Default Low frequency squeak when heater is cold or on low???

My 2007 Lexus ES350 with 81,000 miles on it has a very low frequency squeak when the heater is first cold or on low. When I turn up the fan above the lowest setting the squeak will go away. I checked my cabin air filter but it appears to be clean & newly replaced. Any other ideas or suggestions to get this squeak to go away? Thank you!

It was below 0F this morning, my car was parked outside and got soaked in this cold, and my fan made the noise too. It went away once the car warmed up. It usually doesn't squeak on warmer days. What outside temperature did you have?

it sounds like its the grease in the bearings of the fan motor. I don't think there's much you can do about it.

+1. I have it too, more pronounced on the the cold days when the fan is on lowest speed (it can get down to -20 or -30 C where I live).

Can anyone tell me what the OEM part number is for the blower motor? I want the OEM not aftermarket. Looks like it's not to hard to replace but want to make sure I have the right part number before I order a new one.

I've been noticing something like this in the mornings when its been cold lately. It sounded as though it was coming from the passenger side footwell but could be up in the dash. I've only noticed it before the car warms up.

That is exactly where the blower motor is, right under the glove box...
