Seems like prices have gone up. New to me 2000 LX 470 had the annoying chirping. Ordered a motor on eBay for $55 +10 shipping, which is still cheaper than buying an OEM unit. Seller has 4 left OEM Heater Blower Fan Motor ONLY Denso AY194000-5093. Link The most PITA part of replacing is getting the cage off the old motor. First had to use a mechanics pick to pry/deform the tab and then 2 screw drivers in between the cage and motor and wiggle it up for around 3 minutes before it finally got off the old motor. Washed up the cage and put it on the new motor, and reinstalled it. No more chirping.
