2000 Chevy Tahoe Power door locks

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

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
