Aircond Compressor Failure

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.

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.

i have travelled 365465 k's no problem with the compressor. have had it regassed 3 times , changed from R12 - R134. 1993 80 series. a/c gets used summer amd winter

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'll go for 750,000, been re-gassed once.

My Gu has 310,000ks and my ex wifes GU has 450,000ks, both not regassed.. Michael

Previous GQ- 485000km, no compressor probs.
Current GU-298000km, same.
I run the aircon all the time.

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

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.

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.

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.
