    Dang..
    It’s pouring rain here now.
    I’ll have to attack this later.
    My garage is loaded up with my sister’s crap. She’s in-between houses.

    OP, the driver's side switch is meant to actuate the rear windows with its own 30 amp fuse, so eventhough the individual 20 amps are iffy, the main switch substitutes the rear power window switches.
    Your issue is branching out :(

    I recall when adding meso puddle pods I had forgot to reconnect window switch connector on the drivers door. The rear windows would only go down from the rear switches. Once I reconnected they worked fine. I checked ‘continuity’ at the drivers door by connecting ohm meter to ‘dead’ 20A fuse and ground. Once I toggled either of the rear window switches at the driver door the meter went from open to 6 ohms. I also took door panel off to verify any other connector issues..
    I got called to work out of town and won’t be back till late Friday.. thankfully the windows issue allows me to keep using vehicle.

    I think maybe I need to dissect that door and take a look.

    Notice how the ground for the current flow change goes through the Driver's Master switch. Also the 30 amp fuse to the Master switch to provide power when other doors switch are not used.

    Isn't there a plug inside the drivers footwell where he can check continuity through the door flex cable?

    After checking door-switches, wiring and fuses I decided to uninstall mods starting at the latest.. remote start.

    Found a bent pin on the T-harness connector. Somehow I got the pin straightened (didn’t break off)and everything works now. You can barely see it at the bottom center row on the connector.
    I figured it must have been self-induced.. :boom:
    Luckily it was just an annoying trouble, not a critical function.
    Thanks for all the help. I appreciate it!F9E3B54E-7D7A-4AA5-A081-4BECFC66D1F0.jpg
