I have a 2003 Dodge Grand Caravan and the rear blower for the air conditioner stopped working except for on the highest setting. From my quick checking it looks like this should also apply to 2001, 2002, 2003, 2004, 2005 Dodge Grand Caravan and Chrysler Town & Country. Here are my instructions on how it fix it yourself:
Pickup the resistor (when the fan is on 4, it bypasses the resistor), so you must replace it. I bought it at the local Dodge dealer — part number 5019189AA. The list price is shown to be $21.20.
Grab yourself a 5/16″ socket and ratchet and get started. It only took me about 10 minutes. This grate pictured below is where the blower motor is located:
Pull this plastic strip straight up, it will pop off. Pull the whole thing off and set it aside.
Then pull the side panel off. I had some trouble getting this off and could only comfortably get the bottom clip off, so I just replaced it by bending the panel back like shown.
This is the blower motor resistor. Remove those two screws with your 5/16 socket. Be careful not to drop them in the nest of wires.
Pull the resistor out and pull back the red tab to unlock the thumb lever and push down on that lever and pull:
This is the old resistor…hmm that goo coming out the side can’t be good. Put in the new resistor (you can handle that). At this point, go test the blower motor to make sure you did it right. Make sure to try both knobs if you can’t get it to work (front and rear).
I pulled this white clip out of the metal and placed it back in the plastic panel. Make sure the one above it is correct, too.
I first put the front flaps back underneath, then popped in the clips in the back.
Make sure that the weatherstrip is over top of the panel.
That should do it! If this helped or you can help make this better, please comment below.
