Heater Blower Upgrade Question

Re: Heater Blower Upgrade Question
AutoZone sandbagged me on that one too when I did the swap. They sold you
the wrong motor or, rather, the right motor but not the one you wanted.
Take it back, bring your old Jeep motor with you and compare it to a few
other GM motors. Beware: The wrong motor will put the squirrel cage in
the wrong place and it _will_ bind in the heater box. Go to the sales
associate that is old enough to not have pimples, s/he'll know how to find
parts that don't easily show up on the computer.
I didn't know that there were two motors for that GM application and ended
up making mine fit by changing the spacers around and adding a shim
between the motor flange and the heater box, but I'm told that the other
motor is a drop-in replacement (except for the firewall hole.) Don't try
to make it fit, your time is worth more than that.
Resist the temptation to use silicone around the heater motor at the
firewall when you get it back together. Silicone, unless it is specially
formulated for windshield installation, is reputed to eat paint and metal.
I used some butyl rubber I scored from a glass shop. Butyl is like chewed
bubble gum, stays tacky and never hardens.
Oh and, depending on how old your Jeep is, think about your heater core
while you've got the box out. Do you want to replace it now, or wait
until later?
Good luck.

Some conditions apply. YMMV. This message was packed by weight, not
by volume. TWIAVBP, local variation may occur. Dramatization, not a real
authority. Do not induce vomiting. No user-serviceable words inside.

Re: Heater Blower Upgrade Question
It looks like we have a winner! The fan without the AC fits just fine.
Some other notes for anyone planning on doing this:
1) The correct fan part number at AutoZone is PM102 and is made by Siemens.
Other parts stores may (or may not) vary.
2) With the PM102, I'd use a bit to make a 3 1/2" hole, not 3 1/4" hole
listed on the web site. I think the dimensions have changed since the web
site was last updated, as mine fits pretty darn good (better than the
factory fan).
3) The easiest, quickest way to make the hole is to use the nearby bolts
from the removed battery tray to hold down a 1x4 covering the old hole,
then drill from the inside. Note that you'll also need some longer bolts
temporarily. Total time was under five minutes to find the bolts, mount
the board, and drill the hole. Much easier than the aluminum crossbar on
the web site (although a bit less accurate).
4) Replace the heater core. It's only $35, and not worth it to pull the
whole thing apart again.
