Different Aircon issue

[tez Lurker Find all posts View Profile Close tez]

Seems to be topic of the week?

My aircon worked yesterday but not today. All seemed fine when I parked it last night, but today there was just hot air. I have searched the forum and tried changing over the relay from fog lights to Mg/Cth without any luck.

The lights are on on the dash.

The magnetic clutch is not engaging.

Anyone have more ideas before I go through the hassle of booking in with Toyota (still under warranty)?

Thanks

I recently had an issue with my A/C cutting in and out then not working which i posted about recently,the problem seemed to only raise it head on plus 25deg days, I went thru a process of solutions before solving.1ST step had system regassed [aprox 600grs],problem persisted air cutting in and out then compressor stop working,2nd replaced replaced said relay with new one $20non genuine [nofogs to swap with on GX],still not operating, cutting in and out, 3RD had gas pressure checked and removed approx 50gr of gas, problem now seems to be solve as had no further problems in last 4 weeks.I found that i needed to present car at auto elecy on hot days with problem present to assist in solving it, and he thinks that the relay was failing when under eratic load ie due to pressure problem causing some pressure sensor related to system turning compressor on/off frequently when temp rises and shutting off compressor on plus 38deg day, which in turn plays havic with relay.It sounds plausable and is ok now but as stated he needed to see it on hot days playing up to problem solve.
hope this sheds some light on your problem
ta Russ p/s mine is a 1kz diesel

Fixed! Well eventually...Toyota rang to say that an o-ring had failed and let the gas out. Went to pick up and it wasn't working again. Apparently another o-ring had failed underneath?

Anyway, all cool again.
