It just sounds like a jet lol.Join our Mini Cooper Forums to talk about your new Mini. 30,196 Posts #10 • Aug 26, 2009. ingleton1 said: I guess the best … Can I bypass the resistor and wire - Answered by a verified Auto Mechanic . The resistor is there to drop voltage and make the fan run in the low speed. Rad fan resistor fix User Name: Remember Me? 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. So at 80 degrees the thermostat opens the gateway for the radiator coolant and it needs to switch ON the radiator fan. I'd have to look into your overheating threads to figure out if this is causing your overheating. 76 Posts . The fan resistor is $45, and that fixes the problem also. Want to master Microsoft Excel and take your work-from-home job prospects to the next level? Troubleshooting. Posting your exact issue in it's own thread will get the most responses, and searching this section for more detailed cooling fan information might be useful. Upon investigation I found both coil type wire resistors had broken hence no slow speed with air con on and no medium speed at about 88 degrees. So i need to get a circuit to operate the radiator fan exactly by 80 degrees and above. 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.

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. Join Date: Mar 2010. 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. This video will show you how to find and fix that part. Published by at 15 settembre 2020. Engine cooling fan problems only cause overheating in stop and go traffic, and low speed traffic below 45 mph or so. I have a post in the "Parts Wanted" section, asking for one. 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. 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. Registered User . 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. How do you bypass engine cooling fan resistor on 2002 ford focus? Thread starter Hyboost; Start date Apr 23, 2013; Hyboost Hyboost. Where is the temperature sensor located? Can I bypass the radiator cooling fan resistor - 1990 Buick LeSabre Replaced it and new one blew when fan started to run. This thread from 2011 only addresses checking the low speed fan resistor, one possible reason for no low speed operation only. You bypass the resistor by jumping it with a piece of wire, run a jumper wire from one end of the reisistor to the other end of the resistor, the fan will now run on "high speed all the time. I broke my resistor when installing a aux transmission cooler. The low speed circuit delivers power through a 1 Ohm resistor that is inside the fan motor housing. Top Answer. Apr 23, 2013 #1 For an 86 GN. "Rubber Side Down" S.R. There is a resistor in the wiring and attached to the shroud that will control the speed of the fan.
Ordered two of the resistors (I always like to have spare parts around) from Mouser ($15 each) and did the mod one evening. MINI R53 models utilize an electronic cooling fan integrated into the cooling fan shroud. The second problem is that the cooling fan resistor pack goes out. 4 core, Bee Cool aftermarket radiator installed. People bypass the resistor to make the fan run at "high" speed all the time for better cooling. Categories . 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. So the temperature sensor will get the resistance of 326 Ohms exactly by 80 degree Celsius. I cut the 2 wires going into the resistor and spliced them together but still only 6 Volts. 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.
