#1666 of 1867 RX330 2005 - irregular ac and groaning noise from fan at high
Apr 29, 2009 (8:45 pm)
I just bought a lexus RX 330 2005 with 60,000Km (certified by the Lexus dealer) . I find it has wierd AC behaviour. It was very hot two days ago, around 33 degrees celsius (90 F) and the AC was fluctuating between very cold air and mild cold all the time. The cold air output was not sufficient to cool the car confortably. Both sides were on LO and I tried recirculate and no recirculate and the effect was the same
I pushed the fan to maximum speed and heard a distinctive groaning noise
coming from the fan. (When I shut off AC the fan noise remains there so no link with the AC )
AC and fan are not covered by waranty in on certified lexus in Canada
I do not know what is going on. and before I go to the dealer for a costly
repair could you help me if any of you have a RX330 with those three questions:
1- When your AC is on do you feel the compressor is constantly starting and stopping and the air outlet temperature is constantly fluctuating from very cold to "not so cold" .
2- in very hot weather do you have enough cooling in the cabine (i suppose yes since i did not see any complaints in the forum on that)
3- When your fan is at the highest speed , do you hear a groaning noise , or is it really silent. Noise is distinctively higher and groaning than when fan is at low speed. (This is independent from the AC on or off)

Check that the pollen filter is installed otherwise something may have fallen into the squirrel cage blower and is the source of the blower noise. The sunlight radiation sensors, left and right, can, will have, a significant effect on the level of cooling routed out of the ducts.
For quick cooldown on a hot day I always turn the system to max cooling, 65F, and adjust the fan for an "acceptable", lower, noise level.
You can increase the A/C cooling efficiency significantly, and get a slight gain in FE, by blocking the hot water flow to the heater core during the summer.

I will check the pollen filter I think it must be recheable through the glove box
#1669 of 1867 RX330 rattle in the back
Apr 30, 2009 (1:21 pm)
Been having a rattle noise in the back of the car
Tried to find out where the rattle was coming from
It turned out it is the two latches on the rail that hold the trunck cover
I squeezed two small pieces of soft plastic behind the latches and the rattle disapeared. You can use cloth or paper and it will do the job

I am having this exact issue with my 2006 RX330 and it is driving me crazy. What exactly do you mean by the two latches on the rail that hold the trunk cover?

Sorry for the delay ,
The two latches are in the back of the car where you slide in the tonneau cover
(the cover that you put in the trunck to hide your stuff inside)
What I did is insert (squeeze) a thick carton in the space behind the latch so that the latch will not move anymore.
The ratlle disapeared. It used to be very annoying when driving over a bumpy or rugged asphalt street
I lalso found out there is a TSB for this.
let me know if you are able to fix it
Or I can send you a picture
I dont know if PM is available on this forum

On my RX 330, assuming you are not using the tonneau cover, I found that if you push the latch buttons to the position towards the front of the car the rattle goes away. Good luck!

I just bought a 2006 RX330 with 67k mi.. After the deal and before paying, I had asked about an extended warranty. The closer offered 3 options. 4 yr 48000 mi for $6200. the least was $2400 for 24 mo/24000 miles.
I passed on all extended warranties. I'm gambling that I can get more from my money w/o the warranty.
Hope this info helps. There are better prices out there, but this was a lexus dealers best. It was not a CPO warranty either. Good, but not worth $6 large.
#1674 of 1867 Extended warranties

You did the smart thing by passing up the extended warranty. In my opinion they are a rip off and this is particularly true of a Lexus warranty. I have a '03 Lexus LS and an '05 Lexus RX. They are both out of warranty and I wouldn't even consider paying for the extended warranty. The Lexus build quality is such that they are not too likely to need much work after they are out of warranty if you perform the necessary routine maintenance i.e., change oil, filter, rotate tires, and a few other items on the maintenance schedule. I have now had six Lexus' and owned all of them for over 75K miles and one of them for 128K before selling it. None of them have ever needed any significant maintenance work after the manufactures warranty expired. I'm sure that there are people out there who have not had such great experiences with their Lexus but I would bet that the great majority have had experience similar to mine. Good luck and enjoy a great car.
