I didn't think I would ever have the correct rear heater, when they come up for sale they are usually the older 2 speed kind, with the 2 wire connector. But
@baldboy posted one up in the classifieds the other day, and I took him up on the offer. Excellent seller! Heater showed up Wednesday, so I couldn't go to work on Thursday, I had to call in sick. This one was in great shape for a 44 year old heater, I would say. But one does not simply plug in a 44 year old fan motor:
Look at the beautiful plating still left perfect on that fan blade! The motor was stiff, so I pulled it apart and gave it some TLC. There are felts in there that soaked up some machine oil and then I placed some grease in the bottom ball and socket looking area. I wonder if that is supposed to be a bearing? If so it is seized, but it rides in that socket on the layer of grease that I put in there. On assembly, it spins nice and smooth, but still kind of stiff spinning by hand:
I touched up a few rough and rusty areas and then hit it with some self etching primer, followed by some Duplicolor Stainless Steel. But I masked off this stamp that was still visible so it didn't get covered up:
All in all, not bad for a day's work. I blew out the dirt and hair from the core, and put everything together in it's forever home. There's still work to do to it, but tomorrow my FJ40 will go to a car show with a rear heater for the first time.

Also, Winter is Coming! And I am a wuss about the cold, so I'm ready to try this puppy out!
Dang, my ride is Dirty! Didn't see that till I looked at this picture! LOL Hope everyone has a great weekend!
