Hello Can anyone help me with a problem.I have a 07 Focus and the temperature control has stopped working,only cold air is blowing into the car.There is hot water in the pipes under the bonnet,it's just not getting into the interior.Thanks.

 

Sounds like you have that common blend door problem where the door motor quits working either because of stripped gearing or broken door pieces.
There is a company that makes a good replacement if you are contemplating repairing it yourself.
