Welcome to this forum! I've renamed your thread, and moved it into the Ranger section. Did you check the ground connections?

 

[poorboy58]

no i havent where would they be located

There should be a ground wire in the rear wiring harness which is connected to the body. The brake switch has to complete the circuit. Do you have a schematic diagram?

 

[poorboy58]

No, I don't have the wiring diagram. There is fire coming out of the brake light switch!

It sounds like you have a short. This short will ruin your brake light switch. I don't know why the fuse didn't blow.

does anybody know where the light control module is located on a 2002 ford rsnger xtra cab

The brake switch are very bad on these vehicles. I would just replace it, Autozone got it under $10 for a new one.

I would wire a headlight in place of the brake switch. This will power the brake lights on all the time and allow you to diagnose the short. The headlight will be bright and you can wiggle around wires till you find the short, making the lamp dimmer. Nice thing about shorts is they usually aren't solid connections. A little movement will cause them to unshort. That indicates you are close and can then hone in on it. I always have a couple headlights around with one element burned out.

I have been trying to fix my neices truck without any luck. I am not a mechanic but good with directions. Where did you locate this? She has the third brake, but no rear brakes. They said it was the BPP, but it is still doing it. I tried tracing wires, but I am lost. The BPP give me almost 12 volts. I can't find anywhere else to test. Nothing coming back to the brakes though.
