Just thought I would chime in as I am going through a similar problem. My fans are not working either. (there is a whole thread on my personal headache). I believe I have found a solution. I found an old thread on here from back in 2008 where a statement pasted from another site said that a fan motor from a 2003 toyota corolla is the same motor you simply need to splice in the plug from the old fan motor, attach your blades, and reinstall. I do not have the part number as I just called NAPA and told them what I was doing and they ordered them. They will be here tomorrow at 0800 but I have to work my 24hr shift tomorrow so I won't get them until Thur around 1300 to double check that they are the same. If they are the same they are a little less than 50 per motor so that beats 350 for a new fan assembly. I plan on posting the info in a new thread Thur if everything works out so that it can be referenced later for those with the same problem. Good luck!
