how do I change the stop light switch,do I need any special tool?
No special tools. Open the driver side door and position yourself so you can access the brake pedal. You can use a flashlight if you need more light. Locate the brake pedal switch on the underside of the brake pedal and unplug the wiring harness. Unbolt the brake light switch using a wrench, and replace it with the replacement unit. Be sure to tightly bolt the switch into place. Plug the wiring harness into the new switch. Test your brake lights to make sure they work by pressing the brake pedal.
See mrmooney's answer in your other question post. We were apparently writing at about the same time, he has a very good point
