I have an 02 Grand Caravan, and every winter, the blower motor resistor goes out and has to be replaced because the fan only works on high.
I replace it, and it'll last about a year and then go out again.
Is the only fix to replace the blower motor? How much would a typical repair shop charge for that? Someone told me that it could be moisture getting
Any tips or suggestions would be appreciated. I can replace the resistor, but I'm not a mechanic, so detailed suggestions would be appreciated. Thanks!
Just a guess, but the blower motor might have a shorted armature winding, and if it stops with that winding in contact with the brushes, the next time you turn on the fan the resistor will see a very low impedance path to ground. Et voila, toasted resistor.
No idea how hard it is to replace the blower on that model...

Are you replacing it with a MOPAR part or aftermarket part? Mileage on the vehicle is?

I get the part from the dealer, so I assume it is a MOPAR OEM part. The van has about 109k miles on it. It started doing this at about 80K and we replaced the part three times now, about once per winter.
