WTB: E30 Blower Motor

ruthmann88 · 03-22-2008, 12:43 PM

Well my blower motor has been making this weird noise as it must of been hitting the side of the firewall. I should of fixed the problem then but I let it persist and I'm pretty sure the blower motor is blown.

I'm broke and I need heat lol. Anyone know the cheapest place to get another one in Canada, or anyone parting out an E30 with a working blower motor.

Thanks, I appreciate it.

you might get lucky and simply be able to rebalance the motor itself.
it's located whithin the firewall...if you see/hear the fans rubbing up against the casing, you might be able to twist/slide the motor ever so slightly so it doesn't make contact any longer.

good luck!

nah, I took it out, hooked it back up and got nothing. Fuse is good, so im pretty sure its just dead.
I have a E30 parts car if anyone is willing to trade another BMW part for the motor.

Its in the manual, but look at the top of the firewall, there is a hatch, you will have to remove some clips and you may have the wiring harness strung across it. Open the cover and you will see the housing for the blower with valves at each end. Remove this inner cover and you will see the blower motor. Motor is held in by a metal spring clip. With the fan(car) off you can spind the fan by hand and see if its making contact anywhere - also if it does not spin freely its going to die soon. No contact does not mean its not hitting at speed though. Turn it on and look/listen. If the motor shaft is warped or the fan is not balanced, you can spend the cash to have it repaired/balanced with weights or just buy a known working one. The latter is generally the best way.
The resistors for the different fan speeds is located just below the fan motor. A little hard to see.

So if its not balanced properly its going to make contact? So I would be better off then buying a new one? Only problem is all the new ones are going for $200+.

You are probably better getting a used one from a member or the wreckers.
I had one that was imbalanced and I tried to balance it myself with very light weights on the fins and it basically exploded. I replaced with a good used one and there have been no problems. Just be sure you get the right style of motor. There is an early/late difference. You can tell visually, but you can also tell by looking at your inlet for the heater core, if its aluminum, its the 5" fan, plastic, 4".
