Blower Motor/AC Issue

[Picaz78]

Hello all. I have combed through the forum and have seen that alot of people have had different issues with their blower motor. Mine works and the AC blows nice and cold, but after a few minutes, the #8 fuse starts to melt. I first noticed a burning smell when I was driving then the AC cut off. When I looked at the fuse it was pretty much toast. The metal leads that hold the fuse look like they're burnt and it seems like the fuses melt rather than the metal strip breaking/burning away. I tried to test for a ground by disconnecting each component on that fuse (blower motor, AC compressor, and switchover valve) and can't seem to make any headway. When I tested the original blower motor, I jumped it to the battery and it spun, then seemed to stop, start and stop again so I figured I had a bad motor. I bought a new (used) one and installed it and am having the same problem. I took the old motor apart today and the brushes inside seem to be fine. Does anyone have any tips on this one? I'd REALLY love to start using the AC that I just got going again. Thanks!

By the way, if anyone is ever interested in a meet down in South Florida, I'd definitely love to meet some other MB greasers!
