1-1355350-1 / 1-1355349-1 Automotive 18-Pin Connector — VW Air Conditioning Panel & Amplifier
The 1-1355350-1 (female) and 1-1355349-1 (male) are 18-pin automotive connectors from TE Connectivity used in Volkswagen air conditioning control panel and audio amplifier wiring harness applications. These connectors interface the climate control module and audio amplifier with the vehicle’s body wiring harness, carrying a mix of control signals, CAN bus communication, power, and ground circuits. The 18-pin configuration provides sufficient circuit density for modern dual-zone climate control systems and premium audio amplifiers.
Climate control module connector failure is a common cause of intermittent AC operation, incorrect temperature display, and CAN bus communication faults on VW vehicles. The connector sits in the instrument panel — a location subject to heat from the HVAC system, vibration from the dashboard, and occasional moisture from condensation or spilled liquids.

VW Climate Control Module — Circuit Requirements
- 18-pin for dual-zone climate control — modern dual-zone AC systems require circuits for: compressor request, blower motor speed control, temperature sensor inputs (driver/passenger/evaporator/ambient), actuator motor control (air distribution, temperature blend), CAN bus, power, and ground
- Audio amplifier interface — premium VW audio systems (Dynaudio, Fender, Beats) use a dedicated amplifier module connected via a multi-pin connector carrying speaker outputs, power, ground, and CAN bus communication
- TE Connectivity OEM standard — TE connectors are used across VW Group (VW, Audi, Skoda, SEAT) instrument panel wiring harnesses; the 1-1355350-1/1-1355349-1 is manufactured to VW mating dimensions
Typical Applications
- VW climate control module connector repair
- VW audio amplifier wiring harness replacement
- Instrument panel wiring harness repair on VW platforms
- Dual-zone AC control panel connector replacement
Frequently Asked Questions
Q: What symptoms indicate a faulty AC control panel connector?
Common symptoms include: AC not responding to control panel inputs, incorrect temperature display, blower motor running at fixed speed, CAN bus communication faults (U-codes) related to the climate control module, and intermittent AC operation that improves when the dashboard is warm. Inspect the connector for corrosion, bent terminals, or loose fit. A scan tool can identify specific climate control module DTCs that point to the affected circuit.
Q: Which VW models use 1-1355350-1 / 1-1355349-1?
These connectors are used across multiple VW models including Golf Mk6/Mk7, Passat B7/B8, Tiguan Mk1/Mk2, Polo Mk5/Mk6, and related SEAT/Skoda platforms. Consult the VW ETKA parts catalog with your vehicle’s VIN to confirm the exact connector part number for your specific model and equipment level (standard vs. premium audio, single-zone vs. dual-zone AC).
Q: Can a faulty amplifier connector cause audio distortion or no sound?
Yes — a corroded or loose amplifier connector terminal causes increased resistance in the speaker output or power supply circuit, resulting in distortion, reduced volume, or complete loss of audio on affected channels. CAN bus terminal corrosion can cause the amplifier to lose communication with the head unit, resulting in no audio output at all. Inspect the amplifier connector before replacing the amplifier module.
