2000 Chevy Tahoe Power door locks

Hi
Lock and unlock relay in fuse box. All doors out? can you lock with key?
Let me know
Thanks for donate

Yes none of the doors will lock or unlock under power, I can operate them manualy and lock them with the key. When I try the button I can hear "Click" from the fuse panel but nothing happens, also at 15 mph I hear the click (when then doors would normaly lock). Thanks for your help. Ken

O.K. ohm check Power Acessory circuit breaker in left side dash panel. or replace with another in panell.
Also relay there that is click you hear. BCM good cause it clicks to lock after a few sec.

I have a similar situation. Everything was working fine today until I went to a car wash. After this, the power locks don't work keyless or with the buttons on the 2 doors.

When I press the key fob, I hear a click under the dash and the lights flash (as they did when it worked fine). When I press the buttons on the doors, there is no click or anything else.

I checked the fuses and they all look okay. I unlocked all doors manually and pulled 30A alum. fuse in driver side block. When I replace this, the doors lock. When I tried the fobs and buttons again, same results as above.

My initial thought is something got wet and needed to dry out. Then I thought there may be a short from the water. But with the results from above, I am thinking the short would have blown the fuses. I didn't see anything under the hood that would suggest an exposed wire that the water could have touched.

Any ideas?
Thanks
