There seem to be conflicting answers above mine, so here is a link to a site which explains the organs of balance quite clearly...

The inner ear structures begin with the antrum, a cavity in the temporal bone that communicates with the middle ear attic anteriorly and with the mastoid air cells posteriorly. Mastoid air cells are a system of sinuses within the mastoid area of the temporal bone. Each air cell is lined by a mucous membrane of epithelial cells over a thin periosteum. Situated deep within the mastoid bone is a complex structure called the bony labyrinth. Within the bony labyrinth is a delicate tubular membrane called the membranous labyrinth which contains a fluid called endolymph. The bony labyrinth has three parts: the semicircular canals, the vestibule, and the cochlea. The three semicircular canals are at the top of the inner ear and sit at right angles to each other. They are generally identified by their relative positions as the superior, lateral, and posterior canals. The semicircular canals are connected to the brain via the eighth cranial nerve. They contain tiny sensory cells called crista, which detect fluid movement within the canals and maintain balance. The canals then merge into the central cavity of the bony labyrinth, the vestibule. Lying just in front of the vestibule is the cochlea, a spiral-shaped structure that contains the organ of Corti. Within the organ of Corti are over 16,000 tiny hair cells hair that transmit sound waves from the ear through the auditory nerve to the brain as electric impulses.

RE:
which part of the ear controls balance?

An organ in our inner ear, the labyrinth, is an important part of our vestibular (balance) system. The labyrinth interacts with other systems in the body, such as the visual (eyes) and skeletal (bones and joints) systems, to maintain the body's position. These systems, along with the brain and the nervous system, can be the source of balance problems.

Equilibrioception or sense of balance is one of the physiological senses, It is determined by the level of fluid properly called endolymph in the labyrinth - a complex set of tubing in the inner ear.

the mid ear or the middle area which give the controls balance .

The part of the ear that is dedicated to sensing balance and position also sends impulses through the eighth cranial nerve, the VIIIth nerve's Vestibular Portion. Those impulses are sent to the vestibular portion of the central nervous system.

The semi-circular canals, utricle and saccule make up the vestibular system and are involved in balance.

Vestibule(utriculus & sacculus) and three semicircular canals on the vestibule. These are all parts of inner ear.
