Francisco,

What light are you referring to?

Customer: replied 10 months ago.
Inside the truck , I meant passenger side and driver side the light is off.
Expert:  Ron replied 10 months ago.

Are you referring to the courtesy lights?

Customer: replied 10 months ago.
when I open the door the light is off.
Expert:  Ron replied 10 months ago.

Have you checked the #8 (10 amp) fuse located in the interior fuse panel to make sure its not blown and has power in and out of it?

Customer: replied 10 months ago.
Yeah , l checked all fuses , with the test light bulb , and I replaced with new fuses. But it doesn't fix it.
Expert:  Ron replied 10 months ago.

Okay the courtesy lights are controlled by the BCM (body control module) and in order to determine what is causing this problem if your sure the fuse is okay will require scanning the BCM to see what the fault code and or codes that should be setting when the lights do not come on. Are you able to scan the PCM and get me the fault codes?

Customer: replied 10 months ago.
I don't have BCM or PCM. Where I can buy it?
Expert:  Ron replied 10 months ago.

You dont buy them, your truck already have them, the BCM is the module that controls the lighting and the PCM (computer) runs the engine control system. You need to scan the BCM to see what the fault code is that it should be setting when the lights do not come on.
