Toyota Repair Problems? Ask a Mechanic for Answers ASAP
I can probably help you, but I'm a little confused by your question; when you say "servo", do you mean the blower motor? what exactly is it you're trying to diagnose/repair?
Thank you for clarifying.
Depending on your model and options, the glove box and blower motor box might have to come out for access to the servo - just the glove box on base models (see attached graphic). Last time I checked, Toyota was selling those for a little under $200, but that was before I retired a couple of years back, so prices might have gone up.
Please let me know if you have any other questions.
