Noise from ac compressor

Lmmbjt · March 31

Hi all can anyone help I have a 2013 rx450h and I have a very noisy ac compressor has anyone else had this problem, the dealership said that it’s within tolerance and I have to get use to it they say that some rx450h are louder than others. I get the feeling they don’t want to have to replace it under warranty, my car is coming to the end of the 10year warranty period and I think once it’s out of warranty they will then tell me it needs replacement unit !! Under some conditions I also get vapours coming out of the vents on the dash see attached video! Any help would be greatly appreciated.

Not sure about the noise as i dont hear it. But the vapour blowing from the vents could just be a clogged drain tube causing moisture to build up around the cooling coils. This should dissipate after some time. The dealer should be able to clean the evaporator drain.

Does the vapour feom the vents have a sweet smell? If it smells like coolant then you probably have a big problem i.e leaking heater core which in a lexus is generally rare but not unheard of.

Hi thanks for the comment and no the small Fromm the vapour is not coolant , but did have a slight smell of electric burning but very slight I will try to get a better recording of the noise .
