    You disconnect the negative terminal of the 12v battery that is in the rear seats, leave it like that for a few minutes and the problem will solve, that's what i do with mine.

    Still having the same issue to this day. Used heat, then moved the knob back to cold, but only hot air came out, so i had to disconnect the 12v battery.
