RX350 07' - knocking noise when a/c turned on
The car:Lexus RX350 07', 190,000 KM, automatoc transmission
The problrm:Knocking noise when a/c turned on
I dont know what is the soutce of the noise, initialy i thought it came from the engine but drom closer inspection, it seems like it came from the belt tensioner or one of the pulleys. the sound starts only when the A/C turned on and stop when A/C turned off. i tried to see if ther is any plastic/metal movement but apperantly there isnt.
So, how can i find the problem? has anyone ever saw it before?

If your compressor is making noise, there are 2 possibilities. Either the compressor is failing internally, or there may be insufficient refrigerant in the system to circulate the oil.
