Door Control Module - 1991 300ZX Z32

The Nissan 300ZX Z32 utilizes a dedicated Door Control Module mounted behind the driver's kick panel to manage central locking and security functions. For 1990-1993 model years, locate OEM reference 25390-30P00, while 1994-1996 production transitioned to 25390-40P00 to accommodate revised security protocols. When harvesting from junkyards, prioritize vehicles with intact T-top seals, as water intrusion commonly corrodes the module's circuit board. Always verify the 8-pin connector configuration matches your chassis—early cars use a different pinout than late models. Test functionality by checking door lock synchronization and keyless entry response (if equipped). Installation requires transferring the metal mounting bracket, as interchange units often arrive without it. Avoid units from flood-damaged Z32s, as capacitor leakage is a frequent failure mode in these Nissan modules.
