What type of codes does it throw?

i dont even know how to check the codes.could i do it myself.

Yes you can check for codes by turning the key to the first position (don't start the car) and pressing the off & warmer buttons at the same time. Write down the codes and then post them here.

the current codes are 0139,1139,1312,0061?

P0139 Heated Oxygen Sensor (H02S)Slow Responce Bank 1 Sensor 2
P1139 Heated Oxygen Sensor (H02S) Insuff. Switching Bank 1 Sensor 2
AC1312 A/C High Side Temperature Sensor Open Circuit
