jlin101 Posted July 30, 2004 Share Posted July 30, 2004 the a/c light on my RX330 flashes sometimes--turning a/c or the auto button on and off resets it. Any idea? Quote Link to comment Share on other sites More sharing options...
SKperformance Posted July 31, 2004 Share Posted July 31, 2004 you compressor is locking up and will eventually die if not looked after Quote Link to comment Share on other sites More sharing options...
Sark003 Posted August 4, 2004 Share Posted August 4, 2004 All of this is an indication that the speed of the compressor is not matching the speed of the engine. Make sure the belt is tight. Make sure that the front of the compresor does not have any oil residue there. This was an issue with some early model RX's with the front seal for the compressor leaking. Also in wet weather if water gets on the belt and causes the belt to slip, It will cause this problem. Quote Link to comment Share on other sites More sharing options...
SKperformance Posted August 4, 2004 Share Posted August 4, 2004 not really a speed issue it is a sensor built onto the compressor for high pressure which disables the clutch and makes the a.c light flash Quote Link to comment Share on other sites More sharing options...

Drcoffee Posted August 6, 2016 Share Posted August 6, 2016 You need to check your pressures, high and low. It could be low on refrigerant. Quote Link to comment Share on other sites More sharing options...
Jordan Cohen Posted August 7, 2016 Share Posted August 7, 2016 Thanks for response ft offer. Will check it out Quote Link to comment Share on other sites More sharing options...
TrevC Posted August 8, 2016 Share Posted August 8, 2016 Sometimes, the A/C system relay packs up...locate it, take it out and shake it...if it rattles then it's broken. Once replaced, the A/C system may need to be reprogrammed to then start working Cheers Trevor Quote Link to comment Share on other sites More sharing options...
Jordan Cohen Posted August 8, 2016 Share Posted August 8, 2016 Thanks for that, Trevor. How do I reprogram Quote Link to comment Share on other sites More sharing options...
TrevC Posted August 9, 2016 Share Posted August 9, 2016 Well I only know it for the Honda system...which may be completely different but it was a case of holding the mirror and rear screen demist button and pressing a combination of other function buttons within a certain timeframe. This then puts the system in a relearn mode and it cycles through the system and then is reset. Quote Link to comment Share on other sites More sharing options...
TrevC Posted August 9, 2016 Share Posted August 9, 2016 There is a TSB for this problem http://us.lexusownersclub.com/forums/applications/core/interface/file/attachment.php?id=17747 Quote Link to comment Share on other sites More sharing options...
