Is the air con fed just through the two dash front vents or does it come from the screen and foot vents as well.

Reason I ask it the screen vent just wont get cool. Also does the flap setting in the computer affect the
coll air temp in any way. My air con is just not that cool.

AFAIK, the cold air comes through the dash vents only, in turn, the hot air doesn't come through the dash vents, odd and overly complicated set up if you ask me. (as I found out when mine failed!)

I think you get cold air from the inner footwell vents too. Should be cold enough - I suggest closing the screen vents.

Advantage of aircon is a refridgerated glovebox. Perfect for cans of drink or bars of chocolate in this weather.

mine's not all that either but I agree, the cold glovebox is genius, well if it was intentional!

Methinks it was not intentional, but you do pay for that from other manufacturers.

Now for them to invent an accidental cupholder ...

My A/C kept the inside even with it at 41c outside. The cold air only comes from the middle vents but they do the job.

When I first had it I thought it wasn't working very well but it seems it does a better job when the car is moving.

I'd get yours checked, especially if you haven't been running it for at least 15 mins every month.

I have a similar problem. My car is currently in at DM for some work, one of the things I have asked is for the air-con to be checked out as I don't believe it is working properly.

I'm not sure what to expect from the air-con in the T350. I've got used to the air-con (climate control) in the SEAT Leon and I knew it wouldn't be as effective as this but I wasn't expecting it to be this bad!

The air-con seems to do an OK job when travelling at speed (say 50mph+) when it will blow out cold air (still not that cold). The moment you slow down or stop at a junction / traffic etc. it becomes next to useless with the air blowing from the 'cold air' vents becoming hotter then the outside air temp (no colder than when you turn the air-con off and have the fans set to cold, hotter than outside temp I'm guessing due to the heat from the engine).

On top of this when it is very hot and you have the air-con on it is hard not to stall when pulling away, you have to use a lot more throttle than normal to pull away! I also have experienced a squealing noise like a belt slipping when accelerating hard with the air-con on while it is hot.

The car is an early T350 (built October 2002, registered January 2003) with the air-con being an optional extra at that time. I've only had the car for a few weeks so I don't know what it was like new.

Any help or suggestions would be much appreciated.

Nick,

I'm waiting for a new a/c compressor to be fitted. Before that it was the ECU making the a/c run all the time. Maybe I'll have an a/c unit that works for the summer!

You are right, the a/c did get better with speed so maybe you need to have the compressor looked at. The air movement at speed may be acting as a makeshift cooler! These engines generate too much localised heat me thinks.

When you select the a/c, you should hear the compressor kick in. I found it wasn't all the time and I only heard the a/c kick in at high revs or when the engine was cold.

Paul

PS if you go to the computer's main menu and select one of the blank menus (not sure which as I'm 800 miles from my car and I’m not sure why they're blank!) you get a menu which shows all the temp and ventilation values.

I've also found having the aircon on has quite an effect on pulling away, definetly need a few more revs.

I was using the aircon on Sunday but to be honest I didn't really notice a lot of difference with it on or off in slow speed traffic.

I just took it to be that the aircon isn't that effective.

The aircon should be reasonably chilly. I'd get it looked at if you are bothered, might just need recharging (mabye you don't care, some people don't seem to want/need it).

I was told that the aircon only works while the car is moving, i.e. something somewhere requires a flow of air over it.

My car is in having the aircon repaired right now. Apparently the dash ECU was keeping the compressor on all of the time which over-pressurised the system and caused it to trip out.

It works when not moving in mine.

My dash ECU went wrong the other week - the aircon stayed on permanently too. I'm glad it was on permanently than off permanently as we were in the South of France at the time. Seems to be a common fault.

I've had another fault which actually hasn't happened for a while but did happen a couple of times just after I got the car (I picked the car up in nasty weather, but come to think of it I think the air-con was still pretty cold when stationary then!).

With the car stationary for a long period with the air-con on the car would come up with an air-con fault on the dash and would start blowing super heated air out of all the vents (including the cold ones). I had read somewhere that this was quite a common error and after a reset of the blowers and the air-con I think it almost always sorted itself out. If not an ignition cycle would solve it.

Does this sound common?

The cold glovebox is good until you have the aircon on for a while and it fills the glovebox with condensation. Not great when you’ve got anything non-waterproof in there!

Mine also chills the passenger's window/door switches to the extent that they drip with condensation and the radio so much that CD’s start to skip and come out soaking wet and very cold!

I noticed the one thing that does get cold is the window / door switches. I never noticed the glove box getting cool, I will have to check that out! I haven't noticed any condensation as yet. It sounds like the air just flows through the hollow dash with no insulating at all!

My glovebox and passenger buttons get cold too - great for cooling drinks on a long trip, but a bit odd to have the button panel 'icing' over. I normally just turn the aircon off for a few minutes and let it 'warm up'.

My Tam is a 2005 model and produces buckets of cold air through the dash and footwell vents. There is no recirc. facility so it is always pulling in new & warmer air from outside. Good practice is to run all AC for a few minutes every week I am told.

Car was in at Dream Machines last week, got it back Friday evening. Had the system re-gassed and all is now good! Obviously not really a touch on my SEAT Leon Cupra R air-con but it is now actually cold, even when stopped! I noticed the cold glovebox as well, boy does it get cold in there! The small crack I have in the glovebox makes it even colder as it lets air into the glovebox! Should be good to store drinks on those long European trips. I did notice the condensation though on my TVR manual, maybe I'll move that.

I believe there will be a heat exchanger that looks like a small radiator somewhere. There would (should!) be a flow of air over this when moving, so that may explain the greater temperature drop at that time.

However, it shouldn't give up totally when you come to a stop, unless the heat soak from elsewhere is that great.
