Ac Does Not Work Perfectly. It Only Works After Raving The Engine. Wha

[sureshdoshi]

my 2006 lexus the AC works only after raving the engine and swithing the ac on. if you turn ac on without raving the engine the ac does not work. what could be the problem?

you need to see an a/c tech to have it leak tested, no diy for it.
