Hello! I just bought a 1982 315. I'm not getting a temperature reading on the dashboard, and the windshield wipers aren't turning on either. I was wondering if anyone has or knows where I can download the wiring diagram so I can get started. I searched various websites and forums, but all the links I found were broken. Thank you very much in advance, and greetings from Chile!

Welcome! This may be a very handy topic then: https://www.bmwe21.net/forum/viewtopic.php?t=13419

E21 fuses tend to corrode, so I'd first try the fuse for the wipers and give it a roll

Or just change the fuse and see what happens
