Why no power right side and there at the left side?
Did you test for power or is it that the head light is not working? I would trace the wiring from the right to the left starting at the right head light. Also if you left head light is not coming on and you find you have power to the light, check that the light socket or plug is clean and check the ground wire for that light! If you find the wire running to the light is not getting power you will need to check the wire itself and the point where it connects to the right head light, normally at the back of the light socket.
Trouble shot heater switch and blower moter
You don't give much info, so it's hard to give you a good answer. Do you have power up to the heater switch and after turning the heater switch to the on position do you have power to the blower? Did you check the fuses, do you have power on both sides of the fuse? if you do follow that wire and check for power at the other end of it. Some cars have a temperature sensor and the blower will not come on until the temp. is warm enough so that the blower will not blow cold air. If you track the hot lead from the fuse box to the switch, through the switch and to the blower and at any point find you no longer have power, that would be the component I would think is causing your problem. You can also check the blower by running a test lead from the positive side of the battery to the blower motor and see if it runs.
