Hi all, just wanna ask if anyone face a/c issue. While driving, a/c suddenly blow warm air or outside temp air with stale smell.

Tried many things like change battery, on off a/c, go to workshop, all cannot solve. Workshop tested and straightaway said compressor issue.

However when i tried to turn the blow mode all the way to windshield defrost back to face level blow several times, then off and on the a/c again, things get solved, hopefully for good.

Suspected the system confused with heater mode and a/c. Any other solution to this?

Workshop said gas is enough.

When the problem happen, it happen for months. While stationary, cannot hear compressor kick in. But when a/c working randomly, air is very cold.

This morning, after cold start the car and drive to a traffic light near my house, the a/c is working while stationary. But everytime it kicks in, my battery voltage go down to 13.2 and then go back up to 14.3. I use the usb charger with voltage meter.

After a long drive to work, while in traffic jam, the voltage did not go down when compressor kicks in.

Your car is 2.0p i assume. Mine is 1.8e with manual a/c.

My far right dial is on, meaning circulation is on and no smell of lorry exhaust. I guess my issue is a bit different from yours.

But thanks anyway for the clarificafion.

I first thought it was battery issue. But change battery recently and the issue just gone from bad to worse, until i somehow learn to swap defrost mode to face blower multiple time to fix the issue momentarily.

Maybe sensor issue as you explained. As air is super cold when no issue. But turn to room temp randomly.

1.8e with manual a/c.

So far still happening every day. But i will switch to defrost and back forth few times until i can feel the cold air to solve the issue temporarily.

Maxxoil full syn. Last time using syntium got engine knocking. Now very rare after almost 50k running this brand.

Do you have the address to the exact workshop?

Kena 450 for one side last month. Got wong wong wong sound, after change, like new car so quiet.

JTech Autoserve in front on menara PGRM. Cannot remember how much if change oil only.

I thought that issue has a recall few years ago? Go to any proton authorized service centre can change FOC. Mine got this issue happened to me at night, quite scary.

Did mine there too...now no more overheat and whining sound issue. So far no need to install cvt cooler.

I tried syntium years ago with my 1.8, a lot of knocking sound when paired with any RON quality from any gas station brand.

Somehow, i found Maxxoil 0w-20 paired with ron95 petronas give the best balance of power and fc. It's about rm200 incl. labour and performance would maintain until 7,000km+ when you can start to feel low speed sluggishness.
