Having problems with your 2004 Toyota Sienna ?
2004 Toyota Sienna XLE... A/C Freon has been checked and is fine ...no leaks. Air blows but is not cold at times. Move to heat and is just fine. If I turn off the unit and turn back on then a/c is cold. If I adjust the temperature then it blow warm air again. What's the solution?
You need to have gauges put on it to determine if it is fully charged-does the compressor click off and on? If it does, it is probably low on 134A freon, and needs to be checked for leak and filled. You can buy a good set fo gauges for about $70-80 and they are not hard to learn how to use them, or take it to a repair facility and ask to have the pressures checked. Your vehicle is not that old, but it is around the age now where things like this might need some attention to work properly.
