If you have a light switch where you can brightener it or dim it that is a VARIABLE RESISTOR.
yes, a variable resistor
where is the switch resistor on 2003 buick
I wanna use resistor , capacitor and amplifier 7173 for switch alarm circuit. How can i choice resistor and capacitor value because i wanna use 24V DC.
No, they are not the same. A resistor is a current reducer and a relay is essentially a switch (using low voltage to switch high voltage on/off)
Connect it, in series, to a resistor or a dummy load and a switch. And then throw the switch.
If the resistor was bad you would still have high speed. If you have no speeds I would suspect the switch and/or pigtail plug at the switch.
current through the switch become 0.and switch become a high value resistor.

Your truck has both. the resistor is between the switch & blower.thje resistor controls the blower speed
It's in the resistor block, which in the diagrams comes right after the fan control switch
Examine the back of the switch for loose or melted connections. Then examine the resistor for burned spots. In most cases a burned resistor is the result of a failing blower motor. So if a new resistor burns out in a short time, replace the motor also.
