Electric Door Lock keep blowing fuses
My 1997 F 150 blows the 15 amp fuse each time the door lock are operated. 
Anyone have a suggestion on how to trouble shoot this problem?? Truck had an after market alarm that has been disconnected to door locks.

I would disconnect the lock harness from both doors. Operate the locks. If the fuse blows, the issue is in the wiring before the doors.
If the fuse doesn't blow, reconnect 1 door and try. Process of elimination should isolate the door causing the problem.
Did you remove the alarm or did someone else? Maybe a wire was left that is shorting the locking circuit to ground...
Good luck...
