1987 Pontiac Tempest Ignition Switch Guide
Solve starting problems and electrical issues by understanding how to choose the right new ignition switch for your Tempest.
- Symptoms often appear as electrical problems, like a no-start condition, stalling, or flickering dash lights.
- This part is not the same as the ignition lock cylinder where you insert your key; it is the electronic switch behind it.
- There are no recalls for this specific part; do not confuse it with the major GM recall for newer cars.
- Aftermarket brands like Standard Ignition are reliable choices, as new OEM parts are no longer available.
Is Your Ignition Switch Failing?
When the ignition switch in your 1987 Pontiac Tempest starts to wear out, it can cause confusing electrical problems that might seem unrelated. Because this part controls power to so many systems, a bad connection inside the switch can leave you stranded or cause systems to fail while you're driving. Recognizing the signs early can save you a lot of trouble.
Common Symptoms of a Bad Ignition Switch:
- Car Won't Start or Crank: You turn the key and nothing happens. The dashboard lights may or may not come on, but the engine doesn't even try to turn over. This silence points to the switch not sending power to the starter.
- Starts and Immediately Stalls: The engine fires up when you're holding the key in the 'Start' position, but dies as soon as you let the key return to the 'On' position. This means the switch isn't maintaining power to the ignition system.
- Flickering Dashboard Lights: You might notice the dash lights, gauges, or radio flicker or cut out randomly while driving, especially when hitting a bump. This indicates a loose internal connection in the switch.
- Accessories Don't Work: The radio, wipers, or heater fans might not work in the 'Accessory' or 'On' position, even though the car starts.
- Stalling While Driving: This is a serious safety issue. A faulty switch can lose contact and cut power to the engine while you are on the road, which also causes a loss of power steering.
Ignition Switch vs. Lock Cylinder
It's easy to confuse the ignition switch with the ignition lock cylinder. The lock cylinder is the mechanical tumbler you put your key into. If your key is hard to turn or gets stuck, the lock cylinder is the likely problem. The ignition switch is the electronic component that the lock cylinder operates. If you have electrical problems like a no-start or stalling, the switch is the more probable cause.
Choosing the Right Aftermarket Ignition Switch
For the 1987 Pontiac Tempest, the original OEM ignition switches are no longer produced by GM. The aftermarket is your only source for new parts. Fortunately, the available brands offer reliable quality.
Brand Tiers
- Standard Ignition (Standard Motor Products): Often considered a top-tier aftermarket brand, Standard Ignition produces parts that are designed to meet or exceed original specifications. They are known for using quality materials, like copper alloy conductors, and for rigorous testing. For an owner looking for the best-available, longest-lasting part, Standard Ignition is a trusted choice.
- Replacement: This category typically refers to house brands or other value-oriented manufacturers. These switches are designed to be a direct fit and function correctly at a lower price point. While they are a cost-effective solution to get your Tempest back on the road, they may not have the same long-term durability or undergo the same level of testing as premium brands like Standard.
A Note on the 1987 Pontiac Tempest: This vehicle was sold in Canada and is a direct twin of the Chevrolet Corsica. Parts are identical between the two models. When searching for information or parts, expanding your search to include the "1987 Chevrolet Corsica" will provide many more results.
Cost of Replacing the Ignition Switch
The cost to replace the ignition switch is reasonable, as the parts are not expensive and the labor is straightforward for a professional mechanic.
| Part Type | Estimated Cost |
|---|---|
| New Aftermarket Ignition Switch | $41 - $42 |
| Shop Labor | $100 - $180 |
| Total Estimated Cost | $141 - $222 |
Frequently Asked Questions
Are there any recalls for the 1987 Tempest ignition switch?
No. There are no recalls from the NHTSA for the ignition switch on the 1987 Pontiac Tempest or its twin, the Chevrolet Corsica. The widely publicized GM ignition switch recall of the 2010s affected much newer vehicles and does not apply to your car.
Can I replace the ignition switch myself?
Yes, this is a job that a DIYer with some experience can handle. It involves removing the plastic trim panels under the dashboard and around the steering column to access the switch. You will need basic hand tools. Always disconnect the battery's negative terminal before beginning any electrical work.
My 'SECURITY' light is on. Is that the ignition switch?
Probably not. The 'SECURITY' light on the dashboard is related to the GM Vehicle Anti-Theft System (VATS). This system uses a key with a small black resistor pellet. The ignition lock cylinder (where the key goes) reads this pellet. If the light is on and the car won't start, the issue is likely with the lock cylinder's contacts or the wiring, not the ignition switch itself.
How do I know if the switch is bad, and not the battery or starter?
A bad battery usually causes slow cranking or a rapid clicking sound. A bad starter often makes a single, loud click. A bad ignition switch, however, typically results in complete silence when you turn the key to 'start'. If you can wiggle the key in the ignition while the engine is running and it causes the engine to sputter or the dash lights to flicker, the ignition switch is almost certainly failing.
