Question about 2002 Chrysler Town & Country

Blower motor just stopped working in my 02 Town & Country

Hello my blower reved up to high speed then completely stopped working.  I have already changed the radiator/AC fan and the associated fuse.  I believe these 2 to be unreleated but stranger things have happened.   Looks like a lot of post about resistor.  Any help would be great.  Thanks in advance.  Zac

    here is a curve ball took out the blower motor s**ts and giggles jumpered direct to my battery and works great????  I checked voltage to fan plug before removing and had 11.87v with fan switch in high speed????  I didn't check any other speeds b/c thought it was ok.   With the resistor bypassed in high what would cause the fan to not work.  Thanks Zac

    Thanks that clears up a little, no burnt parts on resistor.  Still baffled by the motor working when I went straight to 12v battery terminals but not at all when plugged into the resistor.  And the resistor passing power through it at top speed(bypassed) but not powering up the fan makes no sense to me.  I ordered the res. and the fan, won't be here until wed.  Always something  Thanks Again Zac

Chances are it is the resistor. I had the same problem with my 97. Then my blower motor blew. Take the resistor out, and check for burnt, or corroded connections. If found replace the resistor. They blow when the blower motor wears. It starts to draw too much power through it to operate it. And burns out the connections. So I would advise replacing the motor as well.

    The resistor does not actuate in high or low speeds. It only actuates in the mid range. The motor will work on high, and low, if the resistor is shot, not in the mid range speeds. Like I said, pull the resistor, and check for burnt connections. If they are, replace it, and the motor. As the motor has burned out the resistor. Change both.

    It sounds stupid, but on high, and low speeds, the resistor is bypassed. The resistor is only required to control the power to the motor in the mid range speeds. I have no idea why they set it up that way, but it's the way of the world these days. I had a broken wire to my fuel tank, and it took out my entire cluster. No Speedo, Odometre, or anything. Used to be it would affect one thing in the system. Electrical problems are a nightmare these days.

HI Zac the resistor shoud be bypassed in the high setting, If it is not working at all I would suspect the blower motor. If you have a volt meter you can check the power to the blower, should read about 12 volts with the switch in high position.

Ok so i took my 97 TnC to the mechanic he explained a similar thing to what Zac was saying. though he didn't say anything about the resistor. so what your saying is replace the resistor and this should fix the issue?

Blower motor is bad. Resistor controls speed. Motor is so worn out that it will only turn when set on high. Best to replace it before it burns out something else due to the high current draw.

2001 Chrysler Town & Country air conditioner/heater blows on high only. We have replaced the front blower relay and it still doesn't work. The back blower is the same.


THE REASON THE BLOWER ONLY WORKA ON HIGH IS BECAUSE OF SOMETHING CALLED THE BLOWER MOTOR RESISTOR. THIS IS A BLOCK WITH ABOUT THREE DIFFERENT RESISTORS ON IT WHICH CONTROL THE AMOUNT OF VOLTAGE THAT REACHES THE BLOWER MOTOR THUS GIVING YOU YOUR DIFFERENT SPEEDS.
THIS BLOCK IS USUALLY LOACATED BEHIND THE GLOVE BOX AND IS BOLTED TO THE HEATER HOUSING.

2002 town & country blower motor will not


In order to achieve different speeds for the fan motor, there is a bank of resistors that reduce the voltage depending on what speed is selected. This is basicaly the same design for all cars on the road. The fail mode causes the full voltage to bypass the resistor bank so the fan runs at high speed (maybe even higher than your normal high setting). On most newer vehicles, including your '02 T&C, to help keep the resistors cool, they are mounted to a heatsink and then that assembly is mounted in a hole in the A/C ductwork just below or behind the glovebox. My '02 T&C has the 3 zone auto temp control and it had a fancier resistor block, but the function is the same. You should be able to get the cheaper one for <$25 at a parts store.

you need a blower resistor maybe a blower motor also but the resistor is for speeds and it usually goes when the blower motor starts to draw too much power the resistor is outside under the cowl on the passanger side you may need a connector pigtail also the dealer will have what you need

Front climate control blower only works on high speed.


Replace your blower motor resistor
Resistor located under dash on passenger side in screwed into blower housing. May be able to be repaired. Requires soldering a small piece of "unmelted solder" across where the old fusible link was. look carefully at resistor. Or else just replace. Buy new. Junkyard resistor likely to be as bad as yours.
