It does NOT fit E46 Sedan or Touring (4-door) models such as 320i, 323i, 325i, 325xi, 328i, 330i, 330xi — those vehicles use a different switch (part# 61316902184).

• PART NUMBER COMPATIBILITY: Directly replaces OEM part numbers 61316902183, 61316902175, 61318381509, and 61318381517. This is the master power window switch located on the front left (driver) door panel. It controls both the driver and passenger windows from the driver's position. The switch features the correct 7-pin connector configuration and button layout matching the factory unit. Cross-reference numbers: 901-525, 1S13016.
• ENGINEERED FOR RELIABILITY: Constructed from automotive-grade ABS plastic housing with gold-plated internal contacts for consistent electrical conductivity. The push-button mechanism is rated for over 100,000 cycles, matching OEM durability standards. The internal circuit board uses quality solder joints and corrosion-resistant terminals that maintain reliable electrical connections over years of daily use. Each switch is bench-tested for proper function across all window positions (up/down, express, and lock) before packaging.
• CONFIDENCE IN YOUR PURCHASE: A failed power window switch is one of the most common electrical issues on aging BMW E46 Coupe models. Symptoms include: windows not responding to button press, intermittent operation, windows moving slowly, or the window lock function not working. This replacement switch restores full functionality to both driver and passenger windows from the driver's door. At a fraction of the BMW dealership price ($100+), this aftermarket switch delivers identical performance and plug-and-play installation. The E46 M3, 325Ci, and 330Ci remain highly sought-after enthusiast vehicles — keeping all electrical systems functional maintains both driving enjoyment and resale value.
• EASY INSTALLATION: Direct plug-and-play replacement taking 10-15 minutes with basic tools. Steps: (1) Gently pry up switch panel from driver's door armrest using plastic trim tool — start from rear edge; (2) Disconnect electrical connector from back of old switch by pressing release tab; (3) Take out old switch from panel bezel; (4) Test-fit replacement switch in bezel — if slightly tight, lightly sand ends of switch body with fine-grit sandpaper (220-grit) until it slides in; (5) Connect electrical connector to replacement switch until it clicks; (6) Press switch panel back into door armrest until all clips engage; (7) Test all window functions before reassembly.
