1985-1993 Saab 9000 Side Window Glass: Body Styles, Regulators, and Replacement

Symptoms of a Failing Window System

When a side window on a Saab 9000 stops working correctly, the glass itself is rarely the problem unless it's physically broken. The issue is almost always with the electrical or mechanical parts that move the glass. Understanding these symptoms can help you diagnose the problem accurately.

Window is Slow, Stuck, or Crooked

If the window moves much slower than it used to, hesitates, or tilts to one side as it moves, this often points to a problem with the window regulator. The regulator, a mechanism of arms or cables, may be bent, binding, or the motor may be weakening. Sometimes, the plastic rollers that guide the glass 🎬 Watch: How to replace broken window regulator rollers in its track break, causing the window to become misaligned or stuck.

Grinding, Clicking, or Popping Noises

Loud noises from inside the door when you press the window switch are a clear sign of a mechanical failure. A grinding or clicking sound often means the regulator's gears are stripped or a cable is frayed and bunching up. A loud pop or bang, followed by the window no longer working, can indicate a snapped regulator cable or that the glass has separated from its mounts.

Window Drops Into the Door

If the window suddenly falls into the door cavity, the window regulator has likely failed completely. This is a common failure mode where a cable snaps or the lift plate that holds the glass breaks. The motor might still make a whirring sound, but the glass is no longer attached to the mechanism.

Window Switch is Unresponsive

If nothing happens when you press the switch, and you don't hear a motor sound, the problem could be electrical. It could be as simple as a blown fuse, a faulty window switch, or a bad motor. On these older cars, the wiring that passes between the door and the car body can also become brittle and break from repeated opening and closing of the door.

Buying a Used 1985-1993 Saab 9000 Side Window Glass

Since new OEM glass for these vehicles is becoming scarce, a used original part is often the best option. Here’s what to check before you buy:

• Verify Body Style: As mentioned, for rear doors, you must match the glass from a 4-door sedan to another sedan, or a 5-door hatchback to another hatchback.
• Inspect for Scratches: Hold the glass up to the light and check for deep scratches or heavy pitting from years of use. Minor surface marks are normal, but deep gouges can be distracting and weaken the glass.
• Check the Sash Channel: The metal channel bonded to the bottom of the glass is crucial. Ensure it is not bent, heavily rusted, or separated from the glass. The plastic clips or mounting points for the regulator should also be intact. A damaged sash channel will make installation impossible.
• Confirm Tint: All original Saab 9000 glass from this era should have a slight green tint. Compare it to your existing windows to ensure a good match.
• Why Used OEM is a Good Choice: For a part like tempered side glass, a used OEM piece is often superior to a new aftermarket one. The fit, curvature, and tint color are guaranteed to match factory specifications, ensuring a proper seal and original appearance.

Known Issues, TSBs, and Recalls

The power window system, particularly the regulator, is the most common source of problems. The regulators use cables and plastic components that can wear out and break over time. There are no widespread recalls or Technical Service Bulletins (TSBs) specifically for the side window glass itself on the 1985-1993 Saab 9000. Most issues are related to the mechanical regulators and motors, which are considered normal wear-and-tear items on a vehicle of this age.

Replacement Overview and Difficulty

Replacing the side window glass is a moderately difficult task for a DIY mechanic.

Difficulty: 3 out of 5

The general process involves:

1. Removing the interior door panel, which includes detaching the door handle, armrest, and any switch panels.
2. Carefully peeling back the plastic vapor barrier to access the inside of the door.
3. Removing the old glass. If the glass is intact, you'll lower it until you can access the bolts that hold it to the window regulator. If it's shattered, you will need to thoroughly vacuum all the glass fragments from inside the door.
4. Maneuvering the new glass into the door and down into the window channel.
5. Bolting the new glass to the regulator lift plate and testing its movement.
6. Reassembling the door.
