I will check out the driver door solenoids. I have only done minor work on this car (I usually take it to the shop). I did work on my previous car (85 300ZX), and i think its time I get the toolbox out and work on my 300D.

The trunk always need to be locked/unlocked manually. It behaves like its completely disconnected from the power system, so I have to go and lock/unlock it every time i need to use it. It used to work fine, this problem only started happening 4-5 months ago ..
