Looks like you have the info you need so this is just an FYI... I thought my TJ had the blower motor inside and I finally had a look at it. They must have made a change sometime. My 05 has the motor hanging down above the passenger side. It does not go throught the firewall. Looks like you just turn the assy to remove it (there are plastic bayonet type lugs on it). So there are two TJ blower motor styles (or maybe even more). Best of luck - John
