Fan only blowing hot/one setting

[danielr637]

Hi everyone

Hope people could advise.

Got into my 04 3.0 this evening and seems only will blow hot air from the vent near the windscreen, whether it’s ok full hot or cold, no adjustment, when toggling through the options on where to put air nothing comes through any other events apart from the windscreen one.

Any help would be appreciated

If your rear screen demister isn’t working it’s likely the car has gone into transport mode as a result of low voltage

ah okay, is there common reasons why the rear demister wouldnt work? I will check and see

Can you adjust fan speed? If so, not transport mode.
This sounds more like a failure of the servo motor that adjusts the directing flaps in the heater assembly, or possibly the switch on the console.
If you hit the switch for max demisting then it only goes to the screen regardless of where you turn the direction knob too.

Hi,

Yeah I can adjust the speed of the fan. Does the switch on the console control both the switch on the far left where the air travels and the one on far right for temperature? as both don't do anything when I toggle them

See if you can swap the switch unit over? But check fuses and codes first.
