330Lover

No...I'm setting it manually when I first get into the car to 78 degrees until the car starts to warm up, and then reset it to about 70 when it warms up. But the heat still comes out blasting hot.

Would the ambient air temp sensor cause the heat to keep pouring out until the car reached whatever temp was set? Or should the heat cool down when set to a lower temperture?

I own a 05 Rx330 and the heater does not cool down after adjusting the temperature from 75 to 66 degrees. The heat that comes out at 66 degrees is so intense, I have to turn it off to be able to breathe, or open the windows.

BARTKAT: Thanks for the explanation. That seems to be more reasonable than what answers I have gotten from the dealer!

I purchased an RX330 three weeks ago after owning a RX300 for 3 years. The headlights do not seem to be as bright as the old car and even seem to look more tungsten (yellowish) than the Xenon (bright blue white) Any chance the color tempurature of the HID's has been changed in the 2005 models?

I was very happy with my RX300 and it was coming off of lease, so I traded it for RX330.

Much to my surprise I drove a new Rx330 out of the showroom last night and traded my RX300 6 months early. Never expected they'd let me out of my lease early and have a lower monthly payment to boot! It rained hard this morning and when I opened the front door the rain poured off the roof onto the seat soaking it. Obviously a design flaw. The car is only 14 hours old and I hope it's the least of any problems I'll experience. I love everything else about the car and can't wait to leave work to drive it again. :D
