Aircon Issue .... And Its Not A Leak.

[Ogben Schmutzel]

Hello All,

 

This is on a 2002 Alhambra SE with Climate Control.

 

When I have been on a longish run (seems to be 90 mins / 70 miles or so) the aircon stops cooling properly.

 

Engine cold (or after a run leave the engine to cool down - hour or so) and it cools fine.

 

Sounds more like a sensor or something but haven't got a clue really.

 

Any ideas.

 

Cheers.

Oggy.

You could check the drain for the air con - it might be blocked - it's (assuming it's not a dual system) on the bulkhead behind the engine - a sort of rubber pipe affair. If it's blocked it might make the evaporator freeze up. (or not!)

Do you still get normal airflow? Does the compressor clutch click in (noticable "click" from the front of the engine when you turn the system on / off)? Does the high pressure AC pipe at the front of the engine feel hot?

 

Might be low on gas - a regas would be a good start.

Hi Both,

 

Thanks for the suggestions.

 

Pretty sure the drain is ok cos I still get the water under the car after a run.

 

Not sure that I have ever have noticed that cluck you mention. Airflow is still normal though. I reckon you are right that a regas might be the place to start.

 

Regards.

Oggy.
