My blower motor steadily slowed over the last year & now doesn't work at all. I replaced the brushes, checked it out with a direct 12V jumper to the battery, etc. reilnstalled it, and noticed it still didn't turn unless it had a full 12V applied. It gets pretty warm with the humidity & all down here, & I sure would love to have my A/C or even the vent blowing some air (fine at road speeds >30mph, nothing at stops). Any suggestions?
