04 Ranger heater/AC blower

My old Ranger's blower motor quit working again. I say again, because I had to replace the resister block about 100,000 miles ago (it now has close to 200,000 miles on it). I really don't want to spend a lot of money and I'm thinking about a redneck fix. See what you think and please comment. I ran a jumper straight from the battery to the blower motor and it runs just fine. I can buy an old fashion (new-old-stock) blower rheostat switch on ebay for 10 bucks. Does anyone see a problem with wiring this rheostat (fused of course) from a battery source to the blower motor?

Two things cause those resistors to go bad.
1) motor drawing more current than intended.
2) not enough air flow over the resistor.

Not sure what type of blower rheostat you're talking about but I doubt it will work.
Try it.... not much to lose.

Guess I don't understand why you wouldn't just replace the rheostat and wire harness. They are notoriously bad on Rangers since they aren't inside.
