2005 Silverado power door lock will not unlock !@#$

[appelingogt]

The power function works properly when you lock it both manually and with switch, but the fucker will not unlock unless you manually unlock it...door latch, lock actuator and master drivers door switch have been replaced. Ive searched high and low, cant get wiring diagram, not visible broken wire or chaffing anywhere...anybody seen this???

I'm going to state the obvious since I did not see it mentioned.

Have you checked the fuses and relays?

Have you tried using your spare key FOB?

If you've tried all of that there might be an issue with the BCM.

My Tahoe wouldn't unlock with the driver master switch. turned out the switch for the child lock thing failed even though I never used it. replaced it and was good to go.

Grab the harness in the door jam and move it around while hitting switch. They tend to break in that area
