Hi i'm new here and I have a 91 240 LE. I just bought it recently so im getting used to it. The guy i bought it from tried to explain how the power locks work to me but i was feeling very ill that day and barely learned a thing. In the end i just started tinkering a bit and i only manage to close my doors and have them remained locked if i hold the doorhandle up while closing it. Is there any other way that i am missing or is this all? Thanks.

 

that is how the door locks work, shut the door while holding the handle on the outside up
