Rooms above garages are infamous for being too cold in the winter and too hot in the summer. More often than not it's due to improper insulation between the garage ceiling and the room above's floor.
Also if you have heat ducting inside that space it is negatively affecting the heating / cooling of that room .
Removing the ceiling in the garage more than likely you will fing batt insulation that is poorly installed.
Removal of that batt insulation and 2lb spray foam applied to the underside of the floor above --- ensuring that all connections to exterior surfaces are also sprayed along with any ducting will provide a superior insulated system.
An important point mentioned --- the spray foam also provides an air tight seal preventing carbon monoxide ( CO ) from the garage entering the room above.
