My Lexus has started to make a strange clicking noise while driving. I thought at first I had a screw or something in my tire. Checked all of the tires and there was nothing. I also removed all the tires checked the brake pads which were fine, and lubed the brakes. The clicking won't stop and I have no idea what else it could be. It clicks while driving and clicks faster as I accelerate. Any ideas?? THANKS!

I have a 2004 RX330 that has developed a clicking noise in the front driver dashboard. It occurs when the air conditioner is running in hot weather. When the air conditioner is turned off, the clicking noise continues for a few seconds and then it stops. The Toyota service dept. has been unable to duplicate it; however, after I leave the dealership, it clicks all the way home. Has any other RX330 owners experienced this problem?

I have RX300 about a year ago it started in the passenger side took it to the dealer it stopped the noise but when I explained it to the person he knew what the problem was, the replaced something which cost $550.00 the noise stopped but recently it came back and last night it got worst and making different noise. If you find the solution please let me know.

I have a '99 RX300 and have had this off and on for a few months. Sometimes it goes away for a couple of days. I had one dealer tech look at it and he said that he thought it was a fan in the climate control system. Unfortunately he said that he would have to take apart the dash to get to it and it could cost up to $1,000 in labor and parts. So I hoping ti resolves itself.

#6 of 20 clicking noise on the RX300 by turbulence

Hi,
 
I hope to help.
On long trips we encountered clicking noise like a rattle or "rapid tapping following irregular patterns,road conditions, We drove down I-5 my sweetheart got up and looked around her car and pushed panels in and such, it was located in the rear area by the cargo area. I remembered the Licence plate frame rattles because lexus and toyotas bolt on only at the Top of the frame.
close the trunk and listen to the "RRAAPP" sound. Case Closed. I am reluctant to drill two holes for the lower licence plate frame, but may opt to
attach a couple of rubber bits to quiet it down.
Cheers!

I had a similar annoying noise with the root cause being found in the air-mix servo. This servo motor box is one of three I believe and is located on the passenger side of the climate control system and accessed by removing the glove compartment (4 screws) and the panel down just above the floor. The servo in question is located behind a couple of heater tubes and you need a stubby phillips screwdriver to remove it. Disconnect the wiring plug. The servo has a damper actuator on one side. Hold with the actuator down and pry open the case. Don't fret if the snaps break because the unit is held together with screws anyway. Clean the contacts inside the box and re-lube the gears and contact plate with silicone grease. Reassemble and reinstall (kind of a pain). Works fine now in my auto (all is quiet again!) and saves hundreds of bucks vs. a visit to Lexus service. Shield the servo from heater tube heat with some aluminum reflective duct sealing tape. I think the heat breaks the lube down and caused the servo voltage to become errant, causing the servo to "hunt" and generate annoying noise. Good Luck.

#9 of 20 Knocking Sound From Front & Rear Wheel Areas by bleighton

I have a 2004 Lexus RX 330 that has 100,000+ miles. Just recently, a knocking noise comes from the front & rear wheel/suspension as the wheels go up or down an elevated driveway curb. It will do the same thing on the open road but only when the road is uneven. Do you have any idea what is causing it? I assume it might be a costly repair so do you think I can ignore it if it is not annoying?

I had this kind of noise when I first go my '99. It was a front strut. It was replaced under warranty. It was difficult to get it addressed because it only happened when the car was cold for some reason. Had to leave it with a tech overnight so he could hear it in the morning.
