    Hello

    On my Prius the Blower motor for the incar ventilation system has stoped working correctly .
    it sometimes completely stops blowing while on the full speed setting
    and then starts working at a low speed then stops again
    a Gentle tap can get it to start working again .

    To try and resolve the problem I removed the blower Motor and cleaned it with compressed air and a great amount of dust came out .I then used Contact cleaner and a Teflon spray lubricant but the problem persists !

    my questions are
    1.has anyone successfully repaired a blower motor
    2.is it the brushes that wear down ( I am guessing )
    3.if you did repair it what new parts did you fit and is there a write up on how to do it

    The unit is a sealed unit and it looks like it cant be taken apart

    but I will try and fix it once my new motor Comes in [​IMG]

    there may be some threads here iirc. but you have to isolate the problem between the switch, wiring, circuit board and motor, don't you?

    I seem to recall a thread where someone did, in fact, take it apart. I think I saw the thread here within the last year (of course it could have been an older thread I just saw for the first time). I do not have many ideas for a search strategy that would allow you to find it, other than "it was about the blower motor and had disassembly pictures."

    I want a search engine smart enough for a query like that, but I don't know of one.

    In the US, some Gen 3 Prii came with a solar panel and an unoccupied ventilation mode. In those models, a brushless blower motor is used. In models without that option, the blower motor is ... brushful.

    I replaced this blower Motor around 200k miles ago ,its 100% the Blower motor and not the switch or relay etc. the last motor I took out I tried to repair to no avail. but wanted to know if anyone has actually been able to make a viable fix for the issue

    will try the Search ChapmanF thanks for the idea of a word string
