I posted this same problem on the forum a few months back. Since then, I've gone back and forth to Tustin Lexus to see if the problem could be fixed. No such luck!? The mechanic acknowledged that he had felt the same hot air on a test drive but it could not be duplicated on a consistent basis. The lead mechanic went with me on a test drive and said the hot air was normal. I don't think so. I'm glad I'm not the only one that experienced this problem. Could it be a 2002 model year problem?

To answer the queston, push your mechanic a bit to get this corrected as it is not normal. Most likely a mixture solenoid is defective. Experienced in other Lexus's I have owned. Simple fix. Sometimes a bit tight to get to. Solenoids generally run around $150.00. Labor a bit more. This is not a common problem with the car and is EASILY resolved with the correct mechanic, persistent customer, and or both.

The air temp coming out of the vents will be that of the last temp setting. Even with AC "off" and blower not activated the air temp will still be the last you had set. This is due to the "positive ventilation system" which is constantly feeding fresh air to the cabin and exhausting stale air out. The temp of the positive ventilation air will always be that of the last setting you placed in the thermostat. So, if you car is too hot then always set both driver and passenger settings to the lowest possible (65).
Hope this helps and doesn't confuse.

I had a '96 SC400 that felt like it was on fire in the driver footwell. Took it to several Lexus dealers over the years and one measured the inside temperature (in the footwell), made an adjustment to the insulation around the catalytic converter (which is directly beneath the center console storage bin); this lowered the inside footwell temperature 50 degrees but IT WAS STILL UNBEARBLE! Traded it in on a '03 SC430 and have not noticed a problem.

I have noticed that heat comes up from under the car more a traffic lights in the SC then in the other convertables I have had in the past. I'm not certain if it is coming from the engine compartment or the exhaust under the cabin. It may be electric fan related and all of the ducting under the cars to reduce noise. No issues when it is moving.
