problem #2

Dec 012009

Sienna LE V6

  • Automatic transmission
  • 98,000 miles


My Sienna has a problem heating the rear area. Even though the front of the cabin blows hot air, the back blows only cold air, it gets a little bit less coldder after about 20 mins, but still comes out cool. Now also, when the van is idling, like stopped at a traffic light or stuck in traffic, the air in the front does not blow warm air, not completly cold, but definitely no where near warm. But once I start driving above 10 mph, the heat will start blowing hot again. If anyone has a fix for this, please let me know. I took it to the dealer back in March when I first noticed it before the extended warranty expired, but they could not find a problem and sais it worked fine, I just had to let it warm up.
