A1502 2015 no Wifi, new ribbon and new Wifi Module did not fix the problem

We got in a customers Macbook with the WiFi greyed out and we figured it was either the module or the possibly the ribbon that connects the motherboard to the IO board. We replaced both and tried SMC resets, but still getting WiFi greyed out..... Any ideas on what we can try next? Device is not water damaged or shows any sign of damage from the user.

I would tell the customer to wait and order one if you can. That seems like the issue most likely. Not really a WiFi power circuit on these like on MacBook Airs. Usually, bad I/O Board is the issue.

One time found broken trace on the MLB.
You can check continuity from the MLB to WiFi module pins.
Check for corrosion close to RIO connector.
