Air Con Pump Problem


Recommended Posts

Ive been having problems with my air con pump lately.

When the air con is turned on, the pump/compressor makes this noise (about 8 secs in)

Please wait a few seconds for Video to Load!

looking at THIS it looks like I need a new pump/compressor.

Does anyone have any ideas on whats wrong?

ive been qouted £570 new from japparts and £155 used from need a part (lexus parts gateway)

I cant seem to find anywhere else that can supply the pump.

Does any one know the part number?

So it is the compressor making that horrible noise ? That does sound pretty bad, and the troubleshooting guide does seem to indicate that replacement is required :crybaby: . It does say if the noise is just coming from the clutch, then only the clutch needs replacing (compressor clutch, that is, of course).

How about a breaker's (lots on eBay) ? If a car hasn't had too much front-end damage then you should be ok.

Looks like the compressor change with the 2001 update, sounds like you've got an LE model which would be one of the later cars, i.e. later compressor. The part is 88320-53020 for the later compressor.

When the noise starts, does the nose of the compressor stop rotating or slow down?.... The fact that the compressor runs for a while quietly might suggest that there is a blockage in the aircon system... Pressure builds up and causes the compressor to lock up.... could be a blocked drier or themostatic expansion valve but this would need high and low pressure readings.... Of course it could be the compressor that is stuffed... If you fit a new compressor, then you will need the system stripped and flushed and you will need a new drier and fresh lubricant too, so it may pay to have a decent aircon specialist check it over before you splash your cash....

If it is the magnetic clutch or main bearings, is it easily repaired, or shall i just get another pump?

the thing with getting a used one is you dont know how long it will last, do the pumps normally pack up or are they reliable?

Thanks for the part number steve, just found a site that you probally know about already.

to be honest i'd get the pump the boy will prob offer you a warranty with it.

transporter the reason it goes quiet then loud again is the aircons going on and off like it should.

ps to swap the pump its easy but you will have to get your a/c gas recovered from your system and it willl be cheaper buying a pump than the seperate parts then paying

more labour to swap all the bits over.

the noise starts when the a/c is turned on (thats what you hear at 8 seconds, then its turned off and then back on again).

looks like im gonna be spending some money then. Got to get tax end of this month (best hurry), mot in a couple of weeks ( mintex front and rear pads, and front disks being ordered) and insurance in a few weeks, And now more money on the A/C (cant wait for the football season to start so i can start gettin paid again).

If i get the a/c gas recovered when i put it through the mot, will it be ok to drive about without using the a/c?

That way i can replace the faulty pump and take it back to get regased later on

All the part numbers are here, which is probably what you've already discovered.

Make sure you know what you need to replace though. If you swap the compressor and find out the problem was really the clutch (which is also pretty expensive), or vice versa, then that's going to be even more painful.

the unit the boy is selling on ebay is complete so it will just be a swap over job matey.

Right.... So the aircon was manually switched on during the video.... Then your compressor is shot... If it was the clutch bearing then it would be noisy with the aircon off.

As stated before, have the system flushed, new lube and a new drier or you could well be back to square one very quickly.... It's kinda like fitting an new engine and replacing the oil and filter from the old engine

When a compressor fails metal filings get carried round the system and need to be removed.

If you have the aircon pumped down then you will be able to do the required work at your leisure... Do be careful though as refrigerant can outgas from the lubricant and a small positive pressure can build up again so mind your eyes when you remove the pipes...
