Hey guys - I've gotten a ton of help here and I really appreciate this site!

I have had a pretty significant issue with central locking recently that has been aggravating to think about. As I was driving down the road, all my doors randomly locked. I parked the car when I got home, got out, and locked my door - only the drivers door locked. I noticed when I locked the door, the instrument panel lights as well as the parking lights would flash... Not making a ton of sense.

I pulled the central locking relay (1993 945T), and it has the odd-shaped Hella relay. I pulled the relay open, and noticed it was visibly burned up on the pcb solder points. I attempted to resolder them, but it did not work - one of the metal strips was broken and no longer attached to the board.

No big deal - I could grab one at the junk yard and fix the issue. Well, I went to the junk yard, and hit up the 740 wagon I have been pimping parts off of for a while, and sure enough, it had the relay - EXCEPT - the relay was not the Hella relay, it was just a rectangular relay, but had the same pins in the same pattern as the Hella from my car did. I grabbed it anyways, and put it in my car, and it didnt work. Doors still do not lock with the drivers door.

Also, possibly related, the tailgate would not unlock after this happened. So, if I put my key in the cylinder, it would turn to the left as if you were locking it, but WOULD NOT turn to the right to unlock, no matter what I did. I ended up breaking the lock cylinder by trying too hard to turn the key to the right. I took the tailgate panel off, and was able to rotate the motor in the tailgate so it is currently unlocked and able to be opened by the handle. Now, if I put the key in the tailgate cylinder, there is no tension on it, it spins freely from left to right, and doesnt do anything - possibly unhooked from the latches inside the tailgate?

Would the motor in the tailgate have caused the relay to fry itself?
I have checked fuse #2 and it is in tact - my headlights and hazards both work fine.

Any help would be great!
