Hoping for some direction before I start guessing with a multi meter.

Problem: None of the power windows or mirrors work at all after replacing the entire drivers side door. I tried putting the interior panel(with all the original controls) from the original door back, but still - nothing.

Background:

• 2001 Acura RL (no Nav).
• Driver's door came from '97 RL with same colors/same controls.
• I have checked all the connections and re-seated everything multiple times.
• There is no sound when I try to use the switches.
• The trunk release works fine.
• The door locks work fine
• The seat memory works
• I have checked all fuses (I think! I checked everything I thought could be related inside and under the hood

Questions:

1. Is this issue more likely some connection issue? Or could something in the door be causing it not to work. Should I put the old door back on to see if it is in the door?
2. Any general advice or how to's on how to troubleshoot?

 

I was gonna say the connection to the master unit but if it's seated then it's possible that unit is bad
