  • HVAC problem-help

    in my 06 sentra, when setting the heat to come out on the full feet setting a little air blows out of where the defogger air comes out from and when setting it to the dash board vents the driver side middle vent blows out very little air, all other dashboard vents are working.

    Have you checked the blower?
    Me and my father Just replaced a HVAC blower in a 2001 Chevy Malibu.
    Check:
    Fuse
    Relay
    HVAC motor

    If it's not a fuse or relay, it is likely the motor. Disconnect the motor, and check for voltage with a multimeter. The voltage should be 11-13.5 volts.
