Pontiac Parisienne Ignition Switch Guide: 1971-1980
Everything you need to know about replacing the ignition switch on your classic Parisienne.
- The ignition switch is a separate electrical part from the mechanical key cylinder.
- Symptoms often involve the car not starting, stalling, or having flickering accessories.
- No recalls or TSBs are active for this part on a 1971-1980 Parisienne; failures are due to age.
- For a critical part, choosing a name brand like Standard Ignition over a generic 'Replacement' part is recommended for reliability.
Is Your Ignition Switch Failing?
On a classic car like the 1971-1980 Pontiac Parisienne, the ignition switch can fail from simple wear and tear over decades. The internal electrical contacts wear out, causing a range of problems. If you notice these signs, your ignition switch may be the culprit.
Common Failure Symptoms:
- Car Won't Start: You turn the key and nothing happens. The starter motor is silent, with no clicking or cranking, because the switch isn't sending power to it.
- Starts and Immediately Stalls: The engine may fire up only while the key is held in the 'start' position, but dies as soon as you release it to the 'run' position. This means the switch isn't maintaining power to the ignition system.
- Intermittent Electrical Problems: Your radio, dashboard lights, or power windows may cut out randomly while driving. Wiggling the key might make them flicker on and off, which points to worn contacts inside the switch.
- Stalling While Driving: This is a serious safety issue. A faulty switch can lose connection over a bump or during a turn, cutting all power to the engine and causing it to shut off without warning.
Ignition Switch vs. Ignition Lock Cylinder
It's easy to confuse these two parts. The Ignition Lock Cylinder is the mechanical part your key goes into. If your key is physically hard to turn, sticks, or won't go in, the lock cylinder is likely the problem. The Ignition Switch is the electrical component that the lock cylinder controls. If the key turns fine but you have electrical or starting issues, the switch is the more likely cause.
Choosing the Right Aftermarket Switch
For a vehicle of this age, finding a new original equipment (OEM) GM part is nearly impossible. The aftermarket is your primary source. The main choice is between a value-priced generic part and a recognized brand name.
| Brand Tier | Description | Typical Brands |
|---|---|---|
| Name Brand Aftermarket | These parts come from established companies known for consistent quality. For a critical component like an ignition switch, a brand like Standard Ignition is a reliable choice that is known to produce quality parts for American vehicles. | Standard Ignition |
| Value / Store Brand | Often labeled as 'Replacement' or a store's own brand, these are the most affordable options. While functional, their long-term durability and the quality of internal materials can be inconsistent compared to name brands. | Replacement |
Pro Tip: Consider Relays
If you have added high-power accessories like a modern stereo system or extra lighting, you may be putting too much load on the new ignition switch. A common practice in the hot rod community is to use relays to power high-draw circuits, which takes the strain off the ignition switch and helps it last much longer.
Frequently Asked Questions (FAQ)
Are there any recalls for the 1971-1980 Parisienne ignition switch?
No. While GM had major ignition switch recalls in the 2010s, they involved much newer vehicles from the 2000s. Searches of the National Highway Traffic Safety Administration (NHTSA) database show no recalls or specific technical service bulletins (TSBs) for the ignition switch on the 1971-1980 Pontiac Parisienne. Any failure today is due to normal age and wear.
Can I replace the ignition switch myself?
Yes, this is a DIY-feasible job for someone with basic mechanical skills. The switch is typically mounted on the steering column under the dashboard. Access usually involves removing lower dash panels. You will need to disconnect the battery first for safety. The job requires disconnecting electrical plugs and unbolting the old switch. No special programming is needed for this vehicle.
Why do my dash lights dim but the car won't crank?
This often points to a bad connection in the starting circuit. When you turn the key to 'start', the faulty ignition switch fails to send full power to the starter solenoid, but it does draw a large amount of current in the attempt. This current draw robs power from other systems, causing the lights to dim. A forum user described this exact symptom, which was traced back to the ignition system.
Should I replace the lock cylinder at the same time?
It's a good idea if you are already working on the steering column. The lock cylinder is also a wear item. If your key feels loose, sticky, or is hard to turn, you should replace the lock cylinder. If you only replace the switch, you will continue to use your old keys. A new lock cylinder will come with a new set of keys for the ignition only.
