8-Pin 174044-2 1.0mm Unsealed Male & Female Connector – Window Lifter Assembly Harness

Direct-fit replacement for AMP/TE Connectivity part number 174044-2, an 8-pin 1.0mm pitch unsealed connector used for window lifter motor, door module, and body control harness connections. The miniature 1.0mm pitch provides high-density signal connections for multi-function door module circuits in space-constrained door panel locations.

Window Lifter Pin Assignment Reference (8-Pin)

Note: Pin assignment varies by vehicle platform. Always verify with vehicle-specific wiring diagram before installation.

Compatible Applications

• Window lifter motor assemblies: Multi-function door module harness connector (interior, unsealed location)
• Body control module (BCM) sub-harness: Door module data and power distribution connector
• General: Interior door panel harness junctions requiring 8-pin 1.0mm pitch connectivity

Unsealed Design – Why 174044-2 Is Not Waterproof

The 174044-2 is an unsealed connector designed for interior door panel locations where moisture ingress is not expected. It is not suitable for exterior or exposed locations (door mirror, exterior lighting, underbody). For exterior door applications, use a sealed IP67/IP68 equivalent. Installing an unsealed connector in a wet location will cause terminal corrosion and intermittent window operation faults.

Diagnosis – Window Lifter Faults

• Window operates in one direction only: Inspect Pin 3 (UP) or Pin 4 (DOWN) signal – an open circuit on one signal line causes single-direction operation
• Anti-pinch not working: Inspect Pin 5 (anti-pinch sensor) – a faulty connection disables the safety function and may cause window to trap objects
• Window initialisation required after battery disconnect: Normal behaviour for LIN bus window modules – fully open and close the window to re-initialise the position sensor
• Common fault codes: B1000 (Door Module), B2477 (Window Motor Circuit) – check connector before replacing motor assembly

FAQ

Q: Is 174044-2 the male or female connector?
A: This listing includes both male and female housings (174044-2 male + mating female). Both are required for a complete harness repair.

Q: Why does my window need to be re-initialised after replacing the connector?
A: LIN bus window modules lose their position calibration when power is interrupted. After connector replacement, fully open and close the window 2–3 times to re-initialise the Hall sensor position memory.
