Passenger door won't open.

All four door speakers quite working and now
Also radio lights up but know sound.

Steering wheel is locked & can't turn the key to start the car.

My drivers side rear remote window will not work either on the door switch or the main panel switch I took it into a local repair shop they tried replacing the motor, with regulator master switch and… 

The steering wheel suddenly tightens. Occasionally, I turn of the engine and start it again and it will start working properly. It does not seem to have a power steering fluid deficit. Any advice?
