The vehicle window support apparatus provides for a user to hold a vehicle window in a desired position, relative to up and down, without the typical vehicle window support mechanisms. The apparatus does not need tools or hard installation into the vehicle. Instead, suction cups hold the window. The apparatus lower vertical member and horizontal member position the apparatus within the existing window channel of a given vehicle. The slanted member enables the upper vertical member to be proximal to the window itself, whereby the suction cups are then temporarily and removably affixed to the window, holding the window as desired by a user. Upon termination of use, the apparatus suction cups are easily removed from the window and the lower vertical member removed from the window channel.
