2005 Focus. I'm getting no hot air from the heater, just cold air. (I'm a newbie, so apologies in advance if I'm mis-posting.)
I've removed the stereo, and I can see that the mechanical heater cable isn't retracting when the temperature knob is turned to hot. I assume there should be some kind of spring mechanism at the other end of the cable which pulls the cable back to open a heater control valve.
So my first (very basic) question is: Where would I find the other end of this cable (where the spring mechanism is)? Is it easily accessible? I read somewhere that I should remove the lower panel in the driver's/passenger's foot-well, but I've done that and cant see anything that looks relevant.
And the next question: What are the likely causes? Kinked cable, broken cable, seized valve? How easy is it to replace a cable?
In case, I haven't explained clearly - I'm attaching a photo showing the end of the cable that I'm talking about. In the photo, it's disconnected from the temperature knob, and you should be able to see that it isn't retracting back into its sleeve.
Thanks in advance for any suggestions.
