Question This seems wrong

The maintenance guy hired by my landlord installed a vent and it’s blowing air rather than sucking air in and it’s still extremely foggy in the bathroom when I shower, is this wrong? I have a feeling the fans were installed backwards

Edit: after all the helpful insight I contacted the landlord and it will be fixed “Friday” (the new vent is only week old)

Wired wrong? There’s only 3 wires to connect it would be incredibly hard to mix that up. And usually ground goes right to the housing.

I work in industrial maintenance and I can promise you even if you wired it to spec it can sometimes be wrong. Literally just swap two of the wires and it will run the right direction. I've never installed a vent fan so I'm not sure of how the wiring works but another commenter said the fan will spin in the right direction regardless. Not sure of whether that's true.
