Toyota Highlander / Corolla / Prado / RAV4 2-Pin 4.8mm A/C Cooling Fan Waterproof Connector – OEM 90980-11237 / 7283-8221-40
Direct OEM-specification replacement for the Sumitomo 2-pin waterproof wire harness connector used on air conditioning (A/C) cooling fans across Toyota Highlander, Corolla, Prado, and RAV4 platforms. Cross-references Sumitomo / Toyota OEM part numbers 90980-11237 and 7283-8221-40. Uses the 4.8mm contact series in black nylon housing with waterproof sealing — the 4.8mm series is Toyota’s standard high-current connector for cooling fan motors where the connector must carry the full motor current (typically 10–25A) in an underbonnet environment.
The 2-pin A/C cooling fan connector is located in the engine bay, directly on the condenser fan motor or radiator fan motor. It is exposed to heat from the engine and A/C condenser, road spray, and vibration. A failed connector causes the A/C cooling fan to stop operating, leading to A/C system overheating — the A/C compressor shuts down as a safety measure when the condenser temperature rises above the threshold. On Toyota Highlander and Prado, the A/C fan connector is also frequently damaged during front bumper removal for radiator or condenser replacement.

Q: My Toyota Highlander A/C stopped working in traffic — could it be the fan connector?
A: Yes. A corroded or open 2-pin A/C fan connector is a common cause of A/C failure at low speed on Toyota Highlander. The condenser fan is critical for A/C performance at low vehicle speeds when there is insufficient airflow through the condenser. Inspect the connector (OEM 90980-11237) before replacing the fan motor or A/C compressor.
Q: Are terminals included?
A: Yes, terminals are included with all variants.
