Even a woodworker should have a multimeter, and with one, your problem is fairly easy to trouble shoot. There is a possibility that you have a switch problem and need lube in the regulator for the driver's side window. I also have a hunch that the passenger side might be wiring, a bad connection or a bad motor.
Open the hood and find the 2 wire connector just ahead of the driver's door hinge. Pull it apart and hook up your voltmeter to the connector coming from the car(not to door). The meter should read approx +12 or -12 volts as you move the switch from up to down. If voltage is very low, say < 6 volts, pry the console window switch plate up to get to the switches. Put the passenger switch in the driver switch slots and see if voltage is up to +/- 12 volts. If so, you need to clean the driver side switch or replace it. The switches can be carefully pryed apart and the contacts cleaned with a small file or emery cloth. I would still pull the door panel and lubricate the regulator mechanism and spray the window guides with silicone.
If you did get 12 volts at the door connector, then you have to check the wiring and connectors to the motor in the door. Remove door pull handle and small panel and then door panel to get access to the motor. If you get 12 volts at the motor when you push the switch, but no motor movement, the motor is bad. Rebuild is possible, but I would just get a new or used one from sobstory(a site sponsor). If no 12 volts at the motor, but you got 12 volts at the door, then replace the wires from the door connector to the motor and recheck the motor.
For the passenger door go through the same procedure to pin down the problem. You might just need to clean the switches and lube the window mechanisms. Either way, don't through money at parts until you have it figured out.
