4wd Chassis with Mega2560, only two motors run

4WD Chassis with Arduino Mega2560 board on two robots. In both cases only the Right Front (motor ) and Left Rear (motor ) operate.

All motors work if power is directly applied to them.

My wild guess is that the motors are somehow not defined in the library.

Any help is greatly appreciated.
