Electrical problem
2001 Chevy Suburban V8 Four Wheel Drive Automatic 98,000 miles
2001 Chevy Suburban. My driver door works by pushing the lock/unlock button inside on the driver door only. My keyless option works only on the driver door. My front passenger door lock works on the driver door but not on anything else. My rear passerger doors and rear hatch aren't working at all. |

Can you lock and unlock "all" the doors from the driver's door? |

No, only the driver door its self. The front passenger doors will lock/unlock the driver door, but will not lock/unlock the its self. And again the two rear and rear hatch don't do anything. |

Everything points to the "body control module". I can't believe you would have 3 bad switches or 3 bad actuators or a combination there of. My cut and paste is down, but if you have access to a fax I can send you a wiring diagram. |

Mike, there are 3 different lock systems used in your suburban. One is ruled out because you have remote entry. Narrowing down the remaining two. Do you have a lock switch on the driver's door control that will disable the rear door lock systems? Also, on your keyless remote, if you push the button "once" does it unlock the driver's door only and have to push it again to unlock "all" the doors? It may not work that way now but, is that the way it is supposed to work?
The body control module is under the left side of the dash by the steering column.
Again, if you have access to a fax, I'll send you diagrams so you will know what I'm talking about. It may just be a relay and not the BC module.
One more thing, if you try to lock or unlock the right rear door from the driver's door, do you hear anything from the RR door? |

No, there isn't anything on the drivers door to disable the rear locks. As far as the keyless. Yes, pushed once will lock and unlock the driver door. Before the my problem started, yes a second push would unlock the rest of the doors. One other thing it may or may not be cause of the problem, but I was haveing problems with my battery around the time the lock problem started. I have since replaced the battery and no more problem with starting my vehicle. Could there be a problem with the automatic lock needing to be reset? My fax is #360-944-3019. Thanks |

Disconnecting the battery will not affect your lock operation. As far as reseting or re-programing the system, the reciever is getting the signal from the remote because it will open the driver's door, so that part is ok. Everything points to a bad BC module. Faxed diagrams are on the way. |
