I would be interested to know how many kms your vehicle has covered when your aircond compressor failed. I would like to know what vehicle and at what kms the failure occurred and is replacement rather than repair the most cost effective method of solving the issue. My vehicle is a 2002 3litre diesel with 145000km but I have only had it for 20000km. Interestingly my previous 1994 Rodeo which I had from 60000km to 280000km never had a failure. My compressor is not turning so I assume the clutch gas failed probably because the compressor is siezed but will get it checked out.

hi mate

I had a comp fail at 65000 on a 2003 hilux 3L replaced it with a new one it is almost impossible to rebuild a air cond comp. At the moment i have a 99 4500 gu patrol 277000ks with original comp still going strong runs around 4 to 5 degrees at the vent.

Hi Scott, yes I was wondering whether the quality is better on vehicles like the patrol. I had assumed simply replacing it would be the way to go. I figure compressor clutch failure alone is not the probable cause, more wishful thinking.....cheers Peter

Don't assume that the compressor has failed simply because it is not turning. It is more likely that the compressor is not turning because the magnetic clutch is not energising.....apply a voltmeter to the wire to the clutch to see if there is any voltage being applied.

If there is no voltage to the clutch when the air cond is turned on then it may be due to an electrical control fault. Another reason for no power to the clutch is if there is a leak causing loss of refrigerant in which case a pressure switch on the refrigerant line will interrupt the compressor as a safeguard against the compressor running dry. A refrigerant loss can be from a hose or from a leak in the condensor or evaporator.

There are many possibilities for your problem and it may be best to get an auto fridge mechanic to take a look at it before shooting from the hip and incurring unnecessary expense.

Good explanation here Allen.

I had my aircon fail while my vehicle was under warranty. Compressor clutch would not engage so took it back to dealer. They replaced a number of items after having my vehicle for 2 days they gave it back to me having supposedly repaired it. Drove it out of the dealer, still no go!

Took the vehicle home having booked the vehicle in again & fixed the problem myself in 10 minutes. It was a broken wire to the pressure switch you mention in your description. The switch was located very close to the front plastic grill so was quite vunerable.

Boy I would NOT have been happy if I paid the dealer for 2 days labour & parts to NOT fix the problem!

interesting concept but to make them last you need to use them as often as possible, it keeps the seals working and keeps the "oils" flowing and doing the job, that is to make them last .....

i use my air con all the time, and i only got 150 000 kms on the clock before it seized the compressor, pity we were nearly at Ayres Rock when it happened, because air con would have nice
Vehicle is a 105 series Landcruiser, and i've heard of a few others doing similar klms when theirs went also. i think it's just pot luck these days as to how many klms you get before something like this breaks.

Brothers Rodeo compressor failed at about the 220k mark. Complete failure not the clutch. Replaced it.

Oh yes. From what I understand (may be wrong) its best to run them frequently even in winter. The gas keeps the seals from drying out and the system lubricated.

I have had many many vehicles over the years and have never had an AC compressor failure of any sort. Many years ago, a friend of mine who was an "after - market" auto AC installer, told me if I never turn the AC off, the compressor should last indefinitely. So that's what I've always done ... with never a problem. The movement of the refrigerant gas is what keeps everything lubricated.

Mine died last winter on the way to Ayers Rock also, roughly 150K. (Must be something about the rock, Rumpig?)

Fortunately it was winter, so we could get by without it until we got home.

Compressor was stuffed, there was a pinhole in the evaporator, replaced comp. and evaporator.
Vehicle is 2002 update HZJ105.

must be something about 2002 HZJ105's going out to The Rock with 150 000 klms on the clock aswell by the looks of it. that is the same year, model and klms as mine.

My 1991 HDJ80 had its first one go after about 250,000 on Great Eastern Highway between Kalgoorlie and Perth. Second at 340,000 last year between Kununurra and Halls Creek towards the end of our Gibb River Road crossing. Didn't have it repaired in Broome due to the exorbitant cost, despite living and working up there for last year's dry season. Replaced with a recon in December of 2009 at 355,000, before breaking at 364,000 just recently, a week after the statutory warranty expired.

The second time it happened after the vibration dampener broke apart, leaving the outer pulley suspended by the fan belt. I purchased a new number two pulley from Toyota, tensioned it correctly, and it worked. Drove to Northam, and noticed a quiet ticking sound, but still had effective air conditioning (much better at higher speed). Looked under the bonnet, the tensioner pulley had come loose, and the belt had turned inside out, so was still driving the pulley. The clutch had also broken.

My mechanic thought that the vibration dampener may have been broken by the air conditioner compressor starting to seize, which lead to the cascade I've just described. Anyway, I took it back to the group who did the compressor replacement a year ago, and after a bit of strong verbosity, they agreed to repair it under warranty.

So my car has had four separate compressors in her nearly 20 years of service. Mine gets run fairly continuously as well.

Moral of the story - buy brand new.

Thanks for all the replies. I had it checked out this morning and it seems the compressor is siezed. So I have it booked in to get a new repalacement and the aircond serviced so I guess it will see me out for the time I have this vehiclle. Didnt ask the price as I think I have to be pleased to find someone to do the jpb this time of year, I thinks its probable these high speed 4 cyl diesels will fail long before the 4.2 diesels throw in the towel.

Ive got a 2005 HZJ 105 (updated) cruiser and my compressor failed at 125000k
39 degrees in the back, vinyl seats, 90% humidity really good time to seize, and I mean seize, 2000 rpm going up hill when all the belts just locked up.
I argued with Toyota, that it should not of failed and even though it was out of warranty and came to a 50/50 agreement
Job total was around $1800, compressor, gas, labour, I don't think it is as good now as it was, but comes up within "specs"

My Rodeo 2002 TD had the compressor replaced in 2008 at just under 100 000 km. Cost just under $1000 all up.
I thought it was the clutch but turned out to be the compressor.
Hope this one lasts longer than the original.
