Is the heater blower seized????

[Kibokojoe]

I am having a problem with the wires in the heater blower circuit overheating. I have pulled the blower and it still spins but only about one revolution by hand. Is this typical or do I have a problem? Anyone ever pulled one of these motors apart and rebuilt it? The squirel cages are a press fit and seem pretty fragile. Also the motor does't appear to be rebuildable.

The sword was replaced last summer.

I also notice that the car always blow hot air but I believe this is a stuck heater valve.

I just bought this car so I am a newbee to BMW's but I know how to turn a wrench.

Let me know

Thanks

Only blowing hot air would definitely mean stuck heater valve unless voltage is constantly zero on it's terminals. So check voltage there first.

What do you mean with being able to 'turn the blower motor one revolution by hand'?

I mean when I spin the squirel cage by hand it only rotates about one revolution.

I now have the motor apart and am inspecting the parts. I have pulled the bearings which were more or less stuck on the shaft. I polished the armiture shaft and they now spin nicely. One question though are the bushing suppose to spin within themselves. It looks like the bushings are made in two pieces. An outer and and inner race. Are these suppose to spin? Because they do not.

Replace the motor, even if you've freed it up and polished the shaft it won't last long. Unless you don't mind doing it again.

Where is a good place to purchase one?

I have contacted them about get the motor only. The cages I have are just fine. Did you have any problems matching the new shaft to the old cages?

get those old cages on and off
