air con, what tempreture
 

when the air con is running and for this question the controls are set on both sides to 16 degrees, what temperature should the air out of the two centre dash vents be?
Interior of car is warm to hot due to sun being on it all day.

4 degC or less

Dependent on outside air temp, most modern A/C systems can reduce the air temp up to 25c. If the outside air temp is above 30c you will struggle to get 4c.

We are lucky here in the UK the air temp rarely gets that high so our A/C systems have a fairly easy life but when it does you soon realise if your A/C system is in need of a service and I don't mean a top up.

tested yesterday after new condenser radiator fitted and re-gassed and it was 7 or 8 degrees..
The outside temperature sensor is not fitted to dash shows -30. not sure f that makes a difference

It was low 20's yesterday so I would have thought you should get it colder than that.

Was the fan cutting in?

It sure does. Why would the aircon freezer system run if it sees an ambient temperature so low? The aircon system operates on temperature differentials one of which is the ambient. Logically, it cools ambient air to a setting that's below ambient.

Connect up the sensor and once it recalibrates to the correct reading, try the aircon again.

Ian,

Did you select 'LO' on the temperature control buttons?

Are you measuring the temperature at the face level vents?

Is your radiator fan running continuously?

Was the system left to evacuate for about 30 minutes before recharging?

I've wondered that ever since I noticed mine running when there was snow on the ground.

Does not the thumbwheel under the clock position affect the temperature from the vents:shrug:
ie, open or closed:}

A valid point to raise Ron and yes it does, but it is fed by air whose temperature is controlled by the rocker switches. This is why these should be set to 'LO' so that there is no heated air being distributed.
