My power windows have not worked for awhile and i checked automatic fuse for continuity and even bypassed the fuse, still all four power windows do not work. and to make problems worse, the passengers window remains down and does not move...... any help?

Check for supply voltage to the actuator switch. If there is voltage TO the switch, activate the switch, and test for voltage on the switch output. If there is no voltage to to the switch, trace the issue back to the fuse panel. If there is voltage at the switch input AND voltage at the output of the switch, continue...
Is the vehicle equipped with an "express" automatic window mode? If so, check to be sure the microswitch on the regulator is functioning. Also, verify that the automatic module (located in the armrest) is operating. Continue...
When the actuator switch is operated, check for voltage at the motor. If there is voltage at the motor, make sure that the regulator mechanism is not jammed. (Has it been lubricated in the past 10 years?) Continue...
If the actuator is operating and the regulator mechanism is operating correctly but the power window still does not work, replace the window motor.
Power window usually don't have a fuse but an automatically resetting breaker. If all four windows stopped working at the same time check the body control module that is what manages the power windows. Good luck.
Change the battery in your wireless remote control. Check the fuses located underneath the drivers side steering wheel, flip the fuse box cover lid over and replace the power window and power door lock fuses. The back of the cover lid will have a diagram showing where each fuse is located, replace with the same number amp fuse. If your fuses are good and the battery inside your remote is new then you will need to replace the drivers side power window switch, click on the link below to view a replacement:
Sounds like a fuse problem. Check your fuses. If you need help find the exact fuses for power windows, look in your owners manual. In many cases, they can be in the engine compartment or the drivers kick panel. If you cannot tell if a fuse is blown, use a volt meter set to check continuity. If the voltmeter reads 0 or .1, the fuse is fine, if it reads 1, the fuse is blown. Hope this helps
If you are sure the fuel pump relay is working, check continuity from the pump to the relay socket. These wires love to corrode. When you turn your ignition on, the fuel pump will only run for a couple seconds before it shuts off via the automatic shutdown relay. Make sure you are checking power within this window. The PCM (powertrain control module) is what completes the ground in order for the relay to send power to the pump. If the PCM does not recieve a signal from several sensors (mainly the Crank Sensor) it will not turn on the pump. You may want to check these sensors, is the check engine light on? You can scan it to see if any sensors have thrown a code. Be sure all applicable fuses are ok, the PCM may have its own fuse, check that even if the fuel pump fuse is ok. Your Truck may also have an inertia switch for the fuel pump which shuts it off during an accident. Check that as well.
