Cold air but not much of it

[fatjon]

When I first start using the car I get loads of lovely cold air from the vents. After 20 minutes or so I get only the faintest breeze. Aircon still working fine as the air is still really chiily, just very little of it. Anyone have any tips on where to start looking?

I can still control the flow from zero to not much with the twiddler btw.

Is the aircon actually too cold ? Water vapour sometimes freezes on the matrix in this situation and reduces the airflow. I think we used to set the air temp thermostat to about 5degC to avoid the freezing issue.

Will check that. There's a stat somewhere I know as I saw it on the wiring diagram. Any idea where it is?

[spitfire4v8]

should be either mounted through the panel which is above the driver's knees, or cable tied to the roll bar tube near the driver's top door hinge.

Not enough flow is strange, when you find out please tell us as mst of the time the aim is to try to reduce the flow. The air comes inthrough the vent under the drivers side indicator. Possibly the wing is full of leaves and when they dry out they blow inot the fan ? I dont know how to get at the cold fan though.

Sorted, thanks all. I turned down (up?) the aircon stat and managed to get to work today with the aircon still working without freezing up the evaporator. Still plenty cold enough too.

Do you remember which way you turned it? I would like to make mine a smidge colder

[fatjon]

Truth be told I didn't turn it. As my username suggests getting upside down in the drivers footwell is a gravitational challenge too far for me, indeed even getting in/out the right way up is accompanied with huffs, puffs and copious vulgar cussing. My son did it for me as he's a 15 year old racing snake. I'll ask him later and update you.

I was starting to wonder, as the more recent fatjon doesn't sound like the fatjon I remember from five years ago. Perhaps your son has taken over your PH account as well.

I've spent five years driving a desk or in hotels with nothing better to do than eat and drink. I also lost my brother who used to work with me on all our projects, which was a big blow.
The doctor has recently pointed out to me that I have become "rather portly" and should buy either a push bike or a funeral plan. I'm looking on Ebay now for a bike as the least worst option. Those hybrid ones which you don't have to pedal much look quite nice, but I don't think that was quite what he had in mind.

The Cerbera is a least giving me more exercise than my lollopy truck, both driving it and getting in and out of it.

Yes, this does sound like an ac thermostat issue. Do you get a puddle of water under the car when youv'e parked up? Not sure where the condensate water drains out but it must go somewhere? Usually on the floor with most cars. I'm guessing you get a large puddle under the car shortly after you have parked up? When this happens.
