First, I have a 2006 RX400h with 65k miles. Just recently the driver's side stopped cooling and it's 90+ here. The passenger side chills just fine, but the driver's side is blowing moderately warm air. Any ideas?

Can we assume you do not have the settings in dual mode? Have you tried setting the driver side temp down as low as it will go? Do you have the recirculation button on? Have you tried to change the mode settings to see if cold air comes out of the different vents? Do you have a clicking sound coming from underneath the dash?

If everything seems to be working as it should you might have a bad servo. Hard to tell.

Moderators, perhaps this should belong in the Hybrid section as there may be specifics to the RX400h.
