Aircon issues

[Glenn Parker]

Hi All Happy New Year, I have a VE 2007 Calais, the Air con on auto cuts out restarts , did the same on manaul mode. It's cold when it's running tho in the end it stays on, just when it's turned on at the start.
Any ideas?

Might be the evaporator icing up.
Was a problem in early VE's, needing the temp probe repositioned.

Here’s a doc which outlines VE aircon diagnostic hints.

From the above doc, it says:

ECC / MCC Vehicle - Evaporator Freezing Up. A/C temperature very cold for a short time then increase in vent temperature with a decrease in blower fan speed. Faulty evaporator temperature sensor or sensor requires service modification to relocate the sensor tip 15mm further to pick up the temperature in a different location or low refrigerant charge, possibly frosting the suction tube.​

​

So if it is indeed the sensor location at fault, here is a doc that defines how to relocate it

Thanks Guys will give that a go

It’s fairly easy to do.
There could certainly be other things at play.

Do let us all know how it turns out since it completes the thread and becomes more useful to others who may find it in a search...

Hi Guys have given that a go, plenty of hit days in Mildura, but cutting out but not as for long.
Have cleaned the condenser, was going to recharge the system , anyone know the gas charge please.

Have it checked and re-gassed, if necessary, by a licensed air con technician.
