I have a 2022 Lexus RX 350 base with 2k miles, automatic which I just purchased weeks ago new from a Lexus dealership in my area. I noticed when the outside temperature is less than 30 degrees, that there is very cold draft near the drivers door area. I feel that cold draft while siting in the driver seat and my left leg feels very cold however my right leg feels the heater. I am assuming one reason is because the vent is on the right side of the drivers seat?

When I touch the interior door or bottom part of the door it is cold! I should not have the left and right side drivers seat of the interior cabin different temperatures right? This is a very expensive car and I am not too sure if this is a door insulation issue or a heater issue?

I went to the nearest Lexus dealership and asked a service tech who old me that I am supposed to turn the heat setting to the AUTO function which is a hard key instead of using the manual face/foot heater which i was using.  In my previous cars when I used AUTO it would heat the entire car and all the vents, face, foot and side vents would heat the entire car. With the Lexus, when I choose the AUTO button for HIGH heat, the vent for the foot area and the side vents are the only vent that blows the warm air, not the middle vent. I just want the drivers side to be warm with no cold draft near the door!
