Are they just blowing smoke?
Thanks
Went to program myself, followed instruction, did not work. Any suggestions other than paying dealer $89.00 an hour for a 2 min. job? Thieves is the common word for them.
Thanks
Humid day, A/C cools the air to dewpoint, you get FOG flowing out of the vents. Usually only lasts until the A/C is able to fully cool the evaporator down.
Or does the engine coolant not come up to temperature..??
I think the relay was made with poor quality. Once a while it must be changed. Too bad for a Toyota quality.
Once a while, you need to remove the relay for cleaning. It is like changing oil every 6K miles.
How can I remove the HTR relay from the fusebox. I already located the fuse box and also identify the HTR relay box (it has grey color cover, not the blue color). How can I remove this relay out of fuse box. I try to pull it out. I can not.
Thanks
Try to remove other relays nearby to get easy acess to the HTR.
I also took to dealer and could find no problems with the "heat". I will reference the solar sensor and climate control next time I go.
Thanks for the tips.
I had the same problem on my 2006 Sienna in June 2008. I discovered yesterday the problem came back.

All I can recall is him saying the rear has an evaporator but not a seperate compressor.
Are you sure it was oil? Usually I only get water from the condensation there.
Thanks!
I am 2005 Toyota Sienna owner. I have very low mileage less than 10,000 mile on this van. This summer, I had the front fan die on me. The fan will not turn on. The rear fan works without problem. Since it was just over 3 years old, I did not want to pay for the cost of fixing the AC fan or Heater fan problem. Today Dec 22, 2009, I finally spend an hour trying to figure out the problem. Guess what? The stupid heater relay! Since it had two of the same relays, I switched the relay to see which one was defective, Guess what? The front fan will work now. The back will not.
I looked at the part number; it is a Denso part, made in Tennessee.
Who should I blame on the failure? This relay should not break. I am so disappointed, I am seriously will think twice next time when I purchase a new car next time.
Knowing where it is made seems to matter a lot. I am buying a piece of garbage made in USA from Toyota!
Toyota! you better get your act together, the next time it happen, you will have 1 less customer!
They need to do that SOON before the Toyota name and reputation go down the drain like you know what happen to GM and Chrysler.
Even if it is bad, it's less bad than any competitor.
You actually have to reach over your shoulder and make an adjustment on the temperature control located above the left sliding door!!
My thought is, can I replace that controller with a digital controller from an XLE and it function correctly? Can I replace the one up front with a digital one as well?
It comes down to if the Sienna's all use a common wiring harness with certain wires unused on the lower end models.
Anyone with intimate knowledge of this system please chime in!
Thank you.

Any Toyota techs have advice?
No doubt "common wisdom" widely dispersed mostly by dealer service personnel/managers....
Can you see condensation water under your Sienna after using AC? Thanks.
Only on max heating and low blower speed when reheat/remix plenum internal airflow path is not active.
Most newer systems, certainly automatic climate controls, once the cabin is cooled to within a fairly narrow range of "setpoint", avoid discomforting the front passengers with outlet airflow that is TOO cold and dry.
This weekend I was sitting long enough that the engine temp guage climed well above the mid-point, (waiting for teenage daughter who was just going to be a "minute") so I know that the coolant was more than warm enough.
I often have the controls set to recirculate and am not sure if the same problem occurs when not in recirculate mode.
Since I get warm air once the van starts moving, I am assuming that the heater core isn't plugged and that the valve to the core must be open (or are those bad assumptions?)
This is a 2005 Sienna with 113k miles. Electronic dual controls from heat/cooling.
Any ideas?
