How To Test Cooling Fan Resistor
How To Test Cooling Fan Resistor. The cooling fan resistor is meant to send power to the fans in steps, so that the fans may operate at different speeds. Conversely the high speed turns on at 100 deg c and shuts off at 95 deg c.
On most systems, there is a coolant temperature switch, that turns the fans on and off. Conversely the high speed turns on at 100 deg c and shuts off at 95 deg c. The cooling fan resistor is meant to send power to the fans in steps, so that the fans may operate at different speeds.
On Most Systems, There Is A Coolant Temperature Switch, That Turns The Fans On And Off.
Chrysler minivans (late 1980s and early 1990s). The cooling fan should cut in automatically and the temperature gauge drop back to. An attempt to measure a resistor that is still connected to the circuit can yield an incorrect calculation, as part of the circuit might also be measured.
It Can Be Replaced, Rather Than Having To Buy A Whole New Resistor.
Next connect the jumper between m2 30 and v2, the passenger fan should run at low speed. Not likely necessary, but that's one solution. In the case of this 2006 gransport, the low speed turns on at 95 deg c and shuts off at 90 deg c.
Place The Black Probe On The White Wire.
These use a solid state relay for the cooling fans, and the relays tend to overheat and fail. Examining the fuses with a multimeter. The problem here is the cooling fan circuit uses a radio.
I Know This Is One Of Those Topics That Has Been Beat To Death With A Stick (I Read Through Every Fan Related Post).
Some vehicles with cooling fan problems. How to check your car's cooling fan set the car heater to cold. Once the blower motor resistor fuse is located, the next step is to test if it's working properly.
Run The Car Until The Engine Reaches Normal Temperature.
The radiator fan on these cars has two separate speeds they can run at, low and high. It does not matter which end of the resistor is disconnected. Every time you fiddle with the fan speed of your car’s air conditioning or heating system, you change the current that flows through the blower motor resistor on the way to the blower motor.
