I have an 02 A4 quattro The driver side door is not functioning properly, the windows will not roll up or down and there is no lights on the switches, also the side view mirror adjustments will not work either. The security light on the driver side door also constantly flashes.

I tested some fuses and tried doing some research but was unsuccessful any tips would be greatly appreciated. Thanks!

 

I would check the wiring between the door and the frame. It is common for some of the wires to break over time, causing mis-operations of the door mounted controls and lights.

If you pull back the black rubber cover that protects the wires, you can see the wires and determine if any are broken.
