Fitment Details

Compatible with 1996-1997 BMW 328is and 1987-1988 Nissan 200SX. Fits 1996-1997 BMW 328is, N/A. Fits 1987-1988 Nissan 200SX, N/A.

How This Switch Is Used

  • Restores cooling fan control when the original switch no longer triggers properly
  • Addresses fan operation that stays on too long or does not activate at the correct temperature
  • Helps correct overheating concerns tied to a failed fan switch
  • Supports proper electrical signaling in the cooling system

Installation Notes

Verify the 16mm x 1.50 thread size, 12-volt electrical system, connector style, and harness routing before installation. The TS-129 uses a female rectangular connector with male blade terminals and a plug-in harness, so matching the OE connector layout is important for proper fitment on BMW 328is and Nissan 200SX applications.
