I have hit a dead end. My AC had inconsistent flow for a few days then stopped blowing altogether. The heater does not blow either. I have replace all the fuses, the blower motor and the 12v battery with no success. When I turn on the fan it moves about 1/4 inch and that’s it. Any idea on where to go next? thanks
Head to a junk yard and pull a fan... Of course maybe there's a fan relay that's failed? If it's a capacitor I would think that's probably built into fan, but have never taken one apart. Everything already vacumed out and cleaned?
