When i bought this truck the rear door locks didnt work. i replaced the lock actuators, once i reconnected the battery and tested them out i had smoke coming from both back doors. obviously i melted both lock motors. now, after checking the wiring and voltage at the connector i am getting 12v at the gray, blue/black, and orange wires. i called a local gm specialist and was told this should not be the case. ive also noticed that none of the controls on the left side of the steering wheel work, but the right side works fine. im trying to find the bcm pinout so i can start disconnecting plugs and try to narrow down where my problem is coming from. could it be the master door lock switch? the rear doors didnt work with the switch or the remote. any input would be appreciated.
