Door sensor

I think I have a faulty door sensor. Sometimes when opening the driver's door no lights or anything turn on but if you kick the little sensor on the door the lights will click back on. It only does this sometimes...Does anyone know where I could buy a new switch? Or would it even be the switch(possibly faulty wiring etc.) Thanks

I would just go to the junk yard and get one, I don't think that is a common problem with these cars. So one from a j-yard should be fine.

Try lubricating the switch that might just be the problem.
