Aircon - Warm after long run?

[OTF-39]

Hi all,

I have a question here regarding car aircon.

What is most likely the root cause if the air con of a car become warm after a long run ? (eg, after driving it for 2 hours at highway)

Whenever the car is start, air con was cold and okay.

Thanks

Izit true tat by 2010 there will be no R-12 gas and only R-134a gas? Then wat to do with older model car air conds?

the problem is call icing up.

you see, when we demand maximum cooling power, after some time there will be ice build up at the evaporator @ cooling coil. the problem is, compressor does not cut off even though its already cold.

check entire aircond system. clean cooling coil if dirty because dust deposit makes it easier to become ice and block blown air from the blower.

temporary measure to counter the prob - after half hour (or when cabin is cool), reduce the themostat bit by bit until the you are most comfortable. if icing up still occurs, switch off air cond. let blower runs alone and it will melt the ice.

this problem happened to my 20 yrs old mitsubishi super touring several years back.

i think it's a bit earlier.... r-134a is more enviromental friendly than the r-12. So for older model have to change the tev/coil i think...coz r-12 tev/coil could not use r-134a gas.....if i'm not mistaken
