Iwant to replace the heater blower fan resistor, cannot locate it, I have looked under hood and in dash, nothing looks like the resistor
SOURCE: Heater fan only works on high speed 4.
sounds like the switch is bad. Test the power coming in to the connector and use jumpers to get the fan to operate at all 4 speeds. if it works then it the switch.
SOURCE: i am looking to locate heater fan resistor plug
The blower motor resistor is in the blower itself.
Here are some pictures to help you locate it. These are taken looking under the glove box
The blower motor resistor is to the left of the pigtail shown in the picture. Check the end of that wiring harness also, it could be damaged as well

It should be located on the blower motor housing under the right side of the dash, it will have wiring connector and 2 screws holding it in.
HEATER BLOWER MOTOR
Its
faulty blower motor resistor. The low and medium speed on blower motor is
controlled by resistor and its actual speed is high. So because resistor is not
working, blower motors actual speed which is high is working.
It
can be faulty blower motor or faulty blower motor resistor. Get the blower
motor inspected. If it's faulty it has to be replaced.
