Help: Fuse keeps blowing after I replaced drivers side mirror

[ThomsonRacing]

Looking for some help trying to figure out why my power mirror/power window/dome light/glove compartment light fuse (fuse 4 in the owners manual) keeps blowing on my 01 F-250...

I had a mirror that need replaced so I finally got around to the project today to install an aftermarket mirror on my 01 F250...The installation was fairly simple, but as soon as I started to adjust my mirrors, the fuse blew...I replaced the fuse, went to adjust the mirrors again, and it blew...I replaced the fuse again, and verified all of the lights were working as well as the windows...I could use all of those with no issues, but as soon as I went to adjust the mirrors, the fuse again blew...It didn't seem to matter whether I was adjusting the drivers side or passenger side mirror...I had a fuse blow when adjusting each...

Any ideas? I obviously have a short that is causing this, but I have no idea how I'm going to pinpoint it...The replacement mirror plugged directly in...I thought it might be a problem with the mirror and the wiring, but I think I can rule that out because I would expect to be able to adjust the passenger side without the fuse blowing...

Any help would be greatly appreciated...

unplug the mirror (new one )run the switch if it doesn't blow it's the mirror.
