Genuine OEM Thermal Fuse Relay 20A, Multi-Purpose Maxi Fuse Module, Replaces OE#443937105 (443-937-105), Compatible with Volkswagen CC/Passat/ID.4

Genuine OEM Thermal Fuse Relay 20A, Multi-Purpose Maxi Fuse Module, Replaces OE#443937105 (443-937-105), Compatible with Volkswagen CC/Passat/ID.4

• Part Type: Multi-Purpose Maxi Fuse / Thermal Fuse Relay Module (thermostat switch style); Rating: 20 Amp; Reference OE#: 443937105 / 443-937-105. Listed for Instrument Panel / Passenger Compartment applications. Designed as a circuit-protection device that interrupts current when the circuit load is too high; a practical replacement for worn, tripped, or heat-stressed fuse/relay modules.
• Install/Replace Tips: Confirm match by OE#443937105 (443-937-105) and the 20A marking on the part; do NOT up-rate amperage. Locate the correct cavity using the fuse box map in the owner's manual/service manual-this part is commonly listed under the Instrument Panel / Passenger Compartment fuse/relay panel (position varies by vehicle/trim). Turn ignition off and disconnect the battery before service; remove the old unit with proper puller/tools, inspect for corrosion or heat-damaged terminals, then seat the new module fully and verify affected functions. If the fuse trips again, diagnose the underlying short/overload before repeated replacement.
• Compatible with 1985-1988 Volkswagen Passat Syncro Fuse Box/Relay Plate Relay; Compatible with 1988-1992 Volkswagen Vanagon Fuse Box/Relay Plate Relay; Compatible with 1997-1999 Volkswagen Golf (USA) Fuse Box/Relay Plate Relay; Compatible with 2013-2017 Volkswagen CC Instrument Panel (Passenger Compartment) Relay; Compatible with 2012-2022 Volkswagen Passat Instrument Panel (Passenger Compartment) Relay; Compatible with 2021-2025 Volkswagen ID.4 Instrument Panel (Passenger Compartment) Relay. Always confirm the exact fuse/relay position by vehicle manual/VIN before ordering.
• Application Notes: Parts catalogs may describe this module as a multi-purpose/maxi fuse, thermostat switch, or thermo fuse. On some vehicles it is associated with power window / electric window lifter circuits (feature-dependent). If you see intermittent power, repeated fuse trips, or loss of function in the protected circuit, inspect the fuse/relay panel and wiring first. Best practice: keep a spare for the same fuse/relay box, and replace only after confirming the root cause to prevent repeat failure.
