Unable to change aircon blower options

[AdrianL]

Hello,
Wondering if anyone else has had this issue...

Aircon blows nice and cold, no problems at all, can change all the settings and everything works fine.

But then after a while, you can hear it blowing but it's almost like it's blowing behind the dash... nothing comes out of the front vents despite being on the coldest setting and manually changing the settings (e.g. face / feet, etc).

Anyone had this issue?

Thought I'd ask first, as trying to take it to Lotus will probably result in me being without the car for several weeks.

Cheers,
Adrian

Seems HVAC need replacement

I had same issue and was replaced

Interesting, thank you. I'm concerned that it seems to work for a while at first, then stops - worried they'll fob me off saying it's working!

Do you know specifically what was replaced?

Hi @AdrianL , did you get this sorted in the end?

I have the same issue. They reloaded the CCM (climate control module) software and it worked for a bit and now it's gone again while driving it home . Will have to call them up and book it back in again.

There has been various posts about HVAC issues resulting from water ingress. Do you know if you have the water proofing fix applied? Possibly the issue.

Certainly sounds like water ingress, which has been common.

I had asked about the resistor failure and rubber seal fix when I had it serviced. I was told that mine wasn't affected (whatever that means) and didn't need anything doing. Then it started acting up after the service in typical fashion.

I'll find out when it goes back in again. Very odd as it did work fine for an hour while driving it back from the dealership tonight. And it's more an issue of the air not coming out the vents now, as the other person described.

At times it works. At times it doesn't.

I took a short video.

I don’t believe there are any cars that “aren’t affected”. You either have the rubber shroud and fuse box seal fitted or you don’t.

Either resistor failure (already had this fixed) or broken actuator buried in the dashboard (fix due in November, the entire thing has to come out..........)
Can you still control the temperature and/or fan speed? If temp is stuck you likely have a resistor failure. If it can be controlled and just the flap position is stuck you have more likely broken flap mix actuator thingies..

It seems to work fine on non-AC after trying it out today.

Can change temperature, fan speed and airflow vents.

But it falls over when I turn the AC on. Then it blows cold air, unless I turn it up to 28deg C and after 10 minutes I can't regulate fan speed or airflow.

The system resets after a minute if I turn AC off. But then I have had the issue where no air comes out, even though I can hear the fan motor spinning - suggesting the airflow flaps aren't working.
