My air con works well for a minute then blows normal air but not warm. I can see that the air con motor stops turning at this time. I had it charged last year and was working fine. Any ideas would be appreciated.

are there air bubbles in the dryer?

the system stops to protect the compressor
when leaking

There are bubbles in the sight glass, the air con compressor and rad fans now run for about 10 seconds before switching off. They then dont work untill you restart the car, then the same thing happens. I cant see any leak, there is plenty of green dye in the gas too.

first you need a set of gauges to read the pressures..and if it had a leak and you just recharged it..and now its low again..you still have the leak..if the system has dye in it...the light should show if there is any dye leaking anywhere..

I had something similar occur on my 00UTY a few years ago - air worked well for a while (between 30 seconds and up to 5 minutes!) then blew hot air.

I took it to a few places before my local Mitsi dealer arranged to keep it for afew days testing the air - as they couldn't fault it either. (compressor, gas, etc all ok)

In the end, it turned out to be a very minor issue - the auto clutch assembly on the air compressor had two slightly loose retaining screws. When the compressor clutch engaged, it wouldn't stay engage for very long at all, hence the hot air.

A few turns with the wrench - and the problem has never returned since! By the way, my air is running beautifully since new (apart from this minor glitch).
Has anyone had to get the aircon system re-gassed? Mine is 10 years old next May, with over 350,000Kms on the clock - and still using the original gas.

The air is still blowing at a measured 3 degrees celcius at the vents!

Cheers,
00UTY

Yep, took the wheel arch cover off and peered at the pump and sure enough the nut on the end of the pulley/clutch had slackened a little. Sorted.

Worked well untill my fan belt snapped and wrapped itself around the air con pump and the alternator wrecking both. Belt had only done 60k miles. Really shocked it caused so much damage, the alternator is making a terrible electrical burning smell and the air con pulley shaft/bearing is making a bad noise when turning.
