What Does the Heater Cable Do?

A correctly functioning heater cable ensures:

• Smooth operation of the heater control
• Accurate heater flap movement
• Reliable cabin temperature adjustment
• Correct travel of the heater mechanism
• Consistent operation of the factory heating system

Common causes of failure include:

• Cable stretching
• Frayed inner cable Internal corrosion
