Aftermarket 911-615-103-02 A/C and Horn Relay with Integrated 20-Amp Fuse

The Aftermarket 911-615-103-02 is a replacement multi-function relay featuring an integrated 20-amp fuse, designed to control critical electrical circuits including the air conditioning (A/C) compressor, horn, and related accessory systems on classic Porsche 911 and 930 models.

This relay serves as an essential switching component in the vehicle's electrical system. When the relay fails, it can prevent the A/C compressor from engaging, disable the horn circuit, or cause other accessory functions to stop working. Replacing a faulty relay with this aftermarket unit restores proper operation to these systems.

Key Features:

• Integrated 20-amp fuse for circuit protection
• Controls air conditioning (A/C) compressor clutch engagement
• Also used for horn and other accessory electrical circuits
• Aftermarket replacement for OEM Porsche part number 911-615-103-02
• Drop-in replacement — no modification required

This is an aftermarket replacement relay manufactured to fit the same specifications and connector footprint as the original Porsche component, making it a cost-effective solution for restoring full A/C and horn functionality.
