dualshock 4 does not work with triggers

Hello, can someone faced. First, L2 was responsible for the movement of the left stick up then the stick started moving the character back - dismantled the 3D analog was replaced by petal round inside the counterpart, began to work as before, but only lasted for three days. Today alternately stopped working triggers (all), suddenly, later, L1 and L2 are reversed, and began to work R2. DualShock version 2. Can't even understand what was going on, because with rubber on them it's okay to mess up and once the chorus began, suspiciously.
PS
And Yes I cleaned it carefully).
