SAAB 9000 1995 ACC Keeps Cutting out When Hot

SAAB 9000 1995 ACC so always on air con - works from cold but cuts out when in jams, hot running. Recently gassed up by me to see if that helped, it didn't. Garage also puzzled. I got as far as realisuing the compressor clutch is not getting power when the car is hot, the fault condition. Seems to come back on when it gets a run to cool the engine/condenser.

When the problem occurs both pipes to and from the evaporator are as hot as the thin delivery pipe usually is when the return is cold

Compressor seems good when it works, gets me cool when its 90 outside , as it is right now. Have changed relay. Ideas please?

Thanks, Brian Catt

You may need some aircon cleaning specially the evaporator, replace the dryer, ur thermo stat might not be working properly, have a leak test then get some freon charge

My Renault logan only blow cold air


So the AC is working, but when you select hot air, it doesn't work? Does cold air come out when you select hot air, or does no air come out? Please provide as many details as you can. What year is the car?

Perhaps the dial to select hot or cold air is not working. Does the dial feel the same as it always has, or has there been a change recently?

Is the engine warm when you try to select hot air? If the car hasn't been running a while you won't get hot air.

Hi, The air con in my 2003 Audi A6 1.9 tdi 130 is blowing warm air the air con rad is fully gassed and all fuses are ok . Thanks in advance for any advice on how to fix


The only other thing then would be if the compressor is turning, engaging, and the cooling fan working properly. You should either be able to see the compressor clutch engage, as the switch is energized, or at least hear it click loudly when the switch is energized. If it is not, then there are sensors for the low pressure/high pressure line to tell the compressor when to function, that also have to be checked.

As the engine runs with the compressor turning, one line should be hot/warm, the othe,r (larger diameter hose) should be cool/cold, if the system is working properly.

If the compressor is turning when you have the A/C turned on, then see if the cooling fan is running as well. It must run to remove the heat and cause the process to function properly.

Good luck!

I have a 2004 lancer . My air con works on cold, but than in an instant pumps hot air. I have had it re gassed and had the relay switch changed. What more can I do


it sounds like the ac compressor is on the fritz, you will probably have to get a new one then have the system vacuumed out completely and the recharged and oiled. it could also have a leak in the line some were.

A/C does not blow cold air.


Hi. It will need to be re-gassed at ur local air con place but b4 u take it there make sure the compressor is working when u turn ur air con on. If the clutch on the compressor does not engage its a sure sign it is out of gas.

Audi A3 Air Con Cut out


Happened to me too, when the ECO light comes on automaticly (and it only blows hot air) it means it's simply broke.

I don't know the exact production date of your car, but there is/was an airco-related dealer recall for some cars, so just contact your dealer and have it fixed, but don't forget to mention the recall (it might save you a lot of money when your warranty has already expired).
