Hi all Sifus,

I am planning to get a Hyundai Sonata 2011 from a local car dealer. After spending a day viewing all those cars, I found something in common.

Air Conditioning problem.

It only blows up hot air and no cold air at all. All dealers are telling me that the car hasn't been driven for the past 1 month and probably the air cond gas needs some refilling.

NONE of these Sonata is giving out cold air (I probably viewed about 6 units today).

I am wondering is there some kind of technical reasons behind this or is it so "suay" that all 6 units are facing a faulty air conditioning system?

Besides that, is there any well known problem for these Sonatas? I searched google but mostly are minor wear and tear issue. Of course, I would hope to get to know more about these cars =)

Thanks a lot Sifus =)

Ohhhh ok ok ~~
This Kimchi car second hand year 2011 is actually quite affordable. Price around 65k +/- ~~ Price drop for second hand car is sharp haha~~

I think I will have to send the car to the workshop and ask them to do it haha

After a week + battling with the Sonata AC, here are my findings.
I changed the Compressor (recon)
Changed the Condensor (new)
Flushed the AC system
Changed the Valve

Aircond now works perfectly.. sometimes with flaws:
Reduced "coldness" when stuck in major traffic jam
Sometimes could hear either "refrigerant" or "pulley" sound when AC is on (dunno where the exact sound comes from but no leaking of refrigerant)
ONCE. the AC completely shut down and blows hot air. I shut down my car, turn it back on and the AC returns to normal (like how you boot the computer and things go back to normal)

I dont know what else to do. I am lost lol ~ Bring it to workshop to check, cant check anything coz AC is perfectly fine. Hiccups a lot. But overall, I am still loving my YF haha
