The resistor allows the fan to operate with more than one speed setting. Make me believe that I … The radiator fan doesn't seem to be kicking in at all, even when it gets to 95 degrees. While driving, the temp meter would suddenly max out with the stop light flashing then return back to normal. Low Speed Fan resistor? They run hot and in this car they were mounted in the path of the air flow through the radiator/fan which while "hot" still kept the resistor from getting way too hot. Low Speed Fan resistor? Oe Ford F5rz8l603ac Radiator Cooling Low Fan Resistor NewOe Ford F5rz8l603ac Radiator Cooling Low Fan Resistor New ANCAP Crash Check - Ford Aim (LHD) Without having Aspect The passenger compartment held its form properly in the offset crash exam. They are accessible without removing the belly pan. Didn't work turning AC on, so I jumped the low speed relay (#21 for right side low - Bentley's has a typo for this) and it still did not operate. In the spring, I installed a 180 degree thermostat and adjusted the fan trigger temps to 196*F for low and 202*F for high with my handheld tuner, since my new thermostat now regulated engine coolant temp at 186*F at cruising speed. I have checked the obvious fuses in the box over the battery, and also checked the terminals on the two main fan relays but they all look good to me. Hey Carroll, I have a 1990 S2 spare fan resistor. In the case of this 2006 Gransport, the low speed turns on at 95 deg C and shuts off at 90 deg C. Conversely the high speed turns on at 100 deg C and shuts off at 95… After following all the advice on my ZX-# running very hot, I believe I have located the low speed fan resistor.It looks corroded. Your order may be eligible for Ship to Home, and shipping is free on all online orders of $35.00+. Contents[show] Resistor Location 1992 → 1995 On the 93-95 models, the resistors are directly beneath the left headlight, behind a rectangular body panel. It is plugged into the back of the fan, and it is a box-like contraption with springs. By rkctdwn, March 27, 2008 in Under the Hood. 7. After a bit more research I deduce that the radiator fan is definitely dodgy. I would also pull the relay, and look for indications of a short. Although fan1 (low speed) does not working, my car's engine temperature is always 90 degree. However, if the resistor fails, various problems with motor performance may occur. Sign in to follow this . The first problem on my ZETEC 2.0 is it always would have the highest speed fan come on when I turn on the AC but no low speed fan in car will run a temperature now that I've changed the pigtails and resistor the low speed fan comes on only when the AC is on but no highest speed fan and still no fan at all when the car's AC is not on any help with this problem with you really appreciated guys Order Cooling Fan Resistor for your vehicle and pick it up in store—make your purchase, find a store near you, and get directions. The Radiator Fan Resistor. it must not be short circuit I guess. A bad low-speed relay, fuse F2 blown or an open fan resistor would prevent the fan from operating on low speed—again, provided there were no wiring problems. Followers 0. To make sure I am looking at the low speed fan resistor. It may be easier to see from under the car. If not the resistor or wiring is bad. #04-01-37-006: Heater-Ventilation-Air Conditioning (HVAC) Hiss-Type Noise (Replace Low Speed Engine Cooling Fan Resistor) - (May 12, 2004) If I recall correctly the DRL resistor is on the outside of the frame. When the fan no longer ran at low speed -- but ran when the A/C was on or when the coolant temperature got to the high speed fan threshold -- the problem was this ballast resistor had failed. That might be why the high speed circuit is good. Cooling fan problems… round two: My low and high speed radiator fan modes had been working well since my last post above. Replace the faulty resistor and burned harness with a new genuine Ford unit. The brake pedal moved downwards 16mm. Recommended Posts. It seems my low speed fan on my Citroen C3 1.6 120 VTI 2012 doesn't come on, as I read the OBD coolant temp at around 97c, I even got to 102c (I think the high speed is working, but haven't seen it in action, just that I never overheat, and the temp … So right side radiator fan wasn't running the other day as the left side kicked on. Both fans were cycling on and off in low speed. Check here for special coupons and promotions. Radiator fan is not turning on, when A/C is switched on. The MAF has nothing to do with this issue. Then I checked the radiator fan resistor with multimeter. I bought it thinking that it was open. 6. 10-20 seconds jet engine mode --> off --> repeat when it's hot outside. Different speed settings can help the motor to efficiently handle heat problems. Now I have the high-speed fan set to 205 to help with cooling to make the car driveable and not overheat. It wont run on low speed. What I meant I the other comment, is that I confirm that the low speed fan resistor is bad, but I figured out that if you remove the low speed fan resistor, the high speed fan is activated at a lower temp and you dont have to be stuck in … When I leave my car idling for awhile (I have to at one of my jobs), it will run on high speed until I'm back underway with some moving airflow, and that's with the AC off (I turn the AC off when it's parked, and don't even use it much in city driving). This would happen a few times a day while driving or when starting the car. Also be sure to check the connector that comes from the body harness and connects to the resistor as it can be burned as well. My low-speed fan wasn't working, so I bypassed the resistor. Can anyone offer any advice on doing a bypass? The radiator fan on these cars has two separate speeds they can run at, LOW and HIGH. I have a 2005 R53 JCW and I believe it is plagued with the well documented resistor issue. Bypassing each relay (shorting pins 87 & 30) in turn showed the fan operated in both low-speed and high-speed modes (although of course now at the same speed). Fixed my situation where the low speed on the fan for the radiator wasn't working, directly affecting AC performance allowing correct pressure and then only the high speed fan kicking in. It is located behind the glove box. This resistor is pretty common to burn out and cause the low speed cooling fan to not work. If only the high speed is working then your radiator fan resistor …
