Wiring blower motor to a switch?
Hey guys I am going to be replacing my heater core and cleaning out the box to get some heat in my truck. I'm not restoring it, just want to get it working for a show next weekend that is by the ocean. Would be nice to have defrost on those cool mornings. Anyways, my fan lever is broken on the controls and I was wondering if I could just wire the fan up to a switch and have it just one speed?
Thanks |

Re: Wiring blower motor to a switch?
If you bypass the resistor it'll run on full speed (lots of noise and tons of air) and draw a LOT of current necessitating a pretty substantial switch. A rheostat type switch (like a generic headlight switch) won't work, either - too much current. Probably best off the replace your switch or hotwire through one of the speeds in it.
