My car Proton Saga Iswara 1.3L
when i travelling for long distance
at first the air cond is very cold...then when driving about 2-3 hours nonstop
the air cond fan like not working..... the more i drive, the less air blowing out
i only can hear the air cond's engine(is that call engine? ) sound noisy only
but i still can feel the cool.....just no enough blowing out


i already service my air cond and also change the switch for fan and temperature
i also change the temperature sensor already
but still the same.....

this month i need drive to Ipoh for wedding dinner and also fetching some girls
anyone got any idea what happen causing this problem?

thanks for your help ...sorry for my english

u should not put the cold to the maximum coz it will make the compressor frost. u should put abt 80% oni in the meter for coldness. i think u hav been cheated by the person who asked u to change the switch fan n sensors. ur car is alrite bt u didnt realize it. when the compressor is frost, it will oni hav like white smoke comin out bt wil b cold n very less. so put it abt abit higher than half of the cold, let it start n stop automatically. then evrytin should b fine.

yup. put it 80% you can save a lot for long run and less trouble....

i know the aircond guy its ok for max... but that is how they cari makan ..

im having the same problem bro ...i feel ya..
it is troublesome in long journey especially when ur not alone huh?

Yes, ice forming on the evaporator coil will block the airflow, u probably need to adjust the thermostat to a higher temperature, or even open the windows a bit to let in warm air to defrost it faster.

change aircond fan..

dont put the temperature to the max....as i always get scolded by dad...coz i put almost to the coldest zone....try to put half also ok d.....at least got some cold air and wind blowing u and ur galz for ur next travel to ipoh

Try set the temperature lower, I have also put to max but the air-con although not frost but feel like less cold as time goes while driving.

mine is saga year 2005. Aircond become very warm under hot sun when stopping a while (eg: at trafic light, by road side).
but, when start to drive again, aircond become cold.
Only happen during hot sun.
Anybody know solution??

condensor fan getting weak or not spinning d... get it changed... check ur refrigerant pressure as well...

i am facing the same prob. iswara driver here. yeah the white smoke will come out after 1 or 2 hour driving...

"condensor fan getting weak or not spinning d... get it changed... check ur refrigerant pressure as well..."

thanks for advice..cost??

the fan motor shld cost rm1xx..
check refrigerant pressure(masuk gas) about rm40-rm60..

Adding another extra fan in front of condensor made sense?

could improve cooling at slow speed....

If you condenser's fan is in fairly good condition,
you don't need to add another one in front of it.

Will only put more load on the alternator. One fan
is about 80 watts = 80/12 = 7 amps.

The aircon shop usually have used fans, including the
mounting. I changed mine in my former car (an old
Toyota Corolla KE70) for $60 or $70. My aircon man,
Ah Tee, said it was actually a Wira condenser fan.
He even tried to change to another better blade for me,
but it couldn't fit. I remember I when I sold the car a few
months ago, that fan had been going strong for 3 or 4 years.

One should not turn turn down thermostat too cold.

Firstly, frost will form up on the evaporator's pipings,
as the others say.

Secondly, the compressor will be running most of
the time, and thus will shorten its lifepan.

Thirdly, if the compressor is a heavy one, your fuel
comsumption will be high.


Try not to turn your thermostat past half (about 3 o'clock
on your knob) during the daytime. At night, try to set it
to the warmest, about 12 to 1 o'clock.

As for gas, if your compressor uses the older Freon R12,
I think it costs about $30 now. If you need to change the
receiver-drier (or filter) when servicing, that is another
$30 or $40. Plus service charges, it will come to about
$70 to $80.

If your system is using the new R134 (ozone friendly) gas,
I heard that may cost about $80 to refill.


You can take it to my usual aircon man's shop in
Kepong, if you like. He's Ah Tee, 012-303 9547.

Chee Wah Auto Air Con,
996 Jalan 1/32,
6th Mile Jalan Kepong, KL.
Tel : 6250 5711.

It's right at the left turning, just after Maybank, and
followed by three clinics - Polyclinic Liew, Klinik Jinjang,
and Klinik Tan. The last half shop just before the left turn
is a small organic food shop, beside Klink Tan.

His charges are reasonable, but be aware he can be
quite busy at times.

Added on October 16, 2010, 3:50 amThat is more likely due to insufficient gas, or the
compressor is getting old (pistons and seals worn, etc.).

Both will cause insufficient compression at idle speed,
and thus inadequate cooling, and becoming better and
colder at speed, since the compressor will be spinning
faster.

At five years, I think it is more likely due to the former,
since your compressor is probably still in fair condition.

At normal usage, some gas will leak from the system
over time, so that is why we need to refill from time
to time.

Sometimes your system, such as the compressor
inlet/outlet, pipings and evaporator inlet/outlet
may also leak, so you will lose gas sooner.

Any competent aircon man should be able to check
for that.
