Both should move up and down, quietly and reasonably fast.

If a window does not work, this most likely means a bad motor, but check the fuse pane...

I have been thinking about this....

There is a back brace from the alternator across... plus a brace from the AC to the header.

I suspect the vibration has been there for a long time... those braces are designed to two things - quell vibrations and reinforce the main bracket. The belt pulls on the compressor, the bracket stops that pull.

I have seen where people will use a longer bolt with a spacer to attach the bracket to the head. I would try that trick.

Hey, I had the bracket that goes from the oustside of the compressor to the # 3 cylinder. I used the long factor studs, as my headers allowed it. Then I put spacers in to put it the distance that another forum member said to use when he put Exotic Muscle headers in.
Now, I have the bracket on the alternator that goes to the intake manifold.
I do not have the two other brackets installed. One goes to the alternator to the header, and the other is on the inside of the compressor to the header. Both of these go to header bolt two on the #1 cylinder. I may tackle this when I get home.
#3 isnt going to work anymore as I think the timesert came loose with the long oem bolt, being too long when torqued down..I have put a ARP header bolt back in with green thread lock.. Temp fix..
