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 where it shouldn't (the blower motor wiring?) and causing the problem. Could this be true, and if so, how can I check that and seal it up?
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!
