Update: I had my friend that owns Michael Auto Cares in Tomball, TX. Install and program the new VSM. No change. Still no power locks and drivers door window not functioning.

So he started looking a voltages. Green wire in the wiring diagram that runs to the VSM is supposed to supply 12v to the Drivers Window and the Power locks was only showing 5v. When the power lock button was pressed it dropped to 0v. So started tracing back on the passenger side that runs along the body channel and found the green wire in the picture was broken.

Issue resolved

All power door locks not working. Had dealer install a new VSM without a diagnostic test. Still not working.
Dealer had it for 2 days then called me to tell me he would have to start charging me for diagnostics and searching for a short.

No blown fuses or relays- all are good.
No water evident at fuse box.

The original VSM was clicking and I can hear the same clicking from the new VSM when using the door lock switches and/or the remote.

Looked at all wiring harnesses inside driver door, under dash on both sides, and at both doors at hinge location. No damaged wires found.

You say you already had the vsm ( vehicle security module) replaced, but were there any codes stored in it? I believe the fuse number 30 in the interior fuse box feeds the power to the vsm, but you say that it is ok. This is an involved system which contains inputs and outputs from multiple modules, switchs, ect. It really would be your best bet to pay a pro with the correct tools and training to diagnose this issue for you. Because someone who doesn't know what the are doing can very quickly fry a module and cost you more than the diagnosis would cost.

I thought I was doing the right thing by taking it to dealer but I'm not comfortable with them.

Does anyone else have any recommendations?

I gave a donation and was expecting a better response to help with the situation.

Battery now drained down overnight so something is obviously wrong.

On mine the issue was a green wire that supplies power to the power locks and the drivers window via the VSM and I too could hear the clicking sound.

This wire was almost all the way broken. It had like a couple of strands holding it together.
Its tied to the bundle that runs along the passenger side well under the kick plate. To test that this was the issue we jumped it and everything worked great. So we spliced it and sealed. All works fine.
I did find that water was leaking. The pad underneath the carpet was wet on the passenger side where this wire bundle lives.

Best of luck
