proton Posted June 11, 2023 Share Posted June 11, 2023 One thing after another with Vios, but it is 11 years old. Just warm air out of the vents, new air filters, put gas in it today, still not cold. Garage man said fill the coolent up but that looks half full still, shops shut today anyway. What else could it be? 2 Link to comment Share on other sites More sharing options...

There is a wait because there is a queue... I admit there is a luxury element in going to a dealer, which I have come to like as I know things will be done properly... I have a friend who likes to go to these little shops - they are actually not much less expensive and it goes on for months as things don't get fixed... it ends if fights too. And often after all the visits, much more expensive than the dealer, in the long run... But, this is just my experience - I have owned cars for many years as I started at age 16 and now am 135 years old. 6 3 Link to comment Share on other sites More sharing options...

digbeth Posted June 11, 2023 Share Posted June 11, 2023 if the system has a leak and the compressor ran dried, you're probably gonna need a new compressor 1 Link to comment Share on other sites More sharing options...
Popular Post xtrnuno41 Posted June 11, 2023 Popular Post Share Posted June 11, 2023 Ah there is the 11 year old rusty vios again, hahaha. Well my wife's 20 year old vios had also that problem 2 times when i was there. Doing nothing, well just switching the knob on/of several times, but didnt work. it came back after 15-45 minutes or so, but random. As switching didnt work (bad connection in switch), I was thinking about a bad wiring in the system. Somewhere it would disconnect and by bumps get together again and working then. So wiring or maybe the cable connectors on compressor or switch, oxidized? Maybe the valve (choosing normal air or airco air) is not working (also bad wiring to it, cable connector) Not in my case, as when running idle and airco switched on, I noticed there was not a drop in the electric power. And engine is more loaded then when compressor turns on. But only noticeable when stationair running. You could check that. Just sit in your car, start, put airco first off, wait until the auto choke has gone and it is in normal working mode listen and watch your rpm meter. Then put airco on and wait, listen if you can "hear" the powerdip. Also look at your rpm meter. IF you dont hear and see change in rpm meter and the car is just going steady in stationair and rpm, then the compressor is not activated and you have warm air. You can make it bit harder for the engine if you put on your lights as well, more load. Maybe you can notice it better then. 4 Link to comment Share on other sites More sharing options...
Popular Post Lacessit Posted June 11, 2023 Popular Post Share Posted June 11, 2023 I have a 17 yo Vios, It's just a matter of getting the refrigerant recharged, and checking for leaks afterwards. You need a competent aircon mechanic. 5 Link to comment Share on other sites More sharing options...

You need a competent aircon mechanic. I have a 20 year old Vios. Most reliable car I've ever owned and bodywork still good. The aircon packed up a few weeks back. Turned out to be a leaking hose on the compressor. New hose and coolant fixed it but for good measure I had the coil removed and cleaned as they get very dirty and slow air flow.. If the aircon only work intermittently, a loose or bad relay is usually the problem. Easy to check. Plenty of youtube videos on Vios aircon repair.

Coolant goes into radiators, refrigerant goes into aircon compressors. Coolant is water with additives such as ethylene glycol, which raises the boiling point and depresses the freezing point of water. It usually has corrosion inhibitors as well. Refrigerants are organic compounds, hydrochlorofluorocarbons, commonly known as HCFC's. They are gases at ambient temperature and atmospheric pressure. My apologies, I am in a pedantic mood today. 2 1 Link to comment Share on other sites More sharing options...
thailand49 Posted June 12, 2023 Share Posted June 12, 2023 Here is my experience with my first Toyota here 2006 Yaris which is basically the same as your Vios. You are correct that the dealers over charge for everything they in majority of cases replace not fix problem. After 17 years I still take it to the dealership once a year for service oil, because the Yaris has a computer system they plug in to detect problems. Yes it is ignoring when waiting they come up and recommend changes like wipers, battery, tires when not necessary just last year told to do brakes just a few months ago I had them replaced at my independent shop I use. Basically the Yaris no longer under warranty I use them detect problems then take it to my other shop. My truck still under warranty last year I replaced the battery shop forgot to mark the purchase date at service they saw that it wasn't said testing the battery only 60%, I just say thanks and I would take care of it, their price 4000 replacement same battery more amps 2400. Years ago I had the same problem with A/C, I took it to an independent guy right outside the dealership tested said have you ever cleaned the system unit Answer was No, he said no leaks but will recharge if it still blowing warm that is your problem. I ask him how is it done and how much then 1400 baht he pointed at a Vios, the entire dash was taken out to get to the unit to clean. I looked at all the screes removed to the dash it was scary I though no way can anyone put it back together without something being wrong. I told him let me think about it Because in a week I was taking it to the dealership for oil service. At the service this time did notice said " A/C " very dirty need to be clean I said how and how much? Good news to my ear he saw Toyota has a machine like a vacuum that flushes the unit without taking out the dash 1800 baht and recharged it was like a miracle drove off with unit on freezing. Five years down the row a number of problems with unit including motor slowing down although cold we were now turning the dial up to 3-4 for the fan. Replacement for problem was 18,000, I took a few days to research if I could locate a use unit since there are so many accidents vehicles are total but not all the parts I was unable in the end not wanting to do a piece meal replacing some unit although the vehicle was now ten years only had 80,000 KM, I had Toyota replace the whole unit 24,000 baht. Problem with small cars and being here in Thailand A/C are on blasting, my truck 2.4 rarely do I need to move dial past 1. Sorry that is long but I would get member recommendation for independent A/C shops I usually look for conservation approach if they quickly suggest cleaning without checking for leaks etc I usually politely leave. Good luck. 1 Link to comment Share on other sites More sharing options...

Tropposurfer Posted June 12, 2023 Share Posted June 12, 2023 (edited) 11 year old car, already re-gassed, if the freon gas in the air-con coolant system is topped up, and NOT leaking, this might mean the air-con compressor is done.

I'd take it to a real car A/C place if I was you. The coolant should not make any difference, cold air should come even before the engine would get too hot. As for using a dealer A/C cabin filter at Nissan 1,200b-- Lazada 185b delivered and looked stronger/better.

kwak250 Posted June 12, 2023 Share Posted June 12, 2023 The garage that said to check the coolant for the air con missed the other very important item. Blinker fluid Now this is often overlooked. 1 Link to comment Share on other sites More sharing options...
stratocaster Posted June 12, 2023 Share Posted June 12, 2023 When my Volvo's AC packed up I was close to a Volvo dealer. They took the car to an AC specialist shop as they said they know more about ACs than them. They diagnosed a leaking dryer, never a problem again. 1 Link to comment Share on other sites More sharing options...
connda Posted June 12, 2023 Share Posted June 12, 2023 You need to have the Freon topped off but you may have other issues. Best to have the A/C checked by a qualified shop. There are A/C shops all over the place once you know the signage. . Memorize this Thai script and look for it on roadside signs. It's a Thai transliteration of the word "Air" and is simple enough to remember: (Dear mods - I know Thai isn't suppose to be used in non-Thai forums, but in this case this script is more like a picture that the Op can remember in order to identify a road-side A/C shop. Thanks) 2 Link to comment Share on other sites More sharing options...

No advantage to visit a Toyota dealer (that's what they are). Just did the math: 2566 - 2547 = 19. So our first car, a Vios is a whopping 19 years old. Runs smooth and strong, no rust no nothing. AC is better than my 2011 Mazda. Edited June 12, 2023 by KhunBENQ 1 Link to comment Share on other sites More sharing options...
The Theory Posted June 12, 2023 Share Posted June 12, 2023 You need to find an auto AC repair shop in your area. AC gas leak could be the reason. Link to comment Share on other sites More sharing options...
