AboutTed Ritter Expertise I have more than 26 years experience as toyota technician, I will be able to answer most questions related to the toyota product line up to the present year models, I specialize in difficult to diagnose problems but when posting a question please keep in mind that some situations require the used of special test equipment and diagnostic procedures especially as the newer models become more technologically advanced, so without actually having the car on hand I may only be able to try to steer you in the right direction and in some cases may have to refer you to the toyota dealer but at least you will know what you may be dealing with. Please don't hesitate to ask any questions, I will have an answer for you in most cases. When posting a question keep in mind that I reside in the US, although I get questions from all over the world I may not have an answer for models that are not sold in the US, I will do a reasonable search to try to match your model to the US model,please refrain from asking about diesel powered vehicles, I have no information for them. In most cases I will not answer questions about major modifications of OEM components, engine swapping or aftermarket products,please post a question not a statement, please provide enough basic information such as year, model, what engine and if anything has already been done to fix the problem, the more information I get the more I can help without having to ask you more questions.

Question I've got a 2005 Sequoia Limited 4wd w/50K miles; Lately, it's been extremely hot outside, and the AC is not blowing cold. I purchased a small guage and placed it inside the interior vent to monitor the temperature of the AC; In the mornings, it will blow around 50 degrees, however in the afternoons, it stuggles to blow 60, and I mean it struggles. I took it to the dealership today, they checked everything over, no leaks, vac'd and recharged the system and they said it was much better. Well-not so fast. It's not any better than it was before. I asked the service mgr if there were any service bulletins on the Sequoia's AC, he said there were not and consulted his 'master tech' who confirmed our Sequoia had no problems. This doesn't seem right, as the AC just isn't blowing cold, and it's certainly not cooling the cabin down. I've had 9 previous Toyotas and never experienced this with one just a few years old. Your thoughts? Thanks!
Answer I did confirm that there are no sevice bulletins on this year model but those vent temperature readings are not cold enough, they should be between 39-48 degrees F. There is a problem with this a/c system, the dealer should make sure they have a qualified a/c technician check this system, if they can't then you should either contact another dealer in the area or try an independent a/c repair shop.
