Power Window Relay

Where is the relay for the rear power windows located on the 2003 wagon?

No where. There isn't one. What's the exact problem?

Rear left window would not go up. Reversed the 2 wires to the motor and then it went up. Left them disconnected so it wouldn't happen again.

So you've, in effect, tested the window motor. My suggestion would be the window switch contacts are dirty, the window control switch has failed or the wiring controlling the "up" direction has an open.

I think you're right. Since neither the master switch (by the driver) or the local switch work, would it most likely be the master switch?
I think there is no open since there is only 2 wires going to the motor, if one of those wires were open it wouldn't make a circuit (wouldn't work in either direction).
Since there is no relay, what are the boxes that are about an inch or so square under the dash near the fuses and under the hood with some other fuses (just curious)?

Other way round; check the local switch first. You're getting power to the local switch since moving the wires at the motor worked the motor and power flows through the switch. The circuit is laid out like this:
Fuse - wiring - master switch - wiring - local switch - wiring - window motor.

Usually test components by working from the non-functioning part (the window motor) and work "up the chain" in the circuit to see where the power gets interupted. You've already confirmed the window motor works.

One wire controls the "up" function; the other wire controls the "down" function. At the local switch, the "inbound" yellow/blue wire to the switch connects to the "outbound" yellow/red wire to the motor and controls the down direction.
The white/blue and white/red wire combination controls the up direction.
The switch is grounded.
So it's possible one contact in the switch is dirty or corroded or a single wire is broken.

I didn't say the car didn't use relays; I meant there were no relays in the circuit you are interested in. The relays in the "fuse" boxes are for different functions; wipers, lights, starter, etc.

So the motor being grounded is what makes the circuit (I'm an electrician but car wiring and trailer wiring has always given me fits...lol).

Thank you so much for your expertese...

Yes, to your question.
If you're an electrician, the switch is a bit like a double pole-double throw type. The windows motor's direction is changed by running power through the motor in one direction or the other i.e. switching the 12V DC power and ground leads via a toggle

Yes, this can also be achieved (in electrical) by a momentary switch & relay.

Does the hatch door release switch also work without a relay?
