Feb 05, 2007 (12:54 am)
I bought a brand new 2005 Toyota Sienna and since then have nevered got any warm air to come through the rear vents. Only the front passenger and driver gets the heated air. The back rear get only cold air. Any suggestions. Thanks.

Bring it in to the dealer - that should be coverred under the warranty.

I can't remember right off the top of my head, but isn't the warranty just for 10,000 miles? Thanks.
#4 of 179 2002 sienna raer climate control
Mar 10, 2007 (5:05 pm)
my wife and i just got a certified used 2002 toyota sienna ce. when we turned on the heater for the back vents nothing comes out (just from under the front seats) when i took it to the toyota dealership the techs said (after 4 hours) that the rear climate control does not do heat in the back just a/c. now i questiond them why would there be a controll for heat if it's not supposed to work and they had no real answer. i feel i am being messed with so they dont have to fix it. i am hoping that there is someone that might have a correct answer sinse i don't have a manual to look it up. thank you.

They are lying to you - heat works back there (or should!!!).
Now, if you raise the temp and don't adjust the mode to come out of the vents, it will just come out of the floor. Try switching the mode to vent and raising the temp - if there's still nothing, then something needs to be fixed somewhere.

I just had a terrible experience with Toyota, Our 2004 Sienna is 12 days past the 36 month warranty and has only 31K miles. Last week the AC quit working and the battery light came on. The belt had sheared. We took the vehicle to the Thousand Oaks Toyota Dealership, incidently where we bought the car and Frank, the service writer, told us that the compressor had seized and caused the belt to shear. The repair would be $1,900.00 but the bill could be higher since metal may have gotten into the hoses and the condenser. The bill is now at $3,000 and Toyota has refused to make any kind of adjustment. In fact, the Toyota company policy is that area representatives will not under any circumstances actually talk to a customer. We have owned several Toyotas and each one has had slightly poor quality. I suspect that this is a problem with a number of 2003 and 2004 vehicles. Is this another cover up like the sludge problems? Toyota has certainly damaged its reputation with this kind of behavior.

The lower vents put out warm air and the upper vents put out cold(AC) air. There is a TSB issued by toyota, where if you complain about it, they can change a couple of heater control modules(behind the dash and in the rear) to make both warm and cold air come out of either vent system. The TSB # is AC001-06 and was put out on Jan 13, 2006.

I agree with you about Toyota quality. I think it has been slipping the past few years. Toyota is getting to be a very arrogant car company too. I have gotten nothing but the run around from them concerinig a few of the problems I have had with my 05 sienna.

I think what has been happening is that instead of raising prices inordinantly as they proposed a few years ago in order to give GM, Ford, & Chrysler a bigger share of the market they decided to "stumble" insofar as QA is concerned.
But I'm not sure it's working.
