White Smoke from air vents?

Greetings all - first-time visit to this forum which I have just found via Google.

I have a 2007/8 Freelander2 TD4 - which last week, after about ten minutes of running, suddenly started producing a significant amount of white smoke (apparently not steam) through the dashboard air-con vents. This lasted for five to ten minutes - long enough to return home and call 'assistance'. Needless to say; the fault did not recur subsequently.

The car is now with a main dealer - whose methodology appears to be to leave the car running, to see if the fault recurs. (Which I imagine is pretty unlikely.)

I am certain that this was not some kind of condensation issue - and the only reasonable thing I have come-up with on the web, is the failure of a resistor in the blower motor (non LR) - effectively burning-up - and which of course will not recur. Whether or not the Freelander has such a resistor, I have no idea.

I suspect I may soon get a call from the dealer, saying that nothing is wrong. But before that happens - I wonder if anyone else might have any ideas or suggestions on what this can be.

Many thanks for reading, and for any assistance.

John

Have you got air-con?

yes - in its 'Climate Control' guise

if it was a resistor burning out, it would no longer work on one of the speeds

it's just your air-con, its condensation of warm humid cabin air as cold air blasts from the vents.

The resistor block is green up under the centre console on the drivers side.

As Op Prime said, usually one position on the heater dial goes, it will always work on position 4 [EDIT] as there is no resistor on the circuit.

You can solder in resistors from Halfrauds,much better than the OE type
