Re: CJ-7's heater motor upgrade
I know two people who have put the "Blazer" blower motor in and they
both say that it is by far the best and simplest upgrage they have
done. Like Mike said, on low they say it puts out more air than the CJ
blower motor. And, the blades/hamster wheel on the CJ blower motor
bolts right up to the Blazer one. I help with the installation and it
is very simple. All you need to do is cut the hole in your firewall a
little bigger and everything else bolts straight up without any further
mods. This is the way to go. That is my opinion for what it is worth.
Good luck.

Re: CJ-7's heater motor upgrade
I was thinking a bit, and the 89 YJ motor matching the part number for
the blazer doesn't work. I have changed a couple YJ heater motors for
the Blazer one, and the blazer one was physically bigger and the owners
did notice an increase from stock...
