hey, well my parking brake light doesnt come on when u pull the handle i took off the center console and everything seems fine. i got a tester and it seems that switch works on GROUND electricity? i tested the bulb and it works well. how can i check the wiring?
 
When the switch closes, it shorts to ground. If you short the purple/white wire that runs to the switch to ground and the lamp comes on, then the switch is bad, or is not being pressed enough, or has a bad ground connection.
To check the wiring, you will need to unplug the connector to the instrument cluster and then measure the resistance (or verify continuity) of the purple/white wire from this connector to the other end at the parking brake switch.
