SOURCE: I have two noise-related problems with my '99 Lexus rx300.

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.

Mine did the same thing. I had the battery replaced on the controller.and it still beeped. Then I took my key and put it in the ignition, without turning the key and took it out. Did this like 6 times and the long beep finally stopped.

When I start the car there's a loud sqeeking noise that goes away after 1 minute 2003 es 330


if it was mine, I would buy some "fan belt dressing spray" and spray my fan belts or have them adjusted. first spray them once, if sound stops a few days, have the tension adjusted. if spray does not work the first time, this is not the problem.

ATTACK OF THE 25 BEEPS!!!!


The airbag malfunction indicator light on the instrument cluster might be the culprit. Turn on the ignition key check whether the airbag light if present. The airbag light shld be on for about 6 sec then turns off if there are no faults found. If the bulb is busted the beeping sound will warn the driver for five consecutive beeps. wear your seatbelts also.

My 2005 lexus es 33o no longer makes a sound when i click the remote to lock or unlock


Some ES models have a knob near the steering wheel that turns the volume of the beeps up or down. Maybe someone turned this down too low.

I am not sure the 2005 has this.

Alarm going off all the time.


Too many possible causes for this. Take it into the dealership and have it properly diagnosed. Sounds to me to be a BCM problem (body control module).
