EDIT: Nevermind, i found something to try.
i'm looking for squirrel cage blower with enclosure, 12V, in the ballpark of 4-6" OD. thinking there's got to be some small-ish car heater / defroster that would use something similar, but most of the enclosures i'm seeing in my basic search are part of a much larger assembly.
suggestions?
Thanks!
I'm guessing this is fighting Challenge budget, so the couple of options at McMaster-Carr are out. It makes sense that the actual automotive stuff is all built in unit with heat exchangers.
I'd try Banggood or Vevor or similar for a cheap fan.
Many years ago I bought a cheap package tray defrost fan at the local discount parts place when such a thing existed. I can't imagine there's been a market in decades.
How much air do you need to move? There are tiny ones that go for down around $10, but you'd probably need two or more, and it still wouldn't probably be a fast defrost...
Z car guys use a Kia Sportage part that's available in junkyards pretty easily, if you want a starting point? Similar in size maybe?

Doh! i didn't state the application. I'm going to use these to blow air through MonZora's header heat shield boxes.
i bought a couple small plastic ones with tiny little wires on them, i'm guessing they're intended for desktop computer cooling? IIRC they're rated at 30 cfm. I haven't installed them yet because (1) i don't have the heat shields complete yet and (2) their outlets are rectangular.
i just ordered a couple of bilge fans, they're in-line vs squirrel cage. they are designed to slip-fit in 3" vent hose and should move about 120 cfm. These will be much easier to mount and plumb, so i'll find a way to get them into the budget.
I was going to suggest bilge fans, the packaging makes them super easy for this application.
97-03 Cadillac Seville rear blower motor is a junkyard option.
I plan to use one to ventilate the back of the hearse. I wanted something with adjustable speed and quieter than a bilge fan. I'm sure there's a more compact and adaptable option out there for your application.

Hi , where is this hiding on the Seville and do you also need to pull the dash switch ?
thanks for the info
Wow, I shouldn't post before coffee. It'd be a 98-03 Seville (-04 if in Canada). Not sure what blower is in that picture above, but this is the one I was thinking of.
I can get some in car pics and rough measurements tonight once swmbo gets home.

Front of the center console. There's a slider for speed and a knob to adjust the blend door on the back of the center console behind the arm rest (so it can be adjusted from the back seat). I hope this means it's a stand alone system and doesn't need a computer or module to operate. I can't find the FSM with the description of the system, but here's a diagram from the center console removal section. Blower in red, blend door in green, exit in blue.
This one looks interesting, 08-09 cts according to the description, tho it's listed by the same guy as that first pic I posted, which was incorrect.
They have in-line blowers for air-cooled VW heater tubes, also in-line bilge pump blowers. Might these be the way to go?

I'll keep that in mind when it's time to add heat and defrost, looks modular enough to be hacked into off-label use.
"bezos personally guarantees they'll be here by 10PM tomorrow."
We have an Amazon warehouse on the edge of town, I order stuff before lunch and it gets here well before supper. Weird, as I can begin tracking the package about ten minutes after I order it . . .
In reply to MuSTANK :
I ordered them last Monday, Prime, arriving Thursday. Thursday came and went, new promise is 7/24 by 10PM.
Betcha that I could have ordered them for you, had them delivered to me across town and mailed them off to you in less time . . .
The fan assembly from my long since departed 1973 SAAB 99 sounds quite like those dimensional parameters.....newer is always betterr nebber mind
