1. Identify the Problem:
* Window won't go up or down at all: This suggests a problem with the motor, regulator, switch, or wiring.
* Window goes down but not up (or vice versa): This often points to a problem with the regulator, motor, or possibly a faulty switch.
* Window moves slowly or intermittently: This could indicate a worn regulator, weak motor, or dirty/damaged tracks.
* Window makes unusual noises (grinding, clicking): This usually points to a problem with the regulator, tracks, or motor.
* Switch doesn't work: This is the simplest problem, potentially just a bad switch.
2. Troubleshooting Steps:
* Check the Fuse: Locate your car's fuse box (usually under the hood or dashboard) and check the fuse for the power windows. Replace it if blown.
* Test the Switch: Try the other window switches. If they work, the problem is likely with the specific switch, the motor for that window or its wiring. If none of the switches work, the problem is more likely in the master switch, wiring, or power source.
* Check the Wiring: Inspect the wiring harness connected to the window motor and regulator. Look for any broken, frayed, or disconnected wires. This often involves removing the door panel.
* Listen for the Motor: When you press the switch, can you hear the motor trying to work? If not, the motor is likely dead or there's a power problem before the motor. If you hear a clicking, it could be a bad motor or a problem with the regulator.
* Test the Regulator: If you hear the motor working but the window won't move, the regulator is the likely culprit. This requires removing the door panel.
3. Repair Steps (Will require removing the door panel):
* Removing the Door Panel: Consult a repair manual (Haynes or Chilton) specific to your 1998 Oldsmobile Intrigue. Removing the door panel involves carefully prying off clips and removing screws. Be gentle to avoid breaking clips.
* Accessing the Motor and Regulator: Once the door panel is off, you'll have access to the window motor and regulator.
* Replacing the Switch: If the switch is faulty, replacing it is relatively straightforward, and often involves unplugging the old one and plugging in the new one.
* Replacing the Motor: Replacing the motor requires disconnecting the wiring harness and removing the old motor. Ensure you get a replacement motor that's correct for your model.
* Replacing the Regulator: Replacing the regulator is the most involved repair. It often involves removing the window glass carefully (take pictures or make notes of its position) and then unbolting the regulator from the door. Installing the new regulator usually involves reversing the removal steps.
* Lubricating the Tracks: If the window moves slowly or sticks, lubricate the window tracks with silicone-based lubricant.
4. Tools Required:
* Screwdrivers (Phillips and flathead)
* Panel removal tools (plastic pry tools)
* Wire strippers/crimpers (if replacing wiring)
* Socket wrench (potentially)
* Replacement parts (switch, motor, regulator, fuses)
* Repair manual (highly recommended)
* Silicone-based lubricant
Important Considerations:
* Repair Manual: A repair manual for your specific vehicle is essential. It will provide detailed instructions and diagrams for removing the door panel and accessing the window components.
* Safety: Disconnect the battery negative terminal before working on the electrical system.
* Professional Help: If you're not comfortable working on car repairs, it's best to take your car to a qualified mechanic. Replacing the regulator, in particular, can be challenging.
