Where the relays for the power windows and sunroof?

Here is your answer from Just Answer. Exactly the same issue and caused by the 'RAP Relay' (Retained Accessory Power).

https://www.justanswer.com/pontiac/atv7z-power-windows-sunroof-stop-working-25a-fuse-back.html

It is located in the Passenger Side Fuse Box.

....

check the fuses /relays then power feed to door and into switch cluster---sunroof off different feed ---damage wiring possible in harness feed between door hinge area --at cluster or failed door panel cluster but will need a multi-meter or at least a test light

Not a fuse problem .
Voltage is applied to the left front window switch through the PWR WINDOWS PWR SUNROOF circuit breaker and to circuit 143
Retained Accessory Power (RAP) Circuit Description
The Body Control Module (BCM) controls the Retained Accessory Power (RAP) feature. The RAP feature allows for the operation of the following components for 10 minutes (or until a vehicle door opens) after the ignition switch turns from the RUN or ACC to the LOCK position:
• The radio
• The power windows
• The power sunroof (if equipped)
The BCM interfaces with the vehicle's power distribution through the RAP relay. The RAP relay allows the BCM to control the application of power to circuit 75. Circuit 75 provides power to the following circuits:
• Circuit 43 -- Radio
• Circuit 143 -- Power windows, and the power sunroof, if equipped
When the ignition switch is in either of the following positions, the BCM energizes the RAP relay by grounding circuit 707:
• ACC
• RUN
The BCM turns OFF the RAP relay when the ignition switch is in the START position. This action disables the RAP feature during the engine crank and bulb test.
When the ignition switch turns from the RUN or ACC position to the LOCK position with all of the vehicle doors closed, the BCM leaves the RAP relay energized for 10 minutes, or until any vehicle door opens. (The BCM detects a ground signal in circuit 49 or circuit 727).
The BCM resets the RAP timer when the ignition switch turns from the LOCK or OFF position to the ACC or RUN position.


I would check the RAP relay . Accessory Time Delay (RAP) Relay
Behind the IP compartment, attached to the underside of cross-car beam.

Is the motor receiving power? If not you have to check electrical system to locate the place that is not transmitting power. Could be a fuse/relay, switch, bad connection.

If the motor is turning and nothing happens then the drive mechanism from motor to sunroof is stripped. Not good.

Power is supplied to the Power windows and sunroof through the power window circuit breaker. That circuit breaker is supplied power through the RAP (retained accessory power) Relay, the RAP relay also supplies power to the radio. The RAP relay is also fuse protected by the RAP fuse in the under hood fuse block. The RAP relay is energized by the BCM body control module.

The RAP relay is responsible for the radio and windows working after the igntion is turned off.

The first place to check would be the RAP fuse in the under hood fuse block and then the RAP relay in the Body fuse block.

A list of the BODY relay block located on the left side of the dash to the right of the interior fuse block is below:

hey did you ever figure this out? Im working on the same problem right now... have power to the sunroof and just replaced the 25amp circuit breaker that is right after the sunroof... I have a circuit diagram if it would help you at all

Don't know Saturns well, but could be a "fusible link" blown. These are in side power wires usually near battery or starter motor.

try your relay

you have a bad power window relay the relay should be in the engine compartment your owner's manual should refer to it it controls both the window and, sunroof circuits replace this relay
