If the cigarette lighter in your Porsche 993 has stopped heating, popped out, or looks broken, you likely need a replacement. But ordering the wrong part can be frustrating and expensive. This guide provides the exact OEM part number for the Porsche 993 cigarette lighter, explains the components, and helps you install the new part correctly.
The OEM Porsche 993 Cigarette Lighter Part Number
The original equipment manufacturer (OEM) part number for the cigarette lighter assembly in a Porsche 993 (1995–1998 911) is 964.652.614.00. This number applies to both the lighter element (the heating coil portion) and the socket assembly. However, note that some replacements are sold as a complete unit including the knob and heating element, while others are sold separately. Always verify with a Porsche dealer or trusted supplier using this part number to ensure compatibility.
Variations and Supersessions
OEM part numbers can sometimes be superseded. For instance, the original number 964.652.614.00 may have been updated to 964.652.614.01 or later. Check with the supplier for the most current supersession. The same part number is used across many Porsche models of the era, including some 964 and 993 variants, but the 993-specific application is consistent.
Understanding the Components
The cigarette lighter in a Porsche 993 consists of three main parts: the knob (the part you push in), the heating element (the metal coil that gets hot), and the socket (the metal cylinder that houses the assembly). Most replacement assemblies include the knob and element. The socket is usually part of the dashboard wiring and rarely needs replacement unless physically damaged.
Lighter Element vs. Socket
If your lighter doesn't heat up, the problem is almost always the element or the fuse. The element is the part that glows red. The socket itself is just a holder and electrical contact point. If the lighter falls out or sits loosely, the socket may be worn. The socket is not typically sold separately for the 993; you would need the complete assembly.
How to Confirm You Have the Right Part
Before ordering, remove your existing cigarette lighter by gently prying the knob out. Compare the shape and size with the replacement. The 993 lighter has a cylindrical shape with a metal outer collar and a black plastic knob. Measure the diameter: it should be about 21mm. Check for any writing on the old part that might indicate a different number.
Model Year Differences
The Porsche 993 ran from 1995 to 1998. The cigarette lighter design remained the same across all model years. However, if you have an early 1995 model, there is a slight chance it uses the older 964 part number (964.652.614.00 – which is actually the same). No changes were made during production.
Tips for Replacing the Cigarette Lighter
Replacing the lighter is straightforward. Use a trim removal tool to gently pop the socket out of the dashboard if you need to access the wiring. Most replacements simply push in. Follow these steps:
- Disconnect the battery negative terminal to avoid short circuits.
- Remove the old lighter by pulling straight out. If it's stuck, rock it gently.
- Unplug the electrical connector from the back of the socket if you're replacing the entire assembly.
- Plug in the new assembly and push it into the dash until it clicks.
- Test by pushing the lighter in and waiting 10–15 seconds. It should pop out when hot.
Tools Needed
- Trim removal tool (or flathead screwdriver wrapped in tape)
- Flashlight
- Needle-nose pliers (optional for stubborn connectors)
Common Issues and Solutions
Lighter Doesn't Heat
Check the fuse first. The cigarette lighter fuse in the 993 is typically a 15A fuse in the driver’s side footwell fuse box. If the fuse is good, replace the lighter element.
Lighter Pops Out Too Quickly
This indicates the heating element is not making good contact. Sometimes bending the metal tabs on the socket slightly inward can fix this. If not, replace the assembly.
Lighter Gets Stuck
Often caused by debris or corrosion. Clean the socket with electrical contact cleaner. If that doesn't work, replace the assembly.
Final Recommendation
For a direct fit, order the OEM part 964.652.614.00 from a Porsche dealer or a reputable online supplier that specializes in OEM German car parts. Avoid generic aftermarket lighters that may not fit properly or last as long. If you want to be absolutely sure, remove your old lighter and compare it visually with photos provided by the supplier. The installation is simple, and you'll have a perfectly working lighter in less than 30 minutes.
