
If it spins by hand with no air pressure it's got a dead fan clutch.
