I have an 06 Sienna with about 50K miles. Recently, the drivers side air conditioning is warmer than the passenger side or the rear AC. Even with the setting on LO, it is still much warmer on the driver's side. Any ideas???

Exactly the same problem with our 2005 Toyota Sienna CE. 70,000 km (43,000 miles). Toyota wants to take off the dash at almost $700.00 (taxes in) just to start taking a look. Would love some advice - thanks.

The front passenger’s side is blowing cool air; the driver's side is blowing what seems to be warmer and humid air.
