Ordered two of the resistors (I always like to have spare parts around) from Mouser ($15 each) and did the mod one evening. Categories . If your fan only runs at high speed when it is on it is probably the resistor that has failed. There are ways to bypass the AC controls to force the AC circuit to work and the fan to come on. The lower the resistance of the selected resistor in a pack, the higher the current that flows through the blower fan, and the faster the fan will turn. The reason its in the fan shroud is for cooling because it gets pretty hot. All the fan mod effectively does is relocate a replacement resistor somewhere more accessible. 4 core, Bee Cool aftermarket radiator installed. There are three different relays involved in the operation of the fans on the 2002 Zetec w/AC: K13 (aka RL8), the power hold relay; K45 (aka RL15), the low speed engine cooling fan relay, which feeds power to the fans thru the engine cooling fan resistor; and K46 (aka RL16), the high speed fan relay which feeds power to the fans on wires which bypass the cooling fan resistor. And then fix the fan. Answer. Worth checking but just one common cause for that particular problem. If I bypass it in theory ill just have two hi speed operations. 0 0 1.

I Have A 2001 Ford Focus Neither Cooling Fan Is Working Checked Rewire Radiator Fan Ecm Bypass You High Sd Engine Fan Override Mod You Ford Focus Cooling Fan Resistor You READ Kaifan Riverdale. The second problem is that the cooling fan resistor pack goes out. You're right in your assumption that it's the same fan which is being fed less power in the low speed phase. How do you bypass engine cooling fan resistor on 2002 ford focus? Asked by Wiki User. Then I just tried to bypass the thermo sensors all together to ground, but still only 6 Volts. You could probably use self-tapping screws as well but would need to be careful about hole size to ensure you don't twist off the heads during initial fitment. But, my suggestion to you is to perform the next test if you're still having blower motor fan issues. I mounted the resistor using some special heat sink grease on the aluminum motor mount for good heat conduction. When I first tested the resistor, it would get slightly warm when the fan ran, but it was cold in the garage and the fan quickly turned off. No pictures, but the fan needs to come out to fix the resister: bumper cover off, bumper off, radiator coolant drained and top pipe off, followed by removing the radiator and fan. In that case, the AC trick should work. If your fan only runs at high speed when it is on it is probably the resistor that has failed. Basically two wire coiled resistors one for slow speed one for medium and in the middle a diode which was direct power that runs the fan at full speed. Engine cooling fan problems only cause overheating in stop and go traffic, and low speed traffic below 45 mph or so. So the temperature sensor will get the resistance of 326 Ohms exactly by 80 degree Celsius. This resistor is not thermally protected well enough to withstand the power requirements of the fan, and tends to fail within a few tens of thousands of miles. MINI R53 models utilize an electronic cooling fan integrated into the cooling fan shroud. The cooling fan relay is normally located in either the underhood fuse and relay center or mounted to the electric fan assembly behind the radiator. In the highest speed state, the blower resistor is bypassed completely and the fan is connected directly to the car’s battery, which allows maximum current through the motor. The low speed circuit delivers power through a 1 Ohm resistor that is inside the fan motor housing. It has two relays in the fuse box. The key component of this temperature controlled fan circuit is Thermistor, which has been used to detect the rise in temperature.Thermistor is temperature sensitive resistor, whose resistance changes according to the temperature.There are two types of thermistor NTC (Negative Temperature Co-efficient) and PTC (Positive Temperature Co-efficient), we are using a NTC type thermistor. 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. The low speed fan is pretty quiet and you won't hear it in the car. People bypass the resistor to make the fan run at "high" speed all the time for better cooling. So i need to get a circuit to operate the radiator fan exactly by 80 degrees and above. Shortly after the Boxster had its resistor replaced (and a coolant tank replaced -- it finally let go) the Turbo's passenger fan quit working and I thought the same thing was wrong with it but the tech pointed out how protected the Turbo fan stuff was. Password: Register: Garage . I broke my resistor when installing a aux transmission cooler. The resistor is there to drop voltage and make the fan run in the low speed. Apr 23, 2013 #1 For an 86 GN. 76 Posts . I cut the 2 wires going into the resistor and spliced them together but still only 6 Volts. Never runs higher than 185. Location: Glasgow, Scotland. I did this on mine and I couldn't get the low speed fan to work, hence the resistor mod. Yes, I did this repair shortly after buying my '04 S about 4 months ago. If the cooling fan on your 1997 Ford Windstar isn't working, you may have a problem with your cooling fan dropping resistor. Most of the time it is close to the thermostat of the cooling system, or in some cases even inside of it. I have a broken cooling fan resistor and I can't seem to find a replacement number. Wiki User Answered . I bought a new fan from Euro Car Parts and it works fine: with a 12 year old fan I thought that fixing the resistor would just be the start, followed closely by fan motor etc I have aftermarket fans with no resister box and the radiator fan switch turns on the low side.

Remember, if the fan resistor has failed, the high speed setting for the fan will still work; the high speed fan will still come on at a higher temperature and stop the engine overheating. At the fan motor I have 6 volts at the blue wire and 12 at the black wire. #275 … Published by at 15 settembre 2020. I'd have to look into your overheating threads to figure out if this is causing your overheating. Granted I usually have the radio on when driving, but can you actually HEAR them? "Rubber Side Down" S.R. 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. Replaced it and new one blew when fan started to run. There are two different fan wiring circuits, one for cars up to mid 2003, which had the control relay in the fan assembly, and the later one with the control relay in the fuse box.
