Heater blower rebuild, Preferred method or parts? Options

[Van B]

I got no movement when I put 12v to the wires and trying to spin the fan by hand is a challenge so, I think it’s dead.

Now what to do? I see pelican parts has a Bosch motor only, a Porsche fan+motor assembly, and a URO fan+assembly.

What have you folks done for your heater blower rebuild and how has it worked out? (IMG:style_emoticons/default/poke.gif)

I’ll say up front, I’m biased toward the Bosch motor for two reasons: 1.) It’s a Bosch 2.) I’m not excited about a plastic fan in the engine bay.

Thanks,
Van

Sometimes things are just plain worn out.

These really simple DC motors used in both the rear and the front fresh air box don't really lend themselves to rebuilds.

If you really want to stay on the rebuild path your best bet is going to be to find a very similar DC motor and adapt it to the impeller and housing.

Not saying it can't be done but if you've got one that is seized, that isn't a great starting point. If you want to see how badly this can go, see post #55. Yes, it's a front air box motor but the principle is about the same. Sometimes it can be done, sometimes it's a lost cause.
