Heater Parts question
I am replacing the tub on my '83 CJ7 and there is some electronics on the
heater ductwork that I do understand. Just above the vent by the passenger
floorboard there is a three wire plug that goes to a coil inside the
ductwork. Could someone tell me what this is or it's function? Thanks, Dan.

Re: Heater Parts question. Now CJ7 Fan change too.
That is the fan speed resistor block.
While you are in there you could convert the heater to a big GM blower
that will defrost 'all' the windows, literally cook your feet and allow
you to drive at -25 with no gloves, boots, ski pants or parka on. All
for about $25.00!
It puts out more on low than the stock one does on high and that is no
exaggeration. It will _even_ de-ice that little triangle in the center
of the windshield and the passenger mirror corner in a snow storm! I
haven't needed to use full defrost yet to do that either which means the
toes stay hot.
Here is a link on the job:
http://www.off-road.com/jeep/tech/body/heater.html
There are two blower motors some parts stores have on the shelf. The
cheap regular one and a premium one. You want the cheaper one which is
the one with the shorter shaft. The premium one has a shaft about 1/4"
too long for the Jeep. Best is to take your old motor with you just to
make sure.
You just need to make a slightly larger hole in the firewall to fit the
larger motor, everything else is a direct fit. The Jeep squirrel cage
fan fits right on. I used to have a link on an easy hole cut, but it
doesn't work anymore.
