Why is my air con not working on my Smax?

Why is my air con not working on my Smax?

HiMy air con does not work. Engine cooling fan does not come on. Have found a break in pwm wire which I have repaired. I now have 14v on fan unit and 12v on pwm wire at fan unit.

Is the engine cooling fan on Ford Focus working?

If AC is switched off and its a warm day. In traffic. The fan only comes on at 105’C, think it will bring the temp down to about 95’C. With AC on, the max temp I got was roughly 95’C. I suppose that it’s not a problem, but the fan on the Focus never ran, yes, it was working.

Why does the radiator fan not come on when the AC is on?

In order for the AC Condensor to do its job it must stay as cool as it can. As for the engine coolant temp sensor, if the coolant is not hot enough to make the fan come on, then there is no need for the fan yet and there is no problem.

How does the climate control work on a Ford Smax?

At the control panel for the climate control system, PRESS the “OFF” and “FOOTWELL” buttons simultaneously for exactly 2 seconds, then PRESS “AUTO” within 1.5 seconds. The self-diagnosis which then starts lasts a few seconds. An animated display appears in the EATC display during this time.

Why is my Ford’s Max cooling fan not working?

When the fan is connected, the PCM module can see the 12V on the pink wire, so when the fan is disconnected, the 12V disappears from the pink wire and the PCM can detect a fault.

Where is the fan cable on a Ford’s Max?

The wiring loom from the PCM goes through the arch and at about 6 inches in to the engine bay (pretty much under the bottom radiator hose) part of the loom goes up to the top. This bit of the loom is cable tied to the inner wing. This contains the pink control wire which then goes across to the fan controller.
