A Deep Dive into the 1986-1996 Buick Regal Wiper Switch
Everything a Regal owner needs to know about diagnosing and replacing a faulty wiper switch.
- Wiper switch failure symptoms (like not turning off) can overlap with wiper motor problems; diagnosis is important before buying parts.
- New OEM switches are generally not available; aftermarket brands like Standard Ignition and Rostra are reliable, quality alternatives.
- Replacement is a manageable DIY task for most home mechanics, requiring only basic hand tools and about 1-2 hours.
- There are no specific recalls or TSBs from NHTSA for the wiper switch on this generation of Buick Regal.
Is Your Wiper Switch Failing?
When your wipers act up, it's easy to blame the motor, but the switch is a common point of failure. Because it's a mechanical part with electrical contacts, it wears out over time. Look for these classic signs of a failing wiper switch in your Regal.
Common Failure Symptoms:
- Wipers Won't Turn On: You move the switch, but nothing happens. This is the most obvious sign of a completely failed switch or a blown fuse.
- Wipers Won't Turn Off: You turn the switch to the 'off' position, but the wipers keep going. This often points to a problem inside the switch or a faulty park circuit in the wiper motor.
- Intermittent Operation: The wipers work sometimes but not others. You might have to jiggle the switch to get them to work, indicating worn internal contacts.
- Only One Speed Works: You might lose the high-speed or low-speed setting. This suggests a specific contact inside the switch has failed.
- Delay Wipers Don't Work: If your Regal has intermittent wipers, a failure of this function often lies within the switch assembly.
Switch or Motor?
Many symptoms of a bad wiper switch can also be caused by a failing wiper motor. A common issue on these GM vehicles is a problem with the 'park' function inside the motor, which tells the wipers to stop at the bottom of the windshield. If your wipers won't turn off or stop in the middle of the glass, the motor's park circuit is a likely culprit. Diagnosis is key before buying parts.
Choosing a New Aftermarket Wiper Switch
For a vehicle like the 1986-1996 Regal, finding a new OEM (Original Equipment Manufacturer) wiper switch from GM is highly unlikely as the parts are long discontinued. The best option for a new part is the aftermarket. Fortunately, reputable companies produce reliable replacements.
Here are the brands available in our inventory:
- Standard Ignition (Standard Motor Products): A well-known and respected aftermarket brand founded in 1919. They often manufacture parts for major auto parts store brands and are known for quality. Their switches often feature copper alloy conductors for better conductivity.
- Rostra Powertrain: A large manufacturer of both OE and aftermarket electronic parts. They hold key quality certifications (ISO-9001 and IATF-16949), indicating a commitment to reliable manufacturing processes.
Pro Tip: Both Standard Ignition and Rostra are solid choices for this repair. There is no significant quality difference for this specific part that would justify choosing one over the other. Your decision can confidently be based on price and availability.

Frequently Asked Questions
Can I replace the wiper switch myself?
Yes, this is a DIY-friendly job for someone with basic tools and patience. The process involves removing the plastic covers around the steering column to access the switch. You will need to carefully unplug the old switch and snake the new wiring harness down the column. The main challenge is working in a tight space.
Why do my wipers stop in the up position?
This is almost always a problem with the wiper motor's internal park circuit, not the switch itself. The park circuit is responsible for cutting power only after the wipers have returned to their resting position at the bottom of the windshield. When it fails, they stop the moment you turn the switch off.
Are there any recalls on the 1986-1996 Regal wiper switch?
No. Searches of the National Highway Traffic Safety Administration (NHTSA) database show no open recalls for the windshield wiper switch on the 1986-1996 Buick Regal.
Do I need any special tools for the replacement?
For just the wiper switch, you typically only need basic hand tools like a screwdriver set and possibly a socket set. The switch itself is usually held on with a couple of screws. You do not need a steering wheel puller for this specific job, as the switch is mounted externally on the column.
