12 volt fan

 

I have 1986 Suburban with a bad heater blower.  I was thinking about
getting a cheap 12 volt muffin fan.  allelectronics has this for $3:

Nidec Beta V=99 TA350DC, Model M35291-35. 12 Vdc, 2.3 Amps. 150 CFM,
6,000 RPM, 57 bBA ball bearing fan. 92mm square x 38mm thick. Plastic
frame and impeller. Removed from used equipment, good condition. Four
leads, 10" long. UL, CE, TUV

Would it be powerful enough or do I have to look for something better

Or this one $18.50

12VDC 6.75" COOLING FAN

Comair Rotron "Major=99" JQ12ROX. 12 Vdc, 2.26 Amps. 6.75" x 5.92" x
2=2E" 235 CFM ball bearing cooling fan. Four wires. Fuse and polarity
protected. Metal housing. Polycarbonate impeller. UL, CSA, CE.

Or just get several of the three-dollar fans.  How many CFM do I need
to heat a Suburban?

No.


Yes. Try a wrecker, eBay or Google for parts.

I suspect that you will want to repair or replace the original.

FWIW I had the same problem on a 1982 Toyota Corolla.
Took the blower apart, and the motor brushes were worn out.

Toyota Parts did not sell the brushes, just the whole motor for $$$.

Took the old brushes to a vacum cleaner repair place, and found some
vacum cleaner motor brushes that were slightly bigger for $2 or $3.

Bought them and filed them down to fit.

Installed them, and the blower ran again for years, till I junked the
car
