Inb4, dunnoanythingaboutcar

my car's aircond has been abit upset lately. i noticed that the car aircond will only give cool air when i am driving the car (as in the car is moving) but if the car is idle, the aircond will no more give cool air out but warm air instead.

i noticed too when i on the A/C (aircond) system and tekan minyak, there will be a strange noise that come along. the harder i tekan minyak, the louder the engine noise will be (that is normal) and also the strange noise.

i asked few people around (through phone, coz no time face to face) and they say is the aircond compressor / aircond motor problem. are the a/c compressor and a/c motor even the same thing?

and how much would it cost me if i want to change it for recond together with service included? i had a quote for RM400++, anything i should take note of? especially on the compressor/motor as i will be taking a recond one.

its a kenari. last time service i think within 1 year time. changed all the 3 "belts" + service. how i check the pressure? need to workshop rite?

and your oil is what oil? engine oil i just changed 2 weeks ago. bearing?? where de bearing? lol.

i see. so basically i still need to bring it to workshop to figure it out eh? hahaha.
any idea on the recond compresor price? and also when they say a/c compressor and a/c motor, is it the same thing?

Things to check for old car a/c system and goto car aircond shop, not workshop.

1. AC Gas - If low, top up. Usually can last up to 2 years. If 3 months lose gas already, ask them to check if got leakage at pipes or joints. they have gas detector to do that if u go to proper car AC shop. Gas can also leak through the gasket of older compressor.

2. Low gas cutoff sensor for compressor - Some idiot usually advise to bypass this sensor when it's faulty. What will happen is when your gas is low the compressor will keep on running spoiling the compressor. Happens to my old car last time, change compressor 3 times because of this.

3. Thermostat - rarely spoilt, but if spoilt will cause your condenser to over cool and makes water in the condenser freeze to ice. Air flow will be blocked and no air will come out of your blower until it melt again.

4. Compressor - The heart of the AC, if older than 3-5 years usually have issue like gasket leaking or wear and tear on the piston. Will die really fast if the low gas cutoff switch have been bypassed.

5. Condenser - Place where the air become cool and hot air is absorbed. Rarely need any attention because a normal cleaning shoul dbe sufficient if it's too dirty. Only need to change when there's leaking but only on really2 old car.

Always try 2-3 different shop to troubleshoot before you repair, checking is always free and it's good to have a 2nd opinion especially if you're not familiar with the shops. Ask the problems and price for repairing it. Compare it with other place.

woa very informative posts

TS seems you are having a problem at idle, there are a few posibilities like already mentioned earlier.

i will look at condenser seals, radiator fan, ac fan. i dont know about a kenari but most cars have a cutout when the idle compressor discharge pressure is too high. when this happens AC will not function.

i think this is what is happening. coz i keep hearing psst psst sound when my car is idle. and i can see my rpm playing along. for example, when idle, let say i tekan minyak so that the rpm is at 2000rpm, when the psst sound come, it will go down to maybe around 1000rpm++.

any idea on this one? so i shud just off my a/c for the time being until i bring it to check? gosh the heat..

i think so. it repeat every 2 to 3 seconds. and if put idle and the air become warm, when i start moving again it will not necessarily will be cool again. sometime it just stay warm all the way.

lets say its the problem as what u mention above, what is the thing that got broken?

i dont think thats the case.. the last time i bring it to aircond service was like almost 1 year ago... but i did went for engine oil change + service around 2 weeks ago... dont think they did anything to the a/c system?

ok. just wanna know what will i need to know. i dun wan kena sembelih by those ppl saying the whole a/c system rosak need overhaul or smth.

if leak, what will be replace? and around how much need to spend?

and if that so called piston rosak, how much need to pay?

normal compressor can survive 3-5 years u mean is recon compressor is it or after repair?

ya.. gov no control the price thats why. they need protong to survive...

coz i think my compressor also quite long no change d... decrease power nvm, at least still can blow out cool air ok d la... i tak banyak macam one 

me 60 years old. u belip?   

yeah, but i know it really condem or wat lol. jangan jangan bring to check, they cincai give few reason then say compressor broken need change.. 

haha. so i'll just let them check it first the decide eh?

If there is no gas in the system, can they check for leakage, for free? Or is the only way to top up, and then check for leakage? They will charge then right, since gas has been used?

The shop guy put his finger on the compressor and say "see, oil leak, compressor rosak,  must change new one. RM400". They say the compressor is one single unit. Cannot repair. Must change the whole thing. What do you think? Scam? O-ring?

Ah they use bubbles is it to check? The one i went last time use an electronic sensor to detect the gas. It have a long probe like thing and will beeb loudly near leakage area.

wow really canggih la nowadays, my old car last time the leak mostly at compressor (change to recon) and pipe joints. Must be cause i did bang the car a few times before 

But they fixed the joints, not sure how they do it cause i spent the whole time waiting in a cyber cafe playing online games 

last time my compressor spoil cause some smart alec before bypass it using a jumper. With leaking on the pipes joints (minor) and the old compressor gasket, the compressor keep running even though it's low on gas. Costs me a fortune changing the compressor 3 times. Only the trusty shop at bangi spot the problem and advise me to change the cut off switch. It's not that expensive too, blardy hell.

Really owe the towkey big one for doing a proper check and spotting the problem for me.

nah no problem, i've seen worse. If i'm not mistaken the sensor is only rm80 - 150. I've spent so much finding good shop and changing almost all the aircond parts last time in the span of 5 years.

It's an old 89' ford 3rd hand, the previous owner is really terrible. After 3 month i got the car, then engine oil sump gasket leak. My mom is furious seeing a lot of engine oil on her nice garage floor 

I'm sure he's also the one that messes up with the bypass switch.

I've changed the thermostat (cheap one, just hide it under the dashboard), condenser (the shop guy con me, shouldn't have changed it), Blower (fan not so strong), Compressor (so many times because other issue is causing it to spoil and they fail to find the cause)

Now i think i'm pretty expert already with old car aircond system and try to help others not to undergo the same issue like me. 

Hi, can you kindly share out the thread link ? My compressor is making loud sound too, need someone to fix it back.

Thanks for the details. If im not mistaken, my dad brought my car for an A/C service few months ago. Thus, I'm really looking forward to have my compressor being sort out in the similar way as urs.
Yea, quite loud. Actually, it was my mech whom told me about the loud sound. He mentioned the compressor was force pulling it due to very minimal amount of oil there. I'm an A/C nuts, thus not really sure what kind of oil is he talking about. But all in all, I can hear loud whining sound coming out from the compressor part. How much is the cost to repair a compressor normally ?
