Air Con Cutting Out After 10 Mins

[RogerA]

Hi, I've owned my 2002 RX300 since 2006 and just about to change it for an RX400h. I'm trying to sort out all the minor problems with my RX before I put it up for sale privately and I am hoping somebody can help on this one.

My A/C works fine for the first 10 minutes or so after switching on and then the A/C light above the button starts flashing and the cold air is replaced by normal outside temp air coming in. I've had the system topped up and re-pressurised including a new condenser fitted (as the old one was leaking apparently) but problem persists.

It's like the system reaches a certain operating temperature then drops out. I'm wondering if there could be a faulty sensor or something simple?

Any suggestions much appreciated

Thanks

Roger

Hi, The only thing I can think of is maybe there is a filter that may be blocked causing the system to shut down because it is over heating, sory but I haven’t a clue were the filter is, hope this may help.

Thanks fro the quick response. There's an air filter behind the glove box which I have cleaned but maybe a main air intake that I should check out. Thanks again.
