Ordered two of the resistors (I always like to have spare parts around) from Mouser ($15 each) and did the mod one evening. There are ways to bypass the AC controls to force the AC circuit to work and the fan to come on. Never runs higher than 185. 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. Worth checking but just one common cause for that particular problem. This revealed the cooling fan resistor pack. 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. If the cooling fan on your 1997 Ford Windstar isn't working, you may have a problem with your cooling fan dropping resistor.

Top Answer. The second problem is that the cooling fan resistor pack goes out. Replaced it and new one blew when fan started to run. 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. Can I bypass the radiator cooling fan resistor - 1990 Buick LeSabre 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 This video will show you how to find and fix that part. I should be able to bypass the resistor and get 12 Volts. I mounted the resistor using some special heat sink grease on the aluminum motor mount for good heat conduction. Asked by Wiki User. Can I bypass the resistor and wire - Answered by a verified Auto Mechanic . #275 … If your fan only runs at high speed when it is on it is probably the resistor that has failed. We use cookies to give you the best possible experience on our website. I did this on mine and I couldn't get the low speed fan to work, hence the resistor mod. 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. Yes, I did this repair shortly after buying my '04 S about 4 months ago. So both my rad fans wouldn't run … In that case, the AC trick should work. Location: Glasgow, Scotland. 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. 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. Apr 23, 2013 #1 For an 86 GN. This thread from 2011 only addresses checking the low speed fan resistor, one possible reason for no low speed operation only.

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. Answer. 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 next step indirectly tests the blower switch on the A/C Heater control panel by bypassing the blower resistor with a jumper wire: TEST 2: Using A Jumper Wire To Bypass The Blower Resistor. At the fan motor I have 6 volts at the blue wire and 12 at the black wire. How do you bypass engine cooling fan resistor on 2002 ford focus? I cut the 2 wires going into the resistor and spliced them together but still only 6 Volts. There is a resistor in the wiring and attached to the shroud that will control the speed of the fan. 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 low speed circuit delivers power through a 1 Ohm resistor that is inside the fan motor housing. 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. The best … 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. The resistor is there to drop voltage and make the fan run in the low speed. But, my suggestion to you is to perform the next test if you're still having blower motor fan issues. Granted I usually have the radio on when driving, but can you actually HEAR them? 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. I have a one fan system. Most of the time it is close to the thermostat of the cooling system, or in some cases even inside of it.
