Drivers window won't go down

Use a test light and check if getting power on that hot wire at the connection to motor. Check it back to the fuse panel by holding the down button if window up and vice-versa. Since motor was replaced, You know it's good but no power to it. It's got to be a broken wire or unplugged somewhere. Find that spot with a test light. ALL you can do is test it till you find that broken spot.

Have to get access to the switch in the door panel
& door some voltage tests

Going to be difficult without a wiring diagram to
actually find a problem

If the switch & motor works, remove the door panel &
replace a broken window regulator

Sounds like your drivers side window regulator motor gear is bad as far as the other windows drivers door switch is most likely bad if you dont have experience working on electrical or have never taken apart a door panel I would recommend seeing a mechanic. To check the switch you have to disassemble passenger door panel accesa the window regulator motor disconnect the weatherpack connect hook up multimeter and test for power while having an assistant push the window switch down

How about when the radio is on & the key is off or
in your hand,if you open either front door does the radio go off
& do you lose the delayed window feature assuming you have that
If so you problem is a delayed accy relay
Next would be the front door switches
I will give you credit for what you tried
but fail to see why you would switch motor
from door to door,they work powered directly or they don't
I would think your battery would have gone dead by now
if the relay failed to time out or go to sleep

I would be guessing,(we do that a lot)
that the driver door sw is a master & thus
neither works

When you do voltage drops-- have the alternator
running, so you have a more stable voltage

Neither master switch on driver's door, nor the passenger switch works? You will have to take off inner panel on pass. door to get to the window motor, and check wiring or motor malfunction.

Are you aware of the fact that there are door modules ? Controlled electronically !
Power Window Inoperative - Driver Door
2
Operate the driver power window in the UP and DOWN directions.
Does the driver power window operate properly?
YES - Go to Testing for Intermittent Conditions and Poor Connections in Wiring Systems
NO - Go to Step 3
3
Install a scan tool.
Monitor the Driver Window Status Data parameter in the driver door inputs list.
Does the Driver Window Status Data parameter display an active state?
YES - Go to Step 11
NO - Go to Step 4
4
Monitor the Driver Window Status Data parameter in the driver door module (DDM) inputs list.
Activate the driver power window switch in the up and down positions.
Does the Driver Window Status Data parameter change accordingly?
YES - Go to Step 5
NO - Go to Step 11
5
Connect a test lamp to a good ground.
Backprobe the battery positive voltage circuit at connector C1 cavity D.
Does the test lamp illuminate?
YES - Go to Step 6
NO - Go to Step 13
6
Disconnect the driver power window motor.
Connect a test lamp to a good ground.
Probe the power window motor up control circuit at the power window motor harness connector.
Activate the power window switch to the UP position.
Does the test illuminate?
YES - Go to Step 7
NO - Go to Step 9
7
With the test lamp still connected to a good ground, probe the power window motor down control circuit.
Activate the power window switch to the DOWN position.
Does the test lamp illuminate?
YES - Go to Step 8
NO - Go to Step 10

You probably have a bad door module .

Most likely the window motor/regulator assembly has gone bad.Check for good fuse, if good pull out the switch and make sure you have power to it, if you do then remove door panel and test for power at motor, if u have power but motor won't work replace. Suggest replacing the regulator assembly as well because the cables often fray and cause problems as well.

Fore remove the door panel in a SL2, you have to take off the door handle. You have to disengage the door locking mechanism from the door handle, then unscrew the panel and take it off.

The door handle unhinges from the locks and from the window controls. If your windows are electric, just unsnap the cord attached and leave it hanging out.

You may have to work with the door handle as it won't come out of the slot very easily and you don't have a lot of room. A flat bladed screwdriver with a long metal piece should work to unsnap it.

Diagnosis & Testing
Driver's Window Switch

1. Turn the ignition OFF, disconnect the harness connector at the driver window switch.
2. Test for infinite resistance between the signal terminals A and B and the B+ circuit terminal E with the passenger window switch in the INACTIVE position. If less than infinite resistance, replace the driver window switch.
3. Test for less than 2 ohms of resistance between the signal terminal A and the B+ circuit terminal E with the passenger window switch in the UP position. If greater than 2 ohms, replace the driver window switch.
4. Test for less than 2 ohms of resistance between the signal terminal B and the B+ circuit terminal E with the passenger window switch in the DOWN position. If greater than 2 ohms, replace the driver window switch.
5. Test for infinite resistance between the signal terminals F and H and the B+ circuit terminal E with the driver window switch in the INACTIVE position. If less than infinite resistance, replace the driver window switch.
6. Test for less than 2 ohms of resistance between the signal terminal F and the B+ circuit terminal E with the driver window switch in the UP position. If greater than 2 ohms, replace the driver window switch
7. Test for less than 2 ohms of resistance between the signal terminal H and the B+ circuit terminal E with the driver window switch in the DOWN position. If greater than 2 ohms, replace the driver window switch.

Passenger's Window Switch

1. Turn the ignition OFF, disconnect the harness connector at the passenger window switch. Test for infinite resistance between the signal terminals G and F and the B+ circuit terminal with the switch in the INACTIVE position. If less than infinite resistance, replace the switch.
2. Test for less than 2 ohms of resistance between the signal terminal G and the B+ circuit terminal with the switch in the UP position. If greater than 2 ohms, replace the switch.
3. Test for less than 2 ohms of resistance between the signal terminal F and the B+ circuit terminal with the switch in the DOWN position. If greater than 2 ohms, replace the switch.

Window Motor

1. Install a 30-amp fused jumper wire between the control terminal A and 12 volts. Momentarily install a jumper wire between the control terminal B and ground. The motor should perform the UP or DOWN function.
2. If the function does not perform as specified, replace the motor.
3. Reverse the jumper wires; the motor should perform the DOWN or UP function.
4. If the function does not perform as specified, replace the motor.

Removal & Installation
Window Motor & Regulator

1. Raise the window to the full UP position.
2. Remove the upper trim panel.

I hope helped with this; good luck.

Does the rear window work from the passenger switch?
