My front headlight (passenger side) keeps going out and my driver door is the only one that unlocks when i use the remote to open the doors. They fix it once and it only worked for a couple of days.

Typically when lights keep burning out it is because something is not grounded very well. I would check the ground wire connection to the headlight to make sure it is making a good connection at the light itself and at the grounding point. I'm not sure about the door

Sorry i meant that the light doesn't burn out it just stops working, i check the fuses and they are all ok, and as for the doors not unlocking i change the battery in the remote and the doors still don't open or lock with the remote or open or unlock using the buttons on the driver door. Any suggestions or should i take it in?
