So. I was out in the old girl over the weekend, drove up to kings lynn and back to London and she was a dream to drive (other than the shimmy I've covered in another post but I just stayed at 68 mph and she was as smooth as anything.)

Anywho, it was quite warm on Sunday and I had the air con on (I usually alway have it running) but I noticed nothing coming out of the blowers, even if I pressed the max button and / or selected the blowers only. Even when I turned up the fans to full, the center dial to full blue and messed with the recirculation thingymawotsit.

The blower vents were freezing but there wasn't any air coming through anything. Eventually I turned off the AC and low and behold air started coming through the vents again (it was bloody cold too but clearly 'warmed up' a little over time. I was then able to switch the AC on and it worked fine.

So my question is, do they freeze up at all? That's the only reason I can think of as to why there wouldn't be any throughput even though it felt freezing at the vent.

She's an 03 l322 4.4 petrol.

Thanks in advance.

Would only freeze if the sensor on the matrix is faulty.

Thank you Datatek, I've got an allcomms, would I be able to see if it was faulty with that at all please?

I would assume so, but never tried it on an L322.

I can put the aircon on and have cold air through the vents but no fan even on full speed or max cold. I suspect is the resistor that has gave up.
