Door switch/warning buzzer diode?
Can anyone tell me the location of this diode?
Car is an '87 3.2. I'm troubleshooting electrical gremlins. I know it is unusual, but diodes can fail to a short (rather than the more common failure to an open condition) and that might explain some issues. Thanks in advance.

Yes, It is in the frunk and not easy to get to....
The Warning relay is behind oil temp and fuel level instrument gauges. The diode is about 12-15 inches down the harness that connects to the relay. You should be able to get to it from the frunk The reason I know this is because I had to repair the front harness and have attached a picture showing the relay socket and the diode for you. The large circle is the diode, the small circle is the relay socket I don't have a clear picture of the diode and socket "in place" to show you....but you should bee able to find it from here. Good hunting...

The information & photos you provided were a big help - Thanks!
Fyi, I discovered this is one of the infamous 911.617.108.00 diodes. |
