Re: CJ-5 Heater Fan Upgrade Questions
The blower switch just routes current through different portions of
the resister for different fan speeds. It's the resister that actually
does the work of varying voltage to the motor.

True and the voltage and current dropped across them is converted to
heat and airflow in duct keeps them for toasting most of the time.

Are we talking thru carb or exhuast on this backfire problem because
this narrows down possible causes.

SnoMan,
I'll be honest, I wasn't paying too much attention as my Son was in the back
seat and I just wanted to get off the hi-way after I heard the Bang (I
didn't want to be stuck in the middle of a four lane with a child in the
back seat) I thing it was thru the carb, but not absolutely sure.
