The guide tube keeps the heater control cable correctly routed and supported, allowing it to move smoothly when the heater lever or control mechanism is operated. Proper cable movement is essential for opening and closing the heater flaps and maintaining reliable cabin heat control.

Functions
• Guides the heater control cable through the body or tunnel area
• Helps protect the cable from abrasion, dirt, corrosion, and damage
• Supports smooth heater cable movement
• Helps prevent cable binding, stiffness, or misalignment
• Assists correct heater flap operation
• Replaces missing, blocked, corroded, or damaged original guide tubes

Why Replace This Part?
The heater cable guide tube can wear, corrode, crack or become damaged over time, especially on older air-cooled Porsche models. If the guide tube is missing, bent or worn, the heater cable may not move smoothly, which can lead to stiff heater controls, poor cable movement or incorrect operation of the heating system. Replacing it with a Genuine Porsche OE guide tube helps restore the correct cable routing and supports reliable heater control operation.

When to Replace This Part

•   The original guide tube is missing or no longer supports the cable correctly
•   The car is undergoing heater system, body tunnel, or restoration work

Where it fits on the car
This guide tube fits within the heater control cable system. It is used to route and support the heater cable between the cabin heater control mechanism and the heater control components at the rear of the car. Exact position may vary depending on model year, heater control layout and manual or automatic heating equipment.
