Is Your Wiper Switch Failing?
When the wiper switch in your Buick Century starts to go bad, the symptoms can be confusing. The problem might seem random at first. Before assuming the wiper motor or wiring is the issue, check if the switch itself is showing these common signs of failure. A faulty switch is a frequent cause of wiper system problems.
| Symptom | Description |
|---|---|
| Wipers Don't Turn On | You move the switch lever, but nothing happens at all. This can be intermittent or a complete failure. While this could also be a bad motor, the switch is a common starting point for diagnosis. |
| Wipers Stuck on One Speed | Often, the wipers will only work on the highest speed setting. This happens when the internal contacts for the low and delay speeds have worn out, but the high-speed contact still works. A complaint was filed with the NHTSA for a 1991 Century where the wipers failed specifically on the high setting. |
| Wipers Won't Turn Off | You may find that the wipers continue to run even when you put the switch in the 'Off' position. This points to a short or failed contact inside the switch assembly. |
| Intermittent or Random Operation | The wipers may turn on by themselves, stop in the middle of the windshield, or only work when you jiggle the lever. This erratic behavior is a classic sign of worn internal switch components. |
Choosing the Right Aftermarket Wiper Switch
For a vehicle like the 1986-1991 Buick Century, finding a new original equipment (OEM) wiper switch from GM is highly unlikely. The primary options are new aftermarket parts or a used part from a salvage yard. Given the amount of labor involved in replacement, a new aftermarket part with a warranty is the most reliable choice.
Brand Options: Standard vs. Premium
Your main choices for a new switch will be from established aftermarket manufacturers.
- Standard Ignition (SMP): Standard is a well-known brand in the aftermarket and has been around for a long time. Forum users and mechanics often consider their parts to be a dependable, quality replacement that fits and functions like the original. For a critical part like a multi-function switch, SMP is generally regarded as a safe and reliable option.
- Rostra Powertrain: Rostra is widely recognized for its aftermarket cruise control systems, which often include multi-function switches. While they have a solid reputation in that category, there is less specific owner feedback available for their standalone wiper switches compared to Standard. However, they are an established brand that produces a wide range of vehicle electronics.
Pro Tip: Before ordering, confirm if your car has intermittent (delay) wipers. The switches are different for cars with and without this feature. The correct switch must be installed for all functions to work properly.
Wiper Switch Replacement Cost
The cost to replace the wiper switch involves the part itself and labor. Replacing the switch is an advanced job because it is located inside the steering column and requires special tools.
| Part or Service | Estimated Cost |
|---|---|
| New Aftermarket Wiper Switch | $105 - $143 |
| Shop Labor for Installation | $175 - $300 |
| Total Estimated Cost | $280 - $443 |
Cost estimates are for parts and labor only and do not include taxes or shop fees. Labor is estimated at 1.5-2.5 hours.
Frequently Asked Questions (FAQ)
Can I replace the Buick Century wiper switch myself?
This is considered an advanced DIY repair. It requires removing the plastic shrouds around the steering column, and may require removing the steering wheel and a lock plate. This process requires special tools like a steering wheel puller and a lock plate compressor tool. While some have managed the repair without pulling the wheel, it is a tight space to work in. If you are not comfortable with this level of disassembly, it is best to have a professional mechanic do the job.
Were there any recalls for the 1986-1991 Buick Century wiper switch?
No, searches of the National Highway Traffic Safety Administration (NHTSA) database show no specific recalls for the windshield wiper switch on the 1986-1991 Buick Century.
Could my problem be the wiper motor instead of the switch?
Yes, a bad wiper motor can cause similar symptoms, such as slow operation or not working at all. However, if the wipers only work on one speed or operate randomly, it is more likely to be the switch. A mechanic can perform an electrical diagnosis to confirm which part has failed before you buy parts.
Why won't my wipers 'park' in the correct position?
The 'park' function, which returns the wipers to the bottom of the windshield when turned off, is controlled by both the switch and a special circuit in the wiper motor. If the wipers stop in the middle of the glass, it can be caused by a bad switch, but it can also indicate a problem with the motor's internal park switch.
