mbradburn Posted November 19, 2012 Share Posted November 19, 2012 Lexus can't figure this one out - often the A/C on a hot day will start blowing warm air without warning. Changing any and all A/C settings has no effect. However, if I stop the car, turn the engine off, and then immediately turn the engine on, the A/C works as normal. Usually doing this once will fix the issue for the remainder of the ride -- on occasion I have to do the off/on routine a couple of times. Anyone have any ideas or have run into the same problem?

RX400h Posted November 20, 2012 Share Posted November 20, 2012 Does the AC compressor swtitch off when this happens? That'd be the first thing I'd check if I were a mechanic. Loose ground wires are known to cause erratic behavior such as this. Quote Link to comment Share on other sites More sharing options...
