Probably a broken earth wire in the loom from body to the door.

Check the wiring in the cable trunk to the door not unusual to find one or more wires with cracked insulation or completely snapped

You might be lucky and be able to see it is broken.

Often in the loop between the car body and the door

It's also possible that the problem is with the wiring loom to the driver's door. The functions of the passenger door are often operated by controls on the driver door, some of which are duplicated on the passenger door and the driver's door loom normally suffers much more flexing over the years than that of the passenger door.
Depending on design, there might also be multi pin plugs and sockets in the 'A' pillars, where the door looms plug in, and these can suffer from corrosion if water gets in.
