My 2004RX330 with 59000 miles has developed a noise that sounds like the speedometer cable noise on older domestic cars. It sounds like it comes from the left side of the dash. Seems to disappear when engine rpm is increased. Car performance has not changed in any way.
Sharing any experience with this is appreciated.

 

You're better off describing what the sound is like. There is no speedo cable on this car as it is all electric signals now. Now I have clicking sound but thats from the A/C servos going out.

 

Damn those servos.
