It is located just left (towards the driver side) of the blower motor base. The motor base is on the passenger side under the glove box and is round in shape. Disconnect the wire connector. Remove the two screws that hold the blower resistor into the blower assembly. You may need a short phillips head screwdriver to do this. A standard length screwdriver may be too long and interfere with the sloping foot well at this point.

Where is the heater blower resistor located?


The resistor pack wires are usually attached to the same wires as the blower motor. I strongly recommend replacing the blower motor at the same time if possible. It's the blower motor that is usually the reason for the resistor pack going out. So if you put just the resistor pack in, and shortly after, it goes out again then you'll know the blower motor needs to be replaced.
I hope this info helps!~subyguru~

Front blower only works on high, what part do i


There are two things I can think of that may be causing your problem. First the blower switch in the dash may be bad if you do not have an electronically controlled blower, if you do it could be the control unit itself, but usually they stop working alltogether. The other part which may be bad is the resistor pack on your blower motor.

If your blower has four speeds on it like most blowers these days then this resistor pack will have four resitors mounted on it. They look like coiled wires. These resistors vary the voltage coming from the blower switch so you have different blower speeds. Kinda acts like a filter dropping the voltage for the lowest blower speeds incrementally.

If you want to diagnose this yourself it shouldn't be too hard. You will need a 12 volt test light or a multimeter to test for voltage. The blower motor should be located unther the hood of your vehicle on the passenger side against the firewall. It looks like a round black box with wires going to it. Where the wires connect to it the resistor pack is on the other end of the connector inside the motor housing. There are usually two screws or bolts holding it into the housing. If you take these bolts out it should come right out. You can visually inspect it and you may notice some charring on the circuit board where the resistors are.

I would measure power with you test light from the connector before it goes into the resistor pack. If you are receiving power at all blower settings then your blower switch is likely good since this feeds the signal to the blower motor.

You can then use a multimeter to ohm out the resitors on the resistor pack. If any of them show to be open you have a bad resitor coil there. You have two options at this point, you can unsolder the old resitors that are bad and try and replace them with comparable resitors from radio shack. Or you can go to rockauto.com and order a new resitor pack. They run about $16.00-$20.00.

Blower motor stuck on high! 2001 town &country 3.8 lxi. unpluged blower control module and blower motor still stuck on high. any ideas? thanks ED


your blower resister is bad and you need to replace it.......heres how,The glove box can be lowered all the way out of the way just by pulling in the sides so the rubber stoppers come out toward you. The sides bend easily to allow that.

The glove box being out reveals the resistor in the heating duct right in front of you. Just remove the two sets of wires and two bolts (10mm socket, I think) and the resistor pack slides right out. Then bolt in the new one an plug the wires back in (they only fit in one way). Fold the glove box back up and press the stops in to get them back in place and you are done.

The resistor pack only cost $12 and change at my dealer. It is part number 1-04885583AB which was a replacement for the same number with AA at the end, so I’m guessing they had a lot of trouble with the AAs and so made a better AB.

Last Winter my heater blower fan worked only on High. I changed the front heater/AC blower resistor pack and was surprised at how easy it is, but I had to figure it out for myself since my Dealer's parts guy was no help as to where the part lived and my Haynes manual was just plain wrong. This was on a 2001 T+C. I'd be very surprised if the 2001 Caravan was any different. Don't know what other year vans would be the same. I do know some earlier generations had this resistor under the hood and Haynes had is with the blower sort of behind the instrument cluster.

Where is the front fan resistor unit?


Look under the van,on the drivers side near the radiator,it should be in that area.Follow the wires from the fans,they should go right to the module.This is for the cooling fans for the radiator.For the resister module for the blower motor look near the blower motor in the blower box.It is near the blower fan.It can be under hood,but it will be mounted with two screws.Remove the two screws,but you need to remove the wire plug in first.Pull it out .It goes inside of the blower box.If you replace this module,replace the blower motor also,because the blower motor is what causes the resistor to burn out.Did you check voltage at fuse with key on?If you did not check the fuse with key on,you got a false reading.If you checked the fuse with key on,look for a bad ignition switch,or a fusible link burned into coming off a pos. terminal post where the battery cable goes to under the battery.If the blower will not work at all even on high blower,the resister most likely not the resistor.The blower motor relay is most likely the problem.

Your heater blower fan unit is in need of replacement.
It's a difficult job so take it to a service center.

I HAVE AN 06 H3 HUMMER the heater was blowing fine when I shut the car off ok, when I got back in and started it the heaters blower stopped. I have checked all fuses and relays and they are fine I even...


check the blower speed control, it most likely burned out, also jump battery power direct to the blower and see if it runs, if it does the speed control is defective, if it doesn't the blower motor is toast.
