Blower motor restoration thread

[Eurasiaoverland]

Just to finish this off...

I could never get the nack of soldering and finally had a thought that my 60W iron was not suitable for the jobs I was attempting. So I bought a 200W iron and now there is no problem with insufficient heat. Just my poor technique.

Anyway, here finally is the finished unit. I'm happy with the result, though I won't be able to test it for a while.

That's what I've done with my OEM units many times. It's more often than not a good fix, but there's a high likelihood of motor noise just due to the nature of its brushed design. I'm still researching whether it's more worthwhile to further pursue OEM restorations or investigate conversion to a brushless motor. If brushless is possible, it would require a whole new lower housing assembly. Downside is there would be much more design and fit work needed and the final price could be $400-$500 for a complete kit (not sure how many would be willing to pay that), but the upside is that it would allow me to design a provision for a cabin air filter.

Hi, Did you take this any farther?

My motor cooked the 2 spade plug a few years ago, filled the cabin with burning plastic smell. Trimmed off the melted plug housing, leaving just the 2 spade connectors, that worked fine. Cleaned up the commutator as you did and went down to Ace hardware to find some brushes. Got something pretty close and filed them down to fit and then soldered them in. Cost me about $8 and it's been working great for the last 7 years or so.

I haven't done anymore research on this, since viable (non garbage) alternatives have been discovered after some digging by @ToyotaMatt.

Eventually I might pick up on the research for the brushless conversion again, but I have a lot of other things I want to get finalized first.
