10-20 seconds jet engine mode --> off --> repeat when it's hot outside. The brake pedal moved downwards 16mm. Your order may be eligible for Ship to Home, and shipping is free on all online orders of $35.00+. However, if the resistor fails, various problems with motor performance may occur. Inspecting all three components can solve half of your problems. Spliced with a new wire and problem solved. The MAF has nothing to do with this issue. It must be the same type. 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. Next connect the jumper between M2 30 and V2, the passenger fan should run at low speed. Make me believe that I … Most of the problems with the fan that have been documented on the forums are to do with the resistor pack on the 1st stage fan control and mine definietly wasnt coming on with the air-con as it should. The radiator fan on these cars has two separate speeds they can run at, LOW and HIGH. To make sure I am looking at the low speed fan resistor. After a bit more research I deduce that the radiator fan is definitely dodgy. It wont run on low speed. I have my tune set for 195F low-speed fan and 210 High speed. I bought it thinking that it was open. I might rewire with a heavier wire gauge later. You should be able to have two speeds (low and high and you will be able to tell the difference as high is like huricane force). 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). The HI and LOW cooling fan relays ... gets .While cool your fan moves slowly. and it's pins were short circuit. Ive checked the fuses and the relays and all good. 1996 → On the 1997 model the resistors are located under the lip of the front bumper near the belly pan latch. If only the high speed is working then your radiator fan resistor … Check here for special coupons and promotions. 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. 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… My low-speed fan wasn't working, so I bypassed the resistor. It is 0.6 ohms x 70 watts. I have a 2003 cooper s r53. So right side radiator fan wasn't running the other day as the left side kicked on. Hey Carroll, I have a 1990 S2 spare fan resistor. Different speed settings can help the motor to efficiently handle heat problems. Check for voltage at the radiator fan connector and then check the resistance across the resistor. 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. And I checked the fuse of resistor, but it was ok. 7. Radiator fan is not turning on, when A/C is switched on. After following all the advice on my ZX-# running very hot, I believe I have located the low speed fan resistor.It looks corroded. 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 Relay in the TIPM (K11) labeled “Radiator Fan Low” The dual relays over by the brake master cylinder labeled “Fan Relays” on the internet (Mopar Part 56055666AB) The lack of a P069X style code being thrown led me to believe this was a unique problem with only the “high” speed part of running the fan. The low speed relay runs thru the fan resistor, the high speed relay bypasses it. 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. That might be why the high speed circuit is good. High speed fan worked fine while checking. ... i have a burnt out resistor on my slow speed fan on my 08 MCS but the fan itself is totally fine. Next connect the jumper between M1 30 and V1, the drivers fan should run at low speed. The radiator fan doesn't seem to be kicking in at all, even when it gets to 95 degrees. Low Speed Fan resistor? 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. Although fan1 (low speed) does not working, my car's engine temperature is always 90 degree. I would also pull the relay, and look for indications of a short. Followers 0. It is located behind the glove box. It is plugged into the back of the fan, and it is a box-like contraption with springs. Then I checked the radiator fan resistor with multimeter. Now I have the high-speed fan set to 205 to help with cooling to make the car driveable and not overheat. They are accessible without removing the belly pan. Testing the fan … It may be easier to see from under the car. This resistor is pretty common to burn out and cause the low speed cooling fan to not work. A lot of manufacturers use cooling fan resistors in order to offer multiple fan speeds on a single fan assembly or to control dual fans. I jumped the high speed (#22 for right side high) and the fan worked so it must be the low speed Resistor. If not the resistor or wiring is bad. 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. Cooling fan problems… round two: My low and high speed radiator fan modes had been working well since my last post above. Sign in to follow this . A quick visual inspection established that the low-speed relay and resistor were in place and that fuse F2 appeared to be good. When the engine compartment temperature reaches a certain level, the main radiator fan is supposed to come on, and since the ps cooling fan is also wired into that, it is supposed to also come on. Low Speed Fan resistor? If the two speeds are working then everything in the wiring is good (fan, relays, wires, plugs etc). 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 … Contents[show] Resistor Location 1992 → 1995 On the 93-95 models, the resistors are directly beneath the left headlight, behind a rectangular body panel. The resistor allows the fan to operate with more than one speed setting. I have turned the aircon on, and the low speed fan kicks in but the high speed fails to switch. If your fan has stopped working, theres a good chance that the resistor has gone bad and burned the plug that connects to the fan motor.
