I need a wiring diagram for the door lock system on my 99 suburban lt. My door looks do not work properly and it has been suggested that my ground or power source may be at fault. the switches do not work right from either side and only the left rear lock works. Once every 10 trys they all work. Any help would be great. Thanks

IT IS NOT NECESSARY TO GRAB THE:

LT BLUE = LOCK / WHITE = UNLOCK IN THE BOOT OF THE DOORS.

IT IS MUCH EASIER TO GRAB AT THE RELAYS. STICK YOUR HEAD UNDER THE DASH. IF YOU LOOK TO THE RIGHT OF THE STEERING COLUMN KIND OF NEAR THE FIREWALL (ABOUT 6 INCHES FROM FIREWALL) YOU CAN SEE A GROUP OF WIRES TAPED UP AND YOU WILL FIND THE WIRES RIGHT THERE. ITS STILL GOING TO BE THE SAME COLORS...IN THE GROUP OF WIRES THAT GOES TO THE RELAY, YOU WILL FIND A LT. BLUE, TAN, GRAY, TAN, AND WHITE WIRE.

THE TAN AND GRAY ARE MOTOR WIRES. YOU WILL WANT TO TAP THE LT.BLU AND WHITE WIRE. ITS NOTICEABLY SMALLER THEN THE GRAY AND TAN WIRES.
