Maybe your power source can't manage all circuits.
What is your power source's specs? (voltage and current)
Yes I agree with you luciferus. But it depends also to the external load @ o/p on uc, that may be drawing more current. I think sk8ter87 have to check the driver ckt once again(i mean the rating of the driver).
Got short circuited somewhere or loose soldering of wires connected to the controller/supply?

the voltage is around 1v compare to at least 3v
by the way,i'm using 9v as my power source...
Where comes 3v? If you are powering with 5v to the pic then the output on the io should be 5v unless you are using pwm
what is your motor rating? Its may be more as compare to the supply. I think you have to increase the power....
Nandhu015..
sorry bro..may be i got wrong info about the 3v..
but our problem,we only able to perform 2 of 4 operation at the time..
the other 2 operation is working,but the motor rotate very slow..
hope you can help me..

hmm..but the power required for the pic only 5v only..
I dont think ucsam its of pwm problem because the motor is rotating but it is slow. Hence it may not be getting efficient power from supply. If sk8ter87 can provide the circuit diag it will be more clear.

& 5V is not power
can you post your PIC16F codes here? There seems to be something wrong with what you are doing. May be your sequence is wrong in driving the H bridge?
