Aggggh! The Dreaded Heater Fan.

So I don't know if there is a more posted about topic than the blower fan and the heater box.

I've learned a great deal from this board about the topic. I knew it would a big task. But OMG, with the FridgeKing AC system in the way it was a good hour long wrestling match. The AC system needs to be restored anyway so I decided to pull it out with the heater box. All day later I have both out and sitting on my garage floor. Now the task of finding a reasonable price on the blower motor and the time spent on the box rebuild.

 

Anyone have a good source for the motor, I've seen a big range in prices and I don't want to break the bank.

 

Thanks for any help you can give.

A Porsche fan of some sort works too. Polarity is just backwards. No biggie. Usually pretty cheap too.

If the fan on your old motor is good (not bent, hub not loose from the blades) and the old motor is shot, you can remove the fan from the old motor without too much trauma:

1.  carefully measure exactly how much armature shaft is protruding from the fan hub, so you'll be able to place the fan in exactly the same spot on the new motor.  Otherwise it'll either hit the heater housing or the motor.  And mark which side of the fan faces away from the motor.

 

2.  saw through the armature between the fan and the motor housing, leaving the stub in the fan hub.

 

3.  set the fan hub on a suitably-sized socket and use a hammer and drift to drive the stub of the armature shaft out of the hub

 

3.  using another suitably sized socket, carefully drive the fan (be sure and reinstall with the correct side facing upwards) onto the new armature shaft to the same spot as it was located on the old motor.

 

Once you have the heater box all reassembled, test the fan/motor before reinstalling the whole heater just to make sure the fan isn't hitting anything.

 

You're done.

I have a cleaned and working heater motor with fan for sale, and I think I can beat any other price you've seen.  Problem is that I'm on vacation and won't be home where the motor is until the beginning of November.  I don't remember my asking price but it's in my records at home.  I also have a picture, but it too is on my home computer.  Let me know if you're interested.

Thanks Mike. I still have the wrong motor (the one without the plastic cladding) sitting brand new, clean, and unused in my basement. I'll sell it to you for cheaper than you can buy it anywhere if you want it.

    BMW Neue Klasse - a birth of a Sports Sedan

    Unveiling of the Neue Klasse Unveiled in 1961, BMW 1500 sedan was a revolutionary concept at the outset of the '60s. No tail fins or chrome fountains. Instead, what you got was understated and elegant, in a modern sense, exciting to drive as nearly any sports car, and yet still comfortable for four.   The elegant little sedan was an instant sensation. In the 1500, BMW not only found the long-term solution to its dire business straits but, more importantly, created an entirely new

    History of the BMW 2002 and the 02 Series

    In 1966, BMW was practically unknown in the US unless you were a touring motorcycle enthusiast or had seen an Isetta given away on a quiz show.  BMW’s sales in the US that year were just 1253 cars.  Then BMW 1600-2 came to America’s shores, tripling US sales to 4564 the following year, boosted by favorable articles in the Buff Books. Car and Driver called it “the best $2500 sedan anywhere.”  Road & Track’s road test was equally enthusiastic.  Then, BMW took a cue from American manufacturers,

    The BMW 2002 Production Run

    BMW 02 series are like the original Volkswagen Beetles in one way (besides both being German classic cars)—throughout their long production, they all essentially look alike—at least to the uninitiated:  small, boxy, rear-wheel drive, two-door sedan.  Aficionados know better.   Not only were there three other body styles—none, unfortunately, exported to the US—but there were some significant visual and mechanical changes over their eleven-year production run.   I’ve extracted t
