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 My query is regarding the air-condition compressor in my car, which will not engage unless I put the blower to the maximum speed. Thereafter, the compressor will continue to function even though I lower the bower speed. I have changed the blower switch but the problem persists. I have asked around and the answer given to me was either the compressor or the thermostat needed attention. If it is the thermostat, how do I get excess to it and check whether it is faulty?
Answer The blower motor uses a resistor to provide the different speeds, since it only works on high speed the resistor is probably burned out and should be replaced, it is located below the glove box in the air duct housing and has an electrical connector with some wires on it.
