Blower motor replacement

I am replacing my blower motor, what i thought was just a simple unbolting from under the battery looks like it will be a little more. What does replacing this involve I thought it was just unbolting it from the outside, but I don't see any mounting for it. Where does it mount?

It's harder than it looks, but is much easier than the typical car. you need to remove the heater assembly.

it is actually pretty easy if you have two people, lol. the hardest part is getting the heater plenum back in and getting the first nut started. if you have one person start the nut while you lift the plenum back in it is really pretty easy. my daughter and I did it on my jeep recently. I swapped the heater core and the blower motor. in a 90 you have to modify the firewall a bit to get the upgraded motor to fit. you won't have to do that. I used the same writeup that was linked to above. it really does a nice job of showing you what to do. if you are not replacing the heater core it is really easy you would not even have to split the plenum. having said that if you have not ever replaced the heater core and you are going to all the trouble of pulling the plenum to replace the motor I would swap the core as well.

If you have AC it's even more fun. I was able to do both without unhooking any AC lines but it was a b*&$h. Just take your time and have patience.

Now that we replaced it, the motor I bought off of ebay was slightly different for some reason so we did have to take some sheers to the firewall. But now that we put the assmbly back to the fire wall, ive had this wicked draft from the upper portion of the "intake" on the passenger side for some reason, any help?

Did you put a seal around the blower when you put it in?
