    Default No hot air blowing from vents

    Driving back from work this morning, the heaters never worked. Engine temp was all as usual. Fans settings 1-4 still worked fine, just cold air pumping out

    Any idea's anyone?

    Blocked heater matrix? Heat control dial not actually working?

    I had an old Mondeo with a blocked matrix and in the middle of winter it didn't matter where the dial was pointing - it was COLD!!

    Mine did this about 4 weeks ago. Turned out to be a sticking servo motor.

    Can you hear the motor when you turn the temp dial?
    If you take the glove box out, to the right behind the stereo you'll see the blower / air distribution unit. You should then be able to see a red (i think) arm that moves the hot/cold flap. Move the temp dial to see if there is any movement.
