85 240 wagon heater fan 200 1985

I'm having a problem with my heater fan - it was working fine but I would have to switch it to 3 or 4 to get it going then turn it back down to 1 or 2. There was no noise or smell. Turned the car off then on re start the fan would not turn on at all. Fuse is OK, suspect switch but my mechanic says he has never seen a switch fail, always the fan itself. Any ideas?

thanks

Jeff

    Jeff-

    One thing to add- do it before any extreme weather- I started this right before a string of hot and humid days, and I missed out on the brick for too long as a result. Do it quick, before the cold comes.

    Sorry 'bout that. 240 Blower motor replacement is a sort of rite of passage.

    Fan speed #4 is direct, no resistor in the circuit. So if it will run in speed #4, failure is in the resistor unit.

    The challenge with the blower motor replacement job is that so many little parts (big ones, too) have to come out to get at the motor. That means having ways to tag or bag them, to have a chance at getting things back correctly. One BB'er took photos after certain steps.

    Not a lot of different tools are needed, no special tools. Getting the clips off the turbine housing halves takes some ingeniuty, as does the removal of the turbines from the motor shaft. Also, the rubber things that hold the defroster ducts in place is likely brittle, so be careful there. Again, use ingenuity.

    My turn at that job was before the advent of the BB, but I had a copy of the Volvo instructions, fortunately. Back then the dealer quote was $105 USD for the motor and 5 hours labor.

    The 5 labor hours are likely the same, but the dealer rate is now $100 an hour. Thus the incentive to learn the DIY methods. Also the motor and resistor can be obtained at a better price. Quality counts in this one, once a car is enough.


    Good Luck,

    Bob

    Most likely you are off to Blower Motor Replacement Land. Many have gone before you, some did not make it back all the way. But we can learn from them and follow the trails blazed by those early pioneers.

    I highly recommend pulling both seats, pulling and the dash. I used this web site as have many others to pull the dash. (http://volvo2.homestead.com/Dash.html)

    Seats are held in by four bolts and easy to remove.

    And doing the yard sale pile from Art's well photo-ed page got me the rest of the way (He does have a picture of almost everything you can find in a Volvo). Found the link on Google at: http://cleanflametrap.com/

    Motor should cost around $75 at a Euro Parts place. Plan to use profanity and about 8 hours of your life. But when you find out what you auto repair guy will want, you will really want to do this your self.

    One final recomendation. Go to a Pick Ur Parts and pull a dash. Save a few of the screws, get some extra blower clips and practice on a junker before going into your dash.

    Good Luck,

    PT

    Hi Jeff,

    It is the fan motor. You might as well bite the bullet and plan 10 hours for a replacement. I would also replace the speed control resistor while you have it apart.

      I second Will's suggestion. The resistor is only a few bucks, and after you replace the blower motor you will come to realize that:

      1) The resistor takes almost as much work to get to by itself, but is easy to get at while you're replacing the motor; and

      2) This is not a job you'll want to repeat any time soon.

      Read up, take your time, and set aside about 8-10 hours before the car needs to be back on the road. You'll be fine. Good luck!

        The other alternative to the resistor replacement is to use one from a 740 and cut a hole into the airstream for external mounting. The wires have to come outside of the housing for that one. I only would recommend it if the motor is good and the resistor fails.
