Diagram Ref No 2
Available for the left and right sides under references 90121105122/1 and 90121105222/1, these clamps perform two important functions: they help secure the upper heater hose in its correct position and provide a locating point for the heater control cable.
Designed as an OE-style replacement, the clamps are suitable for restoring ageing, corroded, bent or missing original hardware and help maintain the correct factory routing of the heating system components.
What This Product Does:
The Porsche heating system relies on heater hoses to carry warm air through the vehicle and control cables to operate the heater flaps and regulate airflow.
These clamps help keep both systems correctly positioned by:
- Securing the upper heater hose
- Supporting and locating the heater control cable
- Preventing excessive movement of the hose and cable
- Maintaining correct cable and hose routing
- Reducing the risk of rubbing against surrounding components
- Helping the heater controls operate consistently
- Keeping the heating-system installation neat and securely mounted
Although a relatively small component, correct clamping is important because movement or incorrect routing can place unnecessary strain on hoses, cables and their attachment points.
Symptoms Of Wear Or Failure:
After many years of heat exposure, vibration, moisture and road contamination, original heater clamps can corrode or become mechanically damaged.
Common signs that replacement may be required include:
- Visible rust or corrosion
- Bent or distorted clamp sections
- Cracks or broken mounting points
- Missing clamp hardware
- Clamp no longer tightening securely
- Heater hose moving excessively
- Heater cable hanging loose or incorrectly routed
- Rattling or vibration from unsecured components
- Heater cable rubbing against nearby components
- Chafing or marking on the heater hose
- Increased stiffness or inconsistent operation of the heater controls caused by poor cable routing
- Components found loose or deteriorated during restoration or servicing
A damaged clamp should also be replaced if it can no longer hold the hose or heater cable firmly in the intended position.
Why Replacement Matters:
- Correct routing and secure mounting are important to the operation and longevity of the heating system.
- If the heater hose is allowed to move excessively, it may rub against surrounding components, increasing the risk of wear or damage. An inadequately supported heater cable can also become misaligned, chafe or develop unnecessary friction, which may affect the feel and operation of the heater controls.
- Replacing a corroded, damaged or missing clamp restores the intended mounting arrangement and helps protect the associated hose and control cable from unnecessary movement and wear.
- For restoration projects, replacing deteriorated mounting hardware also helps return the heating system to a more complete and factory-correct installation.

The heater cable transfers movement from the cabin heater control lever to the heater control mechanism. When the control is operated, the cable opens or closes the heater flaps / control boxes, allowing warm air from the engine heating system to be directed into the cabin.
Functions
• Connects the heater control lever to the heater control mechanism
• Transfers cabin control movement to the heater flaps / heater boxes
• Helps regulate warm air flow into the cabin
• Supports correct heater and demister operation
• Replaces stretched, seized, frayed, or damaged original heater cables
• Helps restore smooth heater control adjustment
• OE Match replacement for heating system repair or restoration.
Why Replace This Part?
Heater cables can stretch, seize, corrode, fray, kink, or become stiff over time due to age, moisture, heat, and long-term use. A worn cable may prevent the heater flaps from opening or closing correctly, causing poor cabin heat, limited demister performance, uneven heater control, or excessive lever resistance. Replacing the heater cable helps restore proper heating system adjustment and reliable cabin comfort.
When to Replace This Part
• The heater cable is stretched, seized, frayed, kinked, or corroded
• The heater control lever feels stiff or loose
• The heater flaps do not open or close correctly
• Cabin heating is weak, inconsistent, or difficult to control
• Demister performance is poor due to heater control issues
• The heater boxes, control flaps, or heater levers are being serviced
• The vehicle is undergoing classic Porsche interior or heating system restoration.
Where it fits on the car
This heater cable fits within the cabin heater control and rear heater control system. It runs from the heater control lever area to the heater control mechanism according to the factory cable routing.
