bump for this thread. I fixed his mtv motor. These things are just standard motors so they are serviceable. Although the design is custom, it has some a very elementary design. Just find someone with some basic electric motor know-how. Ill post some pics of what i did soon.
now our problem is fitting the motor along with the shaft spring so that it closes upon loss of power to the motor. I tried to look at the service manual and it has absolutely nothing on fitting the mtv into the plenum. Does anyone know how to do this? This is driving me nuts.

wow, 03atx doesn't have that car anymore. That mag intake is now in my car.
I brought the motor over to the aviation shop i worked at during that time. Two mechanics there had a look at it and walked me through some of the basic parts. First, the motor is a brushless motor. This means carbon brushes are not attached to the commutator. This simplifies things quite a bit here. The motor is also just a basic brushless motor. The issue lies with the winding pattern. This won't be an issue unless you need to rewind the motor. Rewinding would cost you more than the MTV is worth.
First, Are you sure your mtv is dead? If you don't know, plug the mtv into a direct power source like a small 9v battery or rig it with some wire straight to your car battery. leave your car off and if it still works you should hear it engage.
You also want to be sure there is no dirt, grime or rust on the mtv. the best way to check for this is to remove it from your plenum and move it around with your hands. If you hear a grinding noise, you have a rust issue from within the motor. The MTV i worked on had rust issues.
If it works, its another problem you are having. If it doesn't, it might be time to crack it open. Before doing this, be sure you have no frayed wires. This particular motor had some fraying on the negative wire. If that's the case you still need to open her up to get some good wire in there.
Replacing the wire can be tricky. The easiest way to do this is to carefully cut the wire as close as possible to the lead that is attached to the plastic housing. Once you have that, slide a new piece of wire into the plastic housing. Then carefully solder your new wire in from the inside of the housing.
Opening it is quite easy actually. Look towards the metal face that mates with the plenum. There you will see two plastic tabs that stick through. These are coming from the plastic housing around the motor. Cut these off with a good set of wire cutters. Grab the plastic housing with your hands and tap the hanging edges of the metal with a small mallet or hammer. It should begin to loosen. If it does not, use words like dammit multiple times. That tends to work for me.
Once you have it open, check for any obvious physical flaws, mold, rust or mildew on the copper windings of the motor. Check the leads on wire and the attached leads on the plastic housing using a miltimeter. check the commutator (its the area that touches the leads inside of the plastic housing).
If it's dirty or rusty, you can clean it off. I suggest cleaning the motor with electric contact cleaner. If it is rusty, you can try to remove the rust with something mild. I used tons of wd40 while moving the motor around. Afterwards the only other thing you can do is to try the motor out. If the windings on the motor are messed up you can have them repaired. The only problem is, it's going to cost you more than buying a new mtv.
Closing your motor back up to the housing is simple. Carefully place the motor back in making sure you do not crush the leads that are attached to the plastic housing. just before closing it shut for good. Put some rtv around the sealing edge. It will prevent moisture from coming into the mtv.
If you need any more help please let me know. I do not frequent the boards anywhere near as much as i used. If you do not get a response from me within a day or two, you can always contact me via AIM using the nickname on my profile.
