Hyundai Elantra 2009 passenger window will not roll up

There are two fuses that cover the power windows, but if it is only one window, it is likely to be the switch, the wiring, or the motor on that particular door. An auto-electrician can diagnose. Videos may help.

Hyundai Elantra (XD; 2000-2006) fuses and relays

The fuse box is located on the driver's side of the instrument panel behind the cover. The location of the fuses in the passenger compartment: Hyundai Elantra ( ...

Did you maybe hit the window lockout switch on the driver switch control

Didn't need to replace the motor

You could have put battery voltage
directly to it & run it in either direction
by switching your power & ground feeds

The problem is a switch not working

If you had a wiring diagram, you would know where
to test for the problem

Unplug the switch & test it,if you can figure it out

Soundls like your window motor went bad. Could also be window regulator or just a bad wiring conection. Take off door pannel and check the connections and the motor. Hope that helps

The motor is a basic reversable electric motor, you provide power and ground to go one way then reverse it to go the other.
Are you getting power and ground on the wires in both directions ?

How to diagnose this problem ? Viewing wiring diagrams to see what all is invovled in these electrical circuit's , check power supply's an ground connection's using a DMM - digital multimeter !
What type power seat's ? does it have memory ,heated an cooled etc ?
Power Seats System Description and Operation
There are 2 options of power seat systems available in full size trucks. The first is 6 way driver and passenger power seats without memory. The second is an 8-way driver seat plus 4-way lumbar with memory, heat and optional cool function. While the passenger has 8-way power seats with heat and optional cool function. For the driver memory seat operation, refer to Memory Seats Description and Operation. Power seats without memory are completely controlled through the power seat switch. Battery voltage is supplied to the power seat switch through the power seat circuit breaker. While the seat adjuster switches are in an inactive state the switch contacts are closed to the power seat switch ground circuit. When a power seat switch is pressed to an active state the switch contact is closed to the battery voltage supply circuit. Each seat adjuster motor is controlled by the power seat switch through 2 motor control circuits. The seat adjuster motors are bidirectional and the direction of adjuster motor rotation is determined by which of the adjuster motor control circuits is switched to battery voltage while the other remains grounded.

If it has memory seat's there is a control module !
Battery voltage is supplied to the driver seat module through a 25 A circuit breaker. The driver seat module supplies the seat adjuster switch assembly with a battery positive reference voltage. While the seat adjuster switches are in an inactive state the switch contacts are closed to the adjuster switch common circuit.
Both right side windows have a seperate power supply from the left side window's ,has RT DOORS circuit breaker CB1 - 25amp. location left instrument panel fuse block . Circuit breaker's very rarely fail .Do the door lock's work on that side of the vehicle ? The windows won't work with their own switche's ?
The DDS controls the passenger window through a GMLAN message to the PDS. When a power window switch is activated in the up or down positions the PDS supplies power and ground to the window motor control circuits to drive the window motor in the required direction. Prior to activating a power window motor the PDS will supply the control circuit with a low current bias voltage in order to determine that a short to ground condition does not exist, and during window motor operation the PDS continues to monitor the motor current to verify proper window motor operation. (Scan tool support is available for this system)
Check PDM fuse 4 15 amp ,this supply's B+ voltage to the DOORLOCK/WINDOW switch passenger side . Check for broken wires inside the flex boot from the body to the passenger door .

The drivers door ,of course, gets worked the most. the binding is from the window regulator wearing out. they can't be fixed, only replaced. the other doors are usually the motors, from non use. As you indicated the light dims, so you are getting power to the motor, but it is locked and possibly the regulator is locked up. When the motors drags or lock, you can sometimes smack the door and get them to work again as your try to roll them up or down. also try to assist the window down as you activate it. There is only one circuit breaker for the windows.

You say that you have 12 vdc when pushing the switch to up but no voltage in the down position. Switch your voltmeter leads + and - at the motor when you push your down switch and see if you have 12 vdc then. If so then you have a bad window motor. Your up and down button switchs the polarity to the motor to go up or down.

Replace the dirver's door master control switch assy.

the switch on the passenger door is defective, replace it, the fact it (the window) works from the drivers door confirms this is the correct solution.
