Replacing Blower Motor Resistor

Video on youtube , maybe . Why doesn't work ? Not at any speed ? Does the vehicle have manual or automatic climate control (HVAC) - heating ,ventilation , A/C . Could be blower motor resistor or blower motor control processor , depending on the system .

Hello! it's my job to make things as easy for the customer as possible...Therefore I must ask why you want to replace the heater switch? Is it because you have lost one or two of the switch speeds? Your vehicle is noted for loss of the Blower Motor Resistor...
Changing the Heater switch means removal of the Climate Control Assembly which is not the easiest of jobs...I've included the process...But are you sure the blower resistor is OK? If you have lost 1,2, or all blower motor speeds it's more than likely the Resistor pack. And a lot easier to change...

Chrysler vehicles are notorious for the blower motor resistor going out. If your Town & Country has automatic climate control use a SMP RU399, else use an SMP RU362 for the front resistor and a SMP RU490 for the rear. They are generally located on top of the blower motor/wheel assemblies.

Automatic or manual climate control ? Looking at a wiring diagram an checking power an grounds an current draw is the correct way to test electrical circuits ,not guessing an replacing parts .
Why ???? High resistance problem probably . Volage drop testing the circuit. Your's has blower motor resistor or blower motor controller . module ?

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.

Yes its the blower motor resistor.

More then likley theres some trash or something in it, or possibly the motor itself is on it's way out. There not that bad to pull out of that body car, just pull it out and see what you can see.

The blower motor is under the glove compartment

You can replace the resistor on your own. Please find a detailed diagram which would guide you to do it.
