Answers :

Stop Lamps\012
\012\012\011 The body control module (BCM) is responsible for controlling the stop lamps. When the driver presses the brake pedal, the BCM will receive a signal from the brake pedal position sensor. The BCM then supplies battery positive voltage to both left and right stop lamp assemblies and to the center high mounted stop lamp (CHMSL). The stop lamps are grounded at G401 and G403. The CHMSL is grounded at G302.\012
\012Did you check the blub , is there power ( B+) at the third light ? Is the ground G302 good ? Do you have a DVOM - digital volt ohm meter , do you know how to use one ? Do you know what voltage drop is ? an know how to test it ? Check the stop lamp relay in the under hood fuse / relay box.
