Grounding problem with my power window motor on a 1997 chevy camero

What's with the 1994 C/K 2500 above an 2007 Silverado ? 07 on 94 frame ? New body have all the 07 electronics ?
Power Window System Controls (RPO A31/AN3/DL3)
The power window system will operate anytime the Retained Accessory Power (RAP) system is active or when the ignition switch is in the ACCY or ON position.
The driver master control switches are integrated into the DDS. When a power window switch is activated in the up or down positions the DDS 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 DDS 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 DDS continues to monitor the motor current to verify proper window motor operation.
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)
Do you know what GMLAN is ? serial data communication network

Passenger Power Window Inoperative

1. Ignition OFF, disconnect the C1 harness connector at the PDS.
2. Test for less than 1 ohm between the ground circuit terminal 6 and ground.
?‡'
If greater than the specified range, test the ground circuit for an open/high resistance.

3. Ignition ON, verify that a test lamp illuminates between the B+ circuit terminal 2 and ground.
?‡'
If the test lamp does not illuminate, test the B+ circuit for a short to ground or an open/high resistance.

4. Ignition OFF, reconnect the harness connector at the PDS.
5. Ignition ON, observe the scan tool Passenger Window Switch parameters while using the passenger power window switch. The reading should change between Off/Up/Down/Express Down.
?‡'
If the parameter does not change, replace the PDS.

6. Ignition OFF, disconnect the harness connector at the passenger window motor.
7. Connect a test lamp between control circuit terminal A and control circuit terminal B.
8. Ignition ON, command the passenger window UP and DOWN by using the passenger window switch. The test lamp should illuminate when commanding the UP and DOWN states.
?‡'
If the test lamp is always OFF during either of the commands, test for a short to ground or open/high resistance on either control circuit. If the circuits test normal, replace the PDS.



?‡'
If the test lamp is always ON, test for a short to voltage on either control circuit. If the circuits test normal, replace the DDS.


9. If all circuits test normal, test or replace the passenger window motor.

You would need to test the switch with a meter to see if it has power and ground in both up and down positions.
Since the driver's window is used the most, often times the problem is the motor.

pull the plug from the back of the window motor so you can put power and ground to the two terminals just for a sec and reverse the wires and do it again, that should move the window up and down if it will not you need a motor. if it moves then you need power

remove the power window switch and run a jumper wire to the TAN wire ground to the BLACK wire then if the switch is working roll the window up if the problem is the switch then jump power to the light/blue wire and ground to the white wire to roll up the driverside window , switch them to roll window down, power to brown/white and ground to violit and the passangerside window will roll up, switch them to roll it down.

ground problem mine has this problem also has no ground in up position will go down fine . I have jump ground in up position.

it could be a bad driver door master switch or bad window motors, the best way to pin point the problem is to remove the door panel off every door that doesnt work and then test for power and ground while hitting the switch, if it has power and ground then motor is no good,start there, another option is to test for power and ground at the switches,

Could be the motor. I would try seeing if the ground came loose. Same thing happened to my passeneger window. I reconnected the ground and it works like it never quit. Try the wiring under the passenger and driver seat. The ground for the passenger window in my car was under the passenger seat.

Reverse your test light connector, connect it to power so you can check for ground at window motor, flip switch up or down should have ground at both wire's while flipping switch to up or down, more then likely your not going to have ground at the up position, do same test at harness before passenger door switch if no ground master switch bad.

On the passenger door, look for a broken wire in the door opening.

So you found power on one of the two wires. That was with holding the switch in one position, either up or down, right? Try it again, now hold the switch in the opposite position as before, now the other wire that had no power the first time should now have power. If not, probably a break in the wiring, look in the door jamb. If not a broken wire in the passenger door, it could be in the driver's door.

You see, the power is reversible to the window motors. When power goes down one wire to the motor, the other wire serves as a ground. The ground path goes back to the driver's master switch, where the ground for all the windows originate. Ground wire from master switch carries power to ground somewhere inside the cabin. Since other windows work, your ground is good. but the pass. window is, or seems to be missing a wire. Check by looking for power on both wires, but the window switch has to be opposite from the first time for the second wire to have power. Only if both show power is the wiring good, but they wont both show power at the same time-the switch has to be in right position to show power.
I hope this is clear, post back if you don't understand.

Oh yes, use the ohmmeter function of your multi-meter to check the wires' integrity. Just don't have any power on any of the wires you are checking, but check between the pass. door and the driver's master. Check both wires that go to the passenger window. That should tell you if you have a break in the wiring.

May be a bad motor. Check for power and ground. One wire will have power and the other will be grounded, when you press the window switch down it will be reversed, It grounds through the drivers switch.
