Chevy heater fan conversion

[walkercreekbronco]

Installing a chevy heater fan has been mentioned on here several times. I was at the parts store yesterday and decided I'd try this. But while looking at the chevy motor I noticed it was only a one speed motor. To those of you that have done this: How'd you wire it in? Do you have only one speed on your fan now?

I'm not familiar with the conversion, but you should be able to use a rheostat to have essentially an infinite speed range.

Aren't most if not all fan motors one speed? The speed setting is usually controlled by the fan switch, or so I thought.

Your current switch is basically a reostat. Plug the power into the heater and ground it out. It will work just fine. It is quite a bit louder than the original, but it does pump out a lot more air. You will be happy with it.
