Is Your P10's Ignition Switch Failing?
The ignition switch in a classic Chevrolet P10 is a mechanical part that wears out over time. After decades of use, the internal contacts can get worn or corroded, leading to a variety of electrical problems. If you're experiencing intermittent starting issues, or if your truck stalls unexpectedly, the ignition switch is a likely suspect. Wiggling the key in the ignition to get the dashboard lights to come on is a classic sign of a worn-out switch.
Common Failure Symptoms
- No-Crank, No-Start: You turn the key and nothing happens, or you only hear a single click.
- Engine Stalls While Driving: The switch can lose connection internally, cutting power to the ignition system and shutting the engine off, sometimes when hitting a bump.
- Accessories Don't Work: The 'Accessory' key position fails to power the radio, heater fan, or other systems.
- Key is Hard to Turn: The mechanical part of the switch or the lock cylinder it connects to may be binding or worn out.
- Dashboard Lights Flicker: Jiggling the key causes the lights on your instrument cluster to flash on and off. 🎬 Watch a detailed breakdown of common bad ignition switch symptoms.
Choosing the Right Aftermarket Ignition Switch
For a vintage vehicle like the 1963-1967 P10 Series, finding new Original Equipment Manufacturer (OEM) parts is nearly impossible. The good news is that the aftermarket provides quality replacements that meet or exceed the original specifications. The ignition switch used in these trucks was common across many GM vehicles of the era, so parts are readily available.
Brand Tiers: What to Expect
When shopping for a new switch, you'll likely encounter these brands:
- Standard Ignition (Standard Motor Products): Often considered a top-tier aftermarket brand, Standard produces parts that are well-regarded for their quality and fit. They manufacture a wide range of ignition components and have a long-standing reputation in the repair industry. Reviews often point to good performance and reliability, though occasional manufacturing defects like poor threads have been noted.
- Rostra Powertrain: Rostra is another established manufacturer, known for producing a variety of electronic components for both OEM and aftermarket applications. While they are a large supplier for transmission parts, their general reputation for quality is solid.
Both brands offer a reliable solution for your P10. Given the simplicity of the part, either choice will likely restore proper function to your ignition system. The most important factor is ensuring the part number is correct for your specific year.

Pro Tip: Check the Connector!
After decades of use, the plastic electrical connector that plugs into the back of the ignition switch can become brittle and the terminals can corrode. While you're replacing the switch, inspect the connector and wiring for any signs of melting, cracking, or corrosion. It's often a good idea to purchase a new connector pigtail at the same time, as the old one may break during removal.
Frequently Asked Questions
Can I replace the ignition switch myself?
Yes, this is a very DIY-friendly job for someone with basic tools. The switch is located on the back of the ignition lock cylinder in the dashboard. The process involves disconnecting the battery, removing the lock cylinder (usually with a paperclip), unscrewing a bezel nut, and unplugging the switch from behind the dash.

The lock cylinder is the mechanical tumbler that your key fits into. The ignition switch is the electrical component that the lock cylinder turns. They are separate parts. If your key is difficult to turn, the problem could be in either part, but the electrical symptoms described above point to the switch itself.
Are there any recalls for this issue?
No, there are no specific recalls for the ignition switch on the 1963-1967 Chevrolet P10 Series. Any issues today are due to the age and wear of the original components.
Do I need special tools for the replacement?
No highly specialized tools are needed. You will need a paperclip or a small pick to release the lock cylinder, and possibly a special tool to unscrew the bezel nut from the dashboard, although careful use of needle-nose pliers can also work. Basic hand tools like a screwdriver and socket set are also required.
