It could be a number of things but the favourite is the dcc valve.

Maybe the best way is to plug in a diagnostic kit to see what codes are displayed.

I had recently had a similar problem,i changed the dcc valve,regassed the aircon,changed the display,but now have a P1462 fault.

Open circuit which i have as yet not been able to fix.

If you can invest in a diagnostic reader as i have found in the long run can save money when other faults rear their head.

Hi Andy,

I might be able to help as I had the same problem.

There is an electrical switch block situated inside the front offside wheel arch. It can be accessed by carefully pulling back the housing in front of the wheel arch below the bumper (it's difficult to describe, I'm afraid).

Anyway, the wires, and even the switch block becomes very corroded over time and the bare wires start to short out. Hence the hot air blowing all the time.

The affected wires will need replacing as will the shrink wrap.

Sorry I can't describe it more accurately but once mine was fixed, the heater went back to normal.

All the best,

Nick
