2004 Toyota Sienna Q&A
2004 Toyota Sienna Question: air condition problem
There are no Known service Bulletins that would indicate Toyota is having problems with their Air conditioner compressors. When an Air Conditioner Compressor fails does not mean pieces go through the system. There are filters that are replaced when Compressor is replaced. - Protech2989
Some Hondas had compressor failures that sent debris through out the entire air conditioning system resulting in very expensive repairs. - patrick mannion
Comment from Carlsbad, CA: I just had a "catastrophic" AC compressor failure in my 2004 Sienna LE/AWD on July 15, 2009. The car has approximately 93,000 miles. The local Toyota dealer quoted >$4,300.00 for complete system replacement due to fine metal particle contamination throughout. Service writer says there are TSBs on the 2004 Sienna AC system for this failure. No preventive maintenance remedy. Can happen at any time. Search the web. It is happening more frequently than admitted to by Toyota and has been for awhile. See also: http://en.allexperts.com/q/Auto-Air-Conditioning-1591/f/Toyota-Sienna-compressor-failure.htm - type47fan
I too have had the same problem. My 04 Sienna air conditioner went out at 34,000 mi. I replaced everything from the dealer at a cost of $1,800.00. That was the end of July 2008. July 2010 my condensor went bad again and the cost is $1,200.00. Toyota does not stand by its products and this van is a lemon. I have had numerous issues with this van and to this day I only have 58,000 mi on it. Items replaced: radiator, both front seat heaters, lock actuator, seat belts, and liftgate hydriolics (twice). Sliding door parts, one key fab (battery dies so does the key fab) and the other key fab I had to pay to have reprogrammed. Did I mention the van eats tires? I just put on my 3rd set I have so much money invested in this vehicle with so few miles that I can’t get rid of it. My advice is to tell everyone not to purchase Toyota's! - Visitor
