Specs & key use: 12V auxiliary engine cooling fan relay module (typical catalog rating 30A), 5-terminal / 3-connector design; used as a Cooling Fan Motor Relay / Radiator Fan Relay / A/C condenser fan relay in the cooling-fan control circuit (varies by vehicle). Bracket-mounted relay-module style—confirm your mounting points and plug shapes match. Helps restore proper fan switching when an old relay causes fan not running, fan running continuously, or overheating warnings. OE reference: 9442933; cross refs commonly listed as 3523872 and 1398845—match OE number + connector/terminal layout on your original relay before ordering.
Install tips (confirm in your vehicle manual): disconnect the negative battery cable, then locate the cooling fan relay module. On many compatible applications it is NOT in the main fuse box—often found at the front of the engine bay under the upper plastic cover above the radiator, connected by 3 plug connectors. Unplug connectors straight out (corrosion can make them tight), transfer any clip/bracket as needed, install the new relay with the same orientation as the original, and reconnect until fully seated. Final checks: verify terminal count (5) + plug shapes match, then start the vehicle and confirm cooling fan cycling and A/C fan operation (if equipped).
