My heat/ac blow little air even at high setting. Like the high setting is about half of what a function car would be. Is this a concern or all of these cars like this? It barelyblow anything out at the lowest setting.

Is there a filter or screen to clean?

 

Probably a piece of trash or something in the return air vent of the hvac. The return air is where the air goes back INTO the fan to get cooled then blown back out, they're usually somewhere underneath at the floor panel somewhere.

 

dude, fbods dont have an air recirculate feature, so why would they suck in air from inside thecar? If they do where is the vent..
