The high speed circuit has no series resistor, the Fan Resistor, and needs a 50A fuse. Diagnosing bad fan/resistor pack. Over time, one or both of your cooling fan resistors may become worn or fail due to everyday usage. 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. If the fan comes on, then you should be OK. 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. A repair manual can tell you where its location is in your vehicle’s make and model. What the heck. A bad air conditioning relay will only keep the fans from running when the ignition is on and the air conditioning is turned on. The Fan Resistor is a current limiting resistor/ dropping resistor. I have attached a picture of the wiring for the 3-speed electric cooling fan. If only the high speed is working then your radiator fan resistor is bad and needs to be replaced.

If the resistor shorts or fails, it may … Then all … I can buy just resistor for same price as whole fan assembly. The easiest way to test these fans would be to plug the fan connector back in, remove the low and medium speed relays from the fuse box. The main job of the cooling fan is to draw ambient air across the cooling fins of the radiator to lower engine coolant temperatures. I bought the $20 resistor only and will see if I can get it to work. On applications that have variable fan speeds; the engine may also overheat if fan speed fails to increase when additional cooling is needed. Look for obvious signs of corrosion and burns from overheating. Jeep Commander Radiator Fan Not Working Causes. 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 … Now run your van up to temperature. The second problem is that the cooling fan resistor pack goes out. Your order may be eligible for Ship to Home, and shipping is free on all online orders of $35.00+. 1. The gt500 resistor is only $30. Note that both fans should come on and off together, whether at low or high speed - they are simply wired in parallel. If you want that information, you have to be careful to … Virtually all modern vehicles built today use electric cooling fans to help pull air through the radiator to keep the engine cool. In these designs, the fan switch is a little more complicated than on single-speed fan systems, but instead of supplying current to a relay, the switch feeds power to resistors. If $20 resistor doesn't cut it, ull just get whole new gt500 fan assembly for $209. The fan may work but it only runs at low speed; which may not be fast enough to prevent overheating. 15w Usb Discharge Load Tester Resister Resistor Pelican technical article mini r53 cooling fan resistor dodge journey radiator fan resistor replacement you r50 r53 cooling fan issue testing north american motoring i know my cooling fan resistor is dead the connector as well. It is the last line of defense between you and an overheating engine. Resistor failure. The sticker on the fan's spindle should tell you how many Amps the fan requires (mine are .20 A, it may vary). Cooling fans do not come on. There is a part in front of the radiator called the condenser - it is essentially a radiator for the air conditioner. It is responsible for controlling the blower motor’s fan speed. 1. Sounds like the same thing the 1.4 has. They are designed to only run when needed. Regular GT is $200. With a bad cooling fan relay, the driver's side cooling fan should still run in slow speed on high coolant temperature. Well, since you know the voltage coming from the PSU (12 V), and how many Volts you want the fan to recieve (lets say 9), then left hand side of the equation is 3 V. Basically you want your resistor to dissipate 3 V. Now, what you need to find out is what current your fans need. Jump to Latest Follow 1 - 11 of 11 Posts. We have these in stock just give us a call. Set the tool to read ohms (a measurement of resistance) and connect one of its probes to … The loom that its supposed to come out of is there and plugged into both fans. Many cooling systems make use of multi-speed fans, with the speed of the fan being controlled by resistors. Check the electric resistance of each of the resistor’s terminals with a multimeter. The blower motor resistor is an electrical component that is a part of the vehicle's heating and air conditioning system. However if your AC doesn't have a charge or it's too cold for the AC come on, or the cabin air fan isn't coming in- then the AC won't turn the fans on. Blower motor stuck on one speed . See BS to pay $200 for a cable. Symptoms Of A Bad Or Failing Cooling Fan Relay Yourmechanic Advice Cooling Fan Ford Focus Resistor Fixing Ford Focus Overheating With 1 Simple Trick You READ Grand Turbo Bbq Repair. Both fans should still in high run in fast speed if the ignition is on and a high coolant … Bad air conditioning relay. If it runs, it's almost certainly the resistor. Just because the radiator fan is not on does not mean that it is not working. It is the last line of defense between you and an overheating engine. The blower motor resistor is the component directly responsible for controlling the blower motor fan speed. Usually a bad or failing blower motor resistor will produce a few symptoms that can alert the driver of a potential issue.
