Blower motor resistor?

I cannot find the resistor to check it. Would you know where it is? With the plug on the blower motor having power, is it a grounding circuit that runs thru the switch and resistor?

As I stated before, I have already checked the motor and it runs fine. I am getting full voltage at the blower motor plug regardless of the position of the switch. At the blower motor plug there is a green wire and a blue striped wire. The green wire has 12+ volts all the time. When checking with a volt meter across the 2 wires (with the plug disconnected) I get no voltage. With the plug attached to the motor, I grounded the blue striped wire and the motor ran fine. As I stated before, could this be a grounding circuit where the resistor/switch act as a variable ground? Would that mean that the resistor is somewhere between the motor and the switch on the ground side of the circuit? I still have no idea where the resistor would be located so that I could check it to see if it needs replacing.

Joe, Thanks for all of your help. I finally found the resistor, replaced it and now everything is working fine. It's the somewhat simple things in life that make you happy. Having heat again is one of those simple things. Your persistence and expertise is unparalleled and beats going to a repair station just to pay a lot of money to find a simple solution.

The blower motor resistor wiring pigtail melted onto the resistor. I purchased a repair kit for the pigtail. It was a universal repair kit and has 3 wire sets. I used the set that appeared to be the same guage wire as the original wires.
Now the blower fan blows low on the low(1)and low/med(2) setting and medium on the med/high(3) and high(4) setting.

I plan on purchasing another resistor to see if that is the problem but also would like your opinion.

I replaced the wiring and resistor because they were melted together. I am having these problems with a new resistor and wiring.

Hi my heater fan did not work on the low setting, but worked on the high setting, then didnt work at all.
I was told it could be the heater fan resiister Do you know where it is located?

My heater only works on high spped, I was told I needed a new resistor, I am having trouble locating the spot in the vehicle where the resistor is located

The heater resistor card is located right under the glove box lower front left right over your left foot if you sit in the passenger seat you should see a 4 wire plugged into it. You need to remove 2 screws with a 1/4inch socket and you will have your resistor.

I cant find that little resistor coil (looks like a reastat) that is supposed to be on heater box under dash. Heater fan works on bench, relay good, fuses good, but heater fan works when it wants to.

I'm having a short problem in the wiring harness at the plug it's burning the plug out in already replaced the resistor and put a pig tail on to replace the burnt out plug because the first time it had looked like a wire had been pulled out somehow and it shorted but now it's done the same thing is there any way if yall have it I can get a wiring digram or yall can tell me what the dark blue wire with a yellow stripe leads to so I can figure out what is causing this. No fuses have been blown so I don't know what could be causing this.

It the one inside the cab directly under the glove box area
