I have an issue with my 1995 e320 coupe.
Car started and ran fine. Then one day it was as if my battery was dead.
BUt I found out the fuse to the door locks blew out. Well I put one in and it started. BUt it now blows the fuse as soon as I put one in.

I haven't fixed the issue. A correct diagnosis and steps to fix issue gets a free dinner for you and your significant other.
