Rad fan resistor fix I simply refused to pay £67 per side to solve the issue so decided to find an alternative way to fix them. I'd put 12 volts to the blower and see what happens. HOWTO: Install a Cooling Fan Bypass Switch Written by Wild Weasel. Get it as soon as Tue, Dec 8. These are: The Low Speed Fan Control Relay. 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 two relays that control the fan. The electric cooling fan system uses the following core components: Two electric cooling fan motor assemlies Fan motor 1 (located on the driver side of the radiator). The switch on the back of the tstat housing activates the high side. I got things working by jumping out the relays but I can not get 12 volts to the fans. Try not to break the funky bottom cover as it keeps the passenger from getting their feet or toes up into the moving blower wheel. 7. If you get a resistor with larger leads, you can use butt connectors and crimp it together just as I instruct for the diode. BTW, you can get the ATC blower control unti for much less than $70+. One solution proposed on a British forum is the installation of a high power resistor to bypass the fan's defective internal resistor. Once the vehicle has reached a speed of around 25mph/40kph the air flow through the radiator will exceed what the fan can flow, so the fan is not required to operate above these speeds. Radiator Fan Resistor, Ford, Mercury, Each. Or maybe pull one from junkyard if possible for like $10 maybe? I have aftermarket fans with no resister box and the radiator fan switch turns on the low side. If it struggles to turn, suspect both the fan and control module are cooked, like it was with mine when the fan developed so much friction from the motor going out that it cooked the control module. Estimated Ship Date: 12/4/2020 if ordered today. The leads were very small on the resistor I used so I soldered it to the wire. Most of the time it is close to the thermostat of the cooling system, or in some cases even inside of it. Bypass ECU :: Radiator Fan Control Switch. $33.95. Problems going on with my fans, I suspect maybe related to the 85/95 thermo sensors in the radiator. FREE Shipping on orders over $25 shipped by Amazon. I elected to try this modification, since the fans were still working fine on high speed. Long ext on the sockets plus a swivel would really help. Buy Heater Blower Motor Fan Resistor Air Conditioning Replacement Parts ECCPP fit for 2002-2005 Chevrolet Avalanche 1500/2002-2005 Chevrolet Avalanche 2500/1999-2007 Chevrolet Silverado 1500: Blower Motors - Amazon.com FREE DELIVERY possible on eligible purchases Where is the temperature sensor located? Warm idle after radiator fan kicked in: 10.35 - 10.55 volts Acceleration and boost: ~10.5 volts After taking the measurements above, the voltage at the battery during warm idle was 13.72 volts, which is normal for a properly functioning alternator. Those relays are located on the bottom row of the relay tray in the left footwell, just above the fuse panel. If not the resistor or wiring is bad. 2006 GC SE 3.3L SnG. I have no blower at any speed 01 T&C Ltd with ATC. The first part of the installation is to install the electric fan to your radiator, and remove the mechanical fan. The "bypass mod" did not improve voltage to the pump for me. Eurovans require 2, Vanagons require 1. A relay kit, our part number CCFKRL, will include everything you need to properly wire up your electric cooling fans, with the exception of additional wiring needed to complete all of the circuits. JavaScript is disabled. MINI R53 models utilize an electronic cooling fan integrated into the cooling fan shroud. Designed to restore the radiator fan to proper operation by reliably controlling fan speeds, Dorman's Engine Cooling Fan Motor Relay provides long lasting protection against overheating. Would it be safe to shunt/jumper/short the blower motor resistor, provided I am content with having the fan on full blast? E30 radiator temp sensor and aux fan resistor disintegrated, can they be bypassed? Whats people lookup in this blog: Cooling Fan Resistor Test; Ford Focus Cooling Fan Resistor Test If your fan only runs at high speed when it is on it is probably the resistor that has failed. If that's the case, do the fan first and check with your current module. So both my rad fans wouldn't run on low speed due to the resistors being knackered. If any of the individual steps or switches fail, it will disable the cooling fans from operating on that speed setting. Next connect the jumper between M2 30 and V2, the passenger fan … I should be able to bypass the resistor and get 12 Volts. 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. Many of us have done the same and its not very hard. The reason its in the fan shroud is for cooling because it gets pretty hot. If I ever need to buy that thing, I will not buy it if broken (sheared?). GMC Yukon Heating & Cooling at 1AAuto.com. Order Cooling Fan Resistor for your vehicle and pick it up in store—make your purchase, find a store near you, and get directions. It is my understanding that at the highest fan speed, there is 0 ohms resistance upstream of the blower motor. Here is one from ebay from $22, Blue and back to black jump togather on the back of the resistor I signed in to help yah so I hope all goes well goodluck, That is the blue and black wire to black wire use a paper clip if you need to it want melt and want short out cause its stiff. I am looking for some details on an alternative radiator fan resistor to the expensive OEM version. Next connect the jumper between M1 30 and V1, the drivers fan should run at low speed. Part Number: RNB-902-219. You could connect the wire from the t-stat switch to the green wire on the radiator switch and the radiator switch will activate both high and low relays giving you a high only outcome. hi negative (goes to ground on M/T, switched on/off to ground by the 5th radiator fan relay LO2 on A/T) = blue/green So, I'd wire the 12v wires for both the high and low fan circuits together. Well, it might be ok then, but if I remove 10 bolts, I will later install 10 bolts, not matter what.

All that circuit does is provide a low fan speed operation, Both hi and low speed use identical relays except one goes to the fan and the other goes to this circuit which is a honking resistor and a thermal cutout. So i am finishing up a rebuild and now dealing with the cooling system. I didn't have the swivel when I went, thus it took another 30mins to extract the blower fan. Replace the module only if the new fan still fails to spin. Would it be safe to shunt/jumper/short the blower motor resistor, provided I am content with having the fan on full blast? The blowers in a 4th gen are a RARE think to find at a pull-a-part place. It's a PITA to get out, even on a hot day in a van that is paced tight next to other vans. 6.
