Hi everyone!
I am new here so please be gentle...
I have a 1996 318i and the driver's side door does not open from the outside even though all the other doors do. I have to climb through the passenger's door

, start the car and then it will let me open the driver's door...only with the ignition on.
I had a similar problem about 6 months ago and the fuses were changed fixing it.
Can this be the same problem? Do I need to change a fuse again?
Where can I get a diagram of these in English? My friend who helped me before has moved away.
Maybe it's important to mention that the heating was not working. Then it suddenly started working but the door stopped opening

Thank you!
