Please explain about this program

[wafagenius]

The PIC is running,it have power,there is a reading on ADC,there is no error message while compiling.However after burn it to PIC only one of the motor working.I have no idea what is going on. in configuration bits the setting is "oscillator is HS mode" and "watchdog timer is ON" and other configuration is off.I have attached the circuit,I really need help

I looked at the code and it seems that if one wheel is turning the other should too, codewise. I think you have an electrical problem or perhaps a bad servo.

Try swapping the left and right servo connectors to see if it's the actual servo that doesnt work. If the one that doesn't work now start working when you swap places it's either something in the code or a bad connection on the circuitboard. Do you have 6V and GND on both servo connectors?

It can also be a bad pin on the PIC, can you try moving the servo control lines from PortC.0 and PortC.1 to PortB.0 and PortB.1 for example. Don't forget to change the code accordingly.

Thanks anyway MR HenrikOlsson due to your explaination. I really appreciated it. I will look into what you have suggested.

wafagenius,
Addition to other's suggestions: Tie all unused PIC pins to ground or power, do not allow pins to float, many strange and unwanted things occur with open pins.
Your schematic shows many unused pins.

Thanks Bro for the suggestion.
