This is the point where his words gives me the red sign. From what I heard (at least) a new compressor comes with a magnetic coil ( or clutch ?). I have looked up online, clutch cost 330 and compressor cost 950.

He said he discounted the compressor, but then charge me 400 something for clutch.....

If yr compressor clutch is kaput, how he able to test either the gas pumping rate is good or not on low side and high side.
Pressure test means A/c man pump some refrigerant o N2 gas into system and observe from gauge either there's any leak or not after observe maybe around 2 hrs.
Some car have low pressure switch. If run out of refrigerant due to leaking, it'll prohibit the compressor from running. In this case, you won't see the compressor clutch is engage.

Ideally If micro leaking case, you'll feel your aircond cooling effective gradually not as cool. If it's overnight not cool, then it's not due to evaporator leaking.

Normally compressor internal damage, it's advice to solve it immediately to avoid the the contamination of broken part damage the evaporator.

Remember to get the a.c. man do flushing during replacement of compressor. Else u may seeing evaporator damage in short period of time after replacement.

I see. Now I am starting to doubt how he was able to say pressure good if the clutch was really broken....(I actually doubted him in my mind)

The clutch was not running and he pointed out the clutch to me saying it is burnt because it is in red color. (I asked my foreman friend and he said if the clutch melted it will look like a red chocolate donut)

Now I assume the evaporator you are mentioning is also called Condenser ?? Because the uncle did say he helped me to flush out the condenser. Otherwise my air-con will not be cold again after few months.

Learned something new through your post. Thanks sifu.

and also my first time to see compressor without clutch. and to make it even more fishy is..... "no warranty" for both items, for real?

Wah..

Original Compressor and clutch seperated & no Warranty for both !!!.. speechless

Aih.... my bank account is bleeding and i am crying

Just hope that both compressor and clutch are really ORIGINAL. If it is recond, I am going to spread bad news all over the internet and make sure that he will no longer get any customers.

is the shop under denso authorized shop anyway?

Now key is it is working good and hope lasting.

If can, make sure you change the cabin filter at least once a year or every 20k km. sometimes it is very dirty after 6months.

The uncle (owner i assume, since he was alone) said his shop is genuine authorized DENSO service centre. But I did see some products like Cool Gear and likes of Thailand/China product in his shop lah.

So far its been a week, air-con working fine and feel cold under hot sun (which it already was before it broke down). I will make sure to update once a week here to let people know.

Thanks for the info sifu, will put up a reminder in my list. In fact I changed mine exactly one year ago in Perodua SC.
This part I really need your knowledge sifu.
The uncle told me he changed one original for me, claimed the one im using when it broke down was " No good " one. He claim it was too thin and full of tiny holes that dust will get in easily.

The one he slide in was exactly the same one when Perodua SC person said my old cabin filter very dirty that is why P2SC changed it for me. Samples below.

<< The one he said no good.

<< The one I was using before P2SC changed it for me, and this is also the one the uncle changed for me now.

This one can fit alza?
The boss said the vios one too small, must use vigo type

Well even an authorized denso service center would con you too. I remember I sent my old myvi few years ago to denso authorized dealer in Glenmarie and he demand more than rm3000 to fix the aircon issue. I end up sending the car to a shop in Kepong and get the aircon fix at rm600 and its working fine until now.

the "thick" cabin filter price around rm20 only at spare part shop.

I am using the 'thick' white one since day 1. Recommended 1 year change once, but also check every 6mths if can. Sometime very fast dirty.
Spare parts shop shld be cheap..like <rm20. Lazada also have lots of it..

Thx

rm3000 is outrageous pricing. even sc won't cost that much either.

Org Kaya pakai Myvi ,, repair Aircon denso ..👍

Then I think I got con lol....

Then I should ask people to stay away from this Denso shop lol...

I think it will be good to 'keep' a list of good workshops and everyone maintain it.

Not just AC, but also other good or bad SC... etc.
