After operating the A/C, I read on this forum to run the heater on high to dry out the air ducts because the smell can sometimes have a musty odor.

Well today, after turning the heater on, I turned the A/C back on and the passenger side would not run cold, at all. It would run hot like the heater on that side was still on. I tried changing the temperature on the dual climate settings, pressed the A/C button on and off and tried the different air flow options but nothing worked.

I replaced the battery today and tried the A/C and now it's back to normal. Has anyone else had these issues or know how to fix it?

 

There's a known servo issue that Lexus has provided extended coverage for. Take it to dealership, they'll reprogram the a/c system and run a hardware test. Will replace anything that fails.

 

TY! This is very helpful information!
