Which one ? your van has three cooling fan relays an two fans ! The relays are located in the under hood fuse box # 9, 10 , 12 ! Relay Driven Dual Cooling Fan Diagnostics
The relay for your cooling fan is located Under hood, passenger side, front side of wheel well,
mounted in relay panel. I would also recommend testing or inspecting the coolant temperature sensor as well. it is located Under hood, passenger side, upper engine area, above
water pump, mounted in intake manifold
The fan temperature sensor,(Fan switch), is activated by the cooling systems coolant. Activated by it's temperature. It's located under the hood, passenger side, upper engine area, below the alternator, and mounted in the intake manifold. My money, is on the fan temperature sensor being bad.
The fan switch will usually be cylindrical shaped, the bottom is made of brass, and the top has a black insulator material, with a rubber type plug on top. The plug will have two wires coming out, going into the engine wiring harness. One wire is Black, one wire is Yellow.
The fan relay is located in a relay panel. I can't tell you at present, whether it's in a black plastic box, that you remove a cover to access it, or the relay is exposed. If it's in a plastic box, under the cover it should state what each relay is for, and where they are located inside the box.
The relay panel is under the hood, on the passenger side, front engine area, on the passenger side of the radiator.
there is a relay in the junction box under the hood if the cooling fan is not coming on when the engine is at 180 degress you can take the a/c clutch relay and switch it with the fan relay. if the fans come on it's the relay if it still doesn't it's the temp sensor on the fan unit....please rate this
