Default Both Windows no comm

Hello techs,
1998 coupe experiencing an issue with both windows and no communication.i cleared codes. I had extra parts, so swapped out footwell fusebox, reprogrammed another 1998 BCM, swapped out both right and left Door control modules, check all fuses. Cleaned every ground in frame (13), used a pigtail to roll both windows up and down manually, changed window switches on both sides, disconnected both door accordion plugs in door harness and checked plugs…. Any ideas??? Everything else in the car works perfectly. Also disassembled both white star connectors near the BCM…actually removed every wire out of the housing and have them making contact on ground bar, and a brand new battery…I don’t have a tech 2…any ideas??? Thanks Todd

For any "no comm" did you check powers and grounds for both modules...cleaning grounds isn't checking them..you have to "load" the grounds to check them properly.
