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 QUESTION: I have a 94 Camry with 240K miles. I bought used and the front passenger side power window has never worked. All three other windows and moon room work perfectly. Reading the past questions, it sounds like I need to remove the door panel, but I'm unsure how to properly check to diagnose the issue. What is the best place to start and best place to get the replacement parts (junkyard, new, etc.)? Many thanks.
ANSWER: The window motor should be checked first, with the door panel removed locate the power window electrical connector, the wires are green and red. The motor goes up or down by reversing the polarity of these wires by using the switch, using a test light this can be verified by operating the switch up or down, with the test light grounded and the probe at either the red or green wire push the switch up or down, the test light should light up, reverse the light connection to the other wire and the same should happen, if this is so then the motor should be replaced. Another way to test the motor if a test light is not available is to simply disconnect the motor connector and then applying 12 volts to one wire and grounding the other to power up the motor, if it doesn't move in one direction reverse the connections, if it doesn't move at all then the motor should be replaced, if the motor tests good the there is a problem with the master switch, the passenger switch or the wiring between the switch and the motor.

QUESTION: Ok, thanks for that, I tested it, and it is the motor. Can you please provide detailed instructions on how to replace it? While testing, I saw a plastic covering, which I'm assuming will need to be removed completely. What I'm wondering specifically, do I need to put this back, it appears it will be a mess. Thanks again!
Answer The plastic covering needs to be removed, try to put it back if possible, it's actually called a vapoor barrier but I doubt that it's that important. You'll need to get the glass into a position to remove the two 10mm bolts that hold it onto the regulator then pull the glass out though the top, if it has the cable type regulator cut the cables to get to these bolts, it's the only way, remove all the 10mm bolts that hold on the regulator, once the regulator is out the motor can be removed from it.
