    Toyota Landcruiser A/C Problem

    Had my 2000 Cruiser since new – 199,900 km - old but lovely condition – except the AC stopped making cold air
    Poor old Cruiser – but we have an ongoing love affair, and it has to see me out!
    Took it to Toyota – they have done all the diagnostics stuff over a couple of hours - they tell me the A/C compressor, clutch pulley, TX valve and receiver drier needs to be replaced – ex Japan - $3910 plus GST in about four months’ time
    Does anyone have any ideas on how it could be repaired at a lower cost?
    Looks like there are compressors available on TM at much lower costs – but who would fit it?
    Thanks for any help and ideas

    Try changing your cabin air filter first, if you haven’t already.

    Um, this may take more than one post.
    Two common faults are the tx valve fails shut, this may have caused the compressor to burn out.
    The other common fault is the air gap in the compressor clutch gets to big.
    Can you advise if the clutch engages on the compressor?
    The pulley is driven by the belt and spins all the time, the clutch is the bit in front the engages as it cycles on.
    Might need a road trip to Wellington

    To answer you last questions, you can do it with a little guidance. I may still be able to get a much better price from one of my old contacts.

    I mite be able to help you there mate, do you know if it’s a 1hz engine or a 1hdt turbo model or twin cam or petrol? I used to fix cruisers and can possibly diagnose the fault, get parts and maybe get system regassed by 1 of my auto sparky work mates with an aircon ticket for a shitload cheaper than what Toyota quoted. I’m in waihi beach area, so if I get near Tauranga with spare time I can hav a sqizz over nxt few days, or pm me your number and I try figure it out

    Step 1, get the fault(s) individually diagnosed - Toyota are in the bis of not having vehicles come back from repair so will replace the lot with brand new at the requisite price. They don't typically recon parts as it's not a dealer supported option in NZ and they probably don't have the gear available to test what comes out anyway, and they don't chance the replacement parts on older stuff they can't check. It's a sound business decision by a dealer, as it's just not worth the grief from the customer and also not worth them carrying the tech time to fix the issues at their cost.

    On the other hand, do you need all that gear replaced? Probably not, and with the correct id of the fault you can likely do the work to remove and get the bits sorted.

    With the pumps, there are a few main culprits on them - clutch engagement (air gap), magnetic coil in the clutch failing so allowing the drive pulley to slip and not function correctly, pulley 'V' worn which means the belt slips (usually squeals but not always), main front shaft seal wears out allowing the gas to sod off, and the front bearing wears which allows the shaft to either flop and lets the gas out or the front shaft can chew out. There's a few check valves and bits internally that can shit themselves but, generally most AC pump failures are at the front end where the power arrives.

    Down from there, TX valve dying shut or just generally dying, and receiver/drier (these bits are not normally that expensive so probably best to replace them at the time). On from there, the pipework itself can fail, as well as the in cab bits but if Toyota haven't quoted that it should be good.

    Pretty much from there, your options are get a wrecker AC pump usually a 3 month warranty, or get yours rebuilt or possibly you may be able to find an outfit that will do an exchange service with a rebuilt one for yours. The exchange would be the way to go if you can find someone doing that, followed by rebuilding yours and then a wrecker part but an option is getting the wrecker part and leaving yours to be rebuilt (which will get your system back up and running quicker). I'd def replace the TX and receiver/dryer though.

    Usually a leak down pressure test with the uv dye will show where leak is, and then just repair the parts that’s linked to leak, but usually when it leaks the compressor cooks itself coz of gas pressure differences and produces moisture thru system. Simple way of telling is by pushing on the Schrader valve on hi pressure side and seeing if still has gas, then generally cheaper fix, if no gas then it’s leak test and bit more involved. I will try get my mates number and forward it to you. He’s a mobile auto sparky in Tauranga and does air cons and we worked together fixing land cruisers for years. He be way cheaper than Toyota, fast and provide you with some good yarns and laughs.

    Morning Time Out. I cant help with the aircon but Ill just fill you in on my experience with the local Toyota dealer. Had a fuel delivery problem( pump) in an Altezza. Took it to the local Toyota dealer and said I think the fuel pumps shot , can you give me a quote to fix please. They came back with a quote for over 1300 dollars , said the pump was shot and charged me 130 dollars to tell me that.
    I said no thanks , took to local garage , cost 220 dollars to replace. They said to me it was the easiest pump to replace they’d seen ,lol.
    I emailed and messaged them asking why the quote was so expensive but they never replied. Funny thing was , the Mrs was looking at buying a new car at the time ,loved the toyota models. When I picked the old car up I made the mistake of wearing my red bands and asking what the new ones were like. They didnt show much interest. Mrs drives a Kia now.

    Another option for low gas (if thats an issue ) is to get a top up can from supercheap ,follow instructions . My 1999 toyo had poor air con , was working a bit but not enough . I spied low gas at the sight glass...bought the top up can and gauge ( about 70 bucks ) did the bizz and its still going strong 4 years later . Doesnt fix the leak but I guess by the weight of the can I have 2 more top ups . 134a gas .

    It's amazing how many systems 'weep' a little gas from somewhere that you just can't find. Had one in an old Safari, low gas and topped it up. Leaked down over about 9 months, couldn't find a leak anywhere but scored a rebuilt AC pump and refittid that with a new receiver/drier and the mate regassed it. Lasted about a year, and low on gas...

    Recharged it and went through everything, couldn't find a leak and checked the thing religiously once a month and was still leaking down when I sold it. They just wind the windows down now. AC leaks can be a pain in the arse...

    Thanks for your help Guys – I expect that Toyota would provide a quality repair – but the cost is likely to be at the top end - but in saying that – I have also had some bad local dealer experiences recently with three trips to fix a leaking CV boot – messy!
    Toyota have been kind to me with this car – soon after I got it - I noticed the front tyres were scuffing badly - I gave it back to Toyota NZ in Palmy for a couple of days to test for better alignment on NZ roads - they said to let them know when they were worn out and they would give me a new set - seven years and 60ks later - they sent me the new tyres and it just cost me installation
    At about 65ks - it started “running on” when I wanted to stop - quite disconcerting - back to Toyota - torque converter needs replacement - Toyota paid for it and just cost me installation - I recall it was worth about $9k from Toyota
    I will always drive Toyota cars - service is generally great but the cost for this job looks high
    I don’t know what is under the bonnet – but maybe this pic will help and the pic of the diagnostics yesterday
    Thanks again for any ideas for a lower cost solution

    Ahh yep, that kind of exactly lines up with what everyone else has put up, good thing is no leak. I'm not an expert by any stretch, but I'd say if it's holding gas thats a good sign. The clutch replacement needs to be done as it's fairly easy to diagnose that if it's stuffed. The low pressure being high is indicating a system issue, either the TX valve is suspect or the receiver/drier is past best.

    Now again no expert, but I wouldn't be doing a compressor clutch in the vehicle - it's easier to pop them out and get them on the bench. The problem with this is that the same belt runs the cooling fan and probably the alt, can't see and can't recall off the top of my head on those but this means the vehicle is off the road while being fixed... Would make sense in this case to either talk to jamie who posted up above and see if he's able to assist with it and sort the bits or, have a ring about and see if there is either someone able to offer a rebuilt compressor on an exchange basis or find a wrecker part with a decent enough warranty and swap the compressor in - no issue with using the vehicle then as Toyota have removed the power to the clutch.

    You will at least have the vehicle to use then, while the hard bit is away getting sorted and can probably replace the TX and r/d and regas as well. Might hold for a few years, and you'll be able to get the original AC pump refreshed at your leisure. It is not a huge job replacing the various bits, just a little fiddly and a pain in the bum to get to a few of them.
