help diagnose door lock fuse problem

[ertech]

hi guys car is a 89 Turbo I tried posting on that board with no replies
.I have been at this for 2 years .door lock fuse keeps blowing after a few days .happends randomly ,I only notice when I try to lock the doors and no respond .
this is what I did so far .
1-the fuse for the hazards / doorlocks/oil cooler fan/alarm are on the same circuit .
I separated the wires going to that fuse with each it’s own fuse .
The only one blowing now is the doorlocks .
2-I disconnected the console switch near the shifter and still blows
3-I the replace the door lock relay and still blown.
4-I disconnected the plug going into the right door
5- then the left
6-passed a new red wire from the fuse till #6 of the relay
after all this it still blows
7- the microswitches work since I am able to arm the alarm even with the door lock fuse blown

in the diagram of the relay at #6 it shows 1 wire but there are 2 red ones ??I a not sure the 89 wiring is the right one for my car since its a late 89 and I dont have a key for the alarm in the door jam
what should I try next??
thanks guys

I remember fixing a door lock issue on my 85 years ago. I had a chafed wire inside the door. The wires also get worked as they pass through into the door near the door hinge area. You might visually check there. Consider checking the blown power lead resistance to ground.
