Is Your Buick Regal Window Motor Failing?
Power window failures are a common issue on many GM vehicles from this era, including the 1988-1997 Buick Regal. The problem can be the motor, the switch, or the window regulator that holds the glass. Often, the first sign is a window that moves slower than it used to. Eventually, it may stop working altogether.
Common Symptoms of a Bad Window Motor
🎬 Watch this video to identify signs of a failing motor.- Slow or Sluggish Operation: The window moves up and down much slower than normal. This is often the first sign of a wearing motor.
- Intermittent Function: The window works sometimes but not others. Hitting the door panel or slamming the door might temporarily make it work, which points to a failing motor.
- Clicking or Whirring Sound, But No Movement: If you press the switch and hear a sound from the door, power is reaching the motor, but it's unable to move the window. This could mean the motor has failed internally or the regulator is broken.
- Window Stops Mid-Travel: The window goes up or down part-way and then stops, requiring multiple presses of the switch to move.
- Complete Failure: The window doesn't respond at all, and you hear no sound. While this can be a dead motor, it's important to first check the fuse and the window switch.
Don't Replace the Wrong Part
Before buying a new motor, it's crucial to diagnose the problem. A bad window switch or a blown fuse can mimic the symptoms of a failed motor. A definitive test is to remove the door panel and apply 12V power directly to the motor's connector. If the motor runs, the problem is elsewhere in the system (switch, wiring). If it doesn't, the motor is confirmed to be bad.
Choosing a New Aftermarket Window Motor
For a vehicle of this age, aftermarket parts offer a significant cost saving over OEM parts, which may be difficult to find new. Aftermarket brands have a long history of producing these common GM motors. Many owners report success with aftermarket options.
Aftermarket Brand Tiers
- Dorman: A widely available brand offering a vast selection of parts, often with a lifetime warranty. They are a common choice for DIY repairs and are known for matching OE fit and function. 🎬 See how Dorman regulators compare to original equipment parts.
- Cardone: Another major player in the aftermarket, Cardone offers both new and remanufactured window motors. They are a popular choice and are often considered a reliable replacement.
- Replacement / Skyward / Value-Priced Options: These brands provide a budget-friendly solution. While they may not have the same brand recognition as Dorman or Cardone, they can be a good choice for owners looking for the most economical repair. Quality can be inconsistent with cheaper brands, so checking warranties is a good idea.
Pro Tip: Motor Only vs. Motor & Regulator Assembly
On these Regals, the motor is often riveted to the regulator from the factory. While you can buy just the motor, it requires drilling out the old rivets and bolting the new motor on. For a simpler, though more expensive, repair, you can buy a complete motor and regulator assembly. This replaces the entire mechanism and is often easier for a DIY repair.

Frequently Asked Questions
Do I need a special tool to replace the window motor?
If you are replacing only the motor, you will need a drill to remove the factory rivets holding the old motor to the regulator. The new motor typically bolts on. Basic hand tools like a socket set and screwdrivers are needed to remove the door panel. Some forum users suggest using a hole saw to access the motor bolts without removing the entire regulator assembly.
Are all window motors for the 1988-1997 Regal the same?
The motors themselves are often interchangeable between front/rear and left/right on many GM cars of this era. However, the regulator assembly is specific to the door's location (e.g., front driver's side). Always confirm the fitment for your exact year and door location before purchasing.
My window is stuck down. How can I get it up before I can fix it?
If the motor has failed, you can often remove the door panel, unplug the motor, and manually push the glass up. You can then use a wedge or strong tape to hold it in place until you can perform the repair. This is a temporary solution to secure your vehicle.
Are there any recalls on the window motors for this Buick Regal?
A search of the National Highway Traffic Safety Administration (NHTSA) database did not show any specific recalls for the window motors on the 1988-1997 Buick Regal. Failures are generally due to age and wear rather than a manufacturing defect that prompted a recall.
