In a previous video https://www.youtube.com/watch?v=xHZVvHIbs9s&t I had a look at this Chevy Cruze and determined the cooling fan resistor to be faulty. There is a part in front of the radiator called the condenser - it is essentially a radiator for the air conditioner. If the fan comes on, then you should be OK. Usually the fan will only run when the vehicle is stationary or at low speeds, when airflow across the radiator needs to be increased. Researching the forum, symptoms match those of faulty cooling fan resistor & its pigtail wiring harness. If you want that information, you have to be careful to … Blower motor stuck on one speed . That may be why the 'low speed' circuit only needs a 30A fuse. What the heck. Order Cooling Fan Resistor for your vehicle and pick it up in store—make your purchase, find a store near you, and get directions. If the radiator fan is not working, it’s a serious problem. If you suspect your cooling fan resistor needs to be replaced, contact a professional mechanic. They are designed to only run when needed. The is a DIY by Bosterra in the old PPBB archives that also shows you how you can bypass the resistor by installing a temporary jumper cable between the … The resistors reduce power to the fan, so when the coolant is not quite at operating temperature, the selected … Your Chevy Spark‘s radiator fan has one of the most important jobs on the vehicle. If only the high speed is working then your radiator fan resistor is bad and needs to be replaced. Check here for special coupons and promotions. I have attached a picture of the wiring for the 3-speed electric cooling fan. The high speed circuit has no series resistor, the Fan Resistor, and needs a 50A fuse. See BS to pay $200 for a cable. Looked everywhere for the missing plug but its nowhere to be found. Jump to Latest Follow 1 - 11 of 11 Posts. The main job of the cooling fan is to draw ambient air across the cooling fins of the radiator to lower engine coolant temperatures. Resistor failure. Over time, one or both of your cooling fan resistors may become worn or fail due to everyday usage. Better flow and brand new. When it does fail, the fans either operate at high speed or not at all, cycling constantly in response to A/C high side pressure spikes. The best test of the cooling fan resistor and its associated wiring would be to pull K45 (aka RL15), then at its socket jumper from terminal 3 to terminal 5 - if both fans come on then F6, F2, R27 (the cooling fan resistor), and both fans are OK. Look for obvious signs of corrosion and burns from overheating. Diagnosing bad fan/resistor pack.
