My myvi car aircond not blowing cold air. After checking in automotive workshop, need to replacement cooling coil, walve, condenser, compressor and quote Rm2000, is it a normal price?

usually compressor still can use; that thing quite hard to rosak. I suggest u better go and check at other workshop la. Like my case, once this guy asked rm800 to replace compressor / hose / etc. Next i went to Sato, just refill gas and replace some hose, <rm100 only.

which model myvi? my guess its first gen?

im not sure "normal price" as parts can come from both ori, recond.

you may get a 2nd opinion from well known shop Hinly in PJ.

Complete replacement would only means black oil issue. If really is black oil then yes. The only way to fix is to replace whole AC system. You cannot replace part by part as the black oil is like a virus. As long as the virus remain in the system, it will continue to spread to other system if you only replace one part.

Price is about right at around 2k depending on parts you get. Used, oem, ori and so on.

Most workshops will recommend changing to more power compressor (Alza) but you should stick with original or oem myvi compressor. Bigger compressor will means higher FC and more work for the engine.

Good luck.

seems like u got into a black shop... they will dismantle everything and tell u the price to fix... please go other shops to check...

Thanks for everyone advice, mine one is first gen myvi, I do went to another workshops, some shops said its only compressor & condenser issue and quote me around 1600+.

My usual go shop said mostly due to cooling coil issue, because the external valve have many dust and it went black, the compressor is about to burn too (but not the main issue) and suggest me to change cooling coil for RM1000. After change the cooling coil, normally issue will be resolved. But the compressor not sure can last for how long. So if change with new compressor + new condenser + cooling coio + valve is about RM2000.

What is black oil issue?

Means the A/C compressor oil totally kaput.. A lot of people until today still did not knew that A/C system got compressor oil (Google PAG46/100 oil) circulating with the gas around the system and need to be flush/service time to time (At least every 2 years or 40k). The compressor oil is the 1 help lubricating the A/C compressor, when new the oil usually is light yellow/green/transparent depending on type/brand. Once too long neglected, gg compressor oil (turn black) = gg A/C compressor = gg whole A/C system as debris or dirty stuff will travel the whole A/C system and hard to clean it manually. So most A/C repairer see this condition, will recommend complete change..

need vaccin for it

oil is flow along with freon gas rite

Also to note, myvi first gen (aka old myvi) is notorious for black oil issue. The reason is still unknown but usually cause didn't go through proper service intervals.

Be also very careful and ask the pomen proper questions. A lot of AC workshops will say to just change one part and save cost. I am not sure whether they don't know about black oil issue or just want you to keep going back to them for business. Regardless what they say, to be safe I would recommend to change complete system. Unless the pomen can confirm it's not black oil and will warranty on the fix. Cause if really black oil, changing only 1 part will solve the issue only for few months.

Cheap

My car also black oil (not myvi king) and pomen macam saying something like change whole set but after done i look at the piping still looks same (dirty).
Pomen also mentioned dont recomend to do flushing instead change whole set but bill listed flushing too. So im wondering if change whole set does it need flushing or i got scammed?

What is the part called anyway?

The bill listed was condensor and compressor.

The 1st gen myvi i am driving also blew non cold air few months ago. My problem was cooling coil leak. That has to be replaced. They also serviced the blower fan, replaced the cabin filter, changed gas. All in is RM700.

Many years ago i got the same car AC serviced because the AC was blowing foggy air instead of clean air. The AC is just averagely cold. That time they replaced a corroded pipe, a valve, clean up cabin blower, clean condenser, change compressor oil and gas. All in was RM1000.

The reason it did not breach RM1000 is because i did not change the radiator fan motor and radiator plastic housing. That was highly recommended, but i skipped it. End up 2 months later, have to pay another RM 600 just to change those when the car was over heating....

What your mechanic means when not doing flushing only is just servicing the AC by changing the oil and gas. No changing of parts. When you change parts, you will need to refill the oil and gas. Not really flushing but adding. Still costs involved in terms of that.

As for changing complete set of AC, it really depends on the communications. Some pomen will mean changing EVERYTHING but some only means changing few parts only. This really need to be listed out properly and agreed on before work commence. Things like expansion valves and drier filter are parts that must be changed and sometimes not communicated but then suddenly kena charged. For black oil, you can either change the pipings or chemical wash them. Still something extra.

What the heck replacing everything!

That is lazy workshop that does not want to find which part is faulty. Go to other workshop

Easy job. More profit. That is the business target

This is the bill

Labour for checking, remove & change compressor & condensor RM180
Flushing with nitrogen & chemical solvent RM80
Compressor Denso RM1500
Condensor Denso RM520
Coolant RM40
Refill gas, vacuum + oik R134A

Should be more details breakdown?

So chemical wash is another term for flushing right?

what if the aircond only not cold when stuck at traffic jam or idle but cold when moving.
is because less gas ? fan blower not hard enough ? or relay is not good enough to kick in compressor when temp is hot ?

To answer your question, we are not actual mechanic or A/C specialist. Please go to a proper workshop to check it out.

Can be from a lot of reasons

- Low gas
- Fan not moving or getting slow
- Compressor is going to fail

Yes, that is chemical wash of the pipes and things didn't change.

Strange didn't show listing of expansion valve and filter drier. Maybe the pomen lump into other parts.

Also how come cooling coil didn't change? Lazy to change cause it's too much work? The issue will come back in less than 1 year. My car didn't fix properly and the AC issue already start showing. But it's already 2 years. Now using until it not cold anymore. Then change whole set.
