2000 Chevy Suburban: all of the relays and I..unlock..drivers door

Resolved Question:

The power door locks on my 2000 Chevy Suburban have stopped working.
I replaced all of the relays and I now have the driver door lock working and the unlock works on all doors. The remaining door will not lock from the drivers door, the remote or at the door itself. All three have the same problem. Is there possibly another relay or fuse that I have missed.

sorry for the delay, but your question is a little confusing

>>"I replaced all of the relays and I now have the driver door lock working and the unlock works on all doors. The remaining door will not lock from the drivers door, the remote or at the door itself. All three have the same problem."<< ??

 

The "remaining" door? (which door)
"All three have the same problem" ?? (what does that mean)

 

There are 3 Relays:
1 for Driver Unlock
1 for All Doors Lock
1 for All Doors UnLock

 

If the Drivers door functions properly (lock / unlock), check for broken wire in Driver Door Boot / Kick Panel Harness (harness that goes into door from kick panel)
WHITE wire
UNLOCK RELAY (in Fuse Panel):
Check for Ground on WHITE wire at Switch & UNLOCK Relay PIN 85
Check Voltage on PIN 87

Check Ground on PIN 30

 

If check are good, Replace Relay
